YES your right.....

THE ONLY WIRE TO CUT AND SPLICE IS THE ORANGE WITH RED STRIPE then you hook this wire to the airdog harnesses single trigger wire...

OK, I figured it out and the truck runs AWESOME. My overhead read 25 MPG on my way into work this morning. I know they are always wrong but it used to read 19. So I am optimisitc. Most of the problems I had were self induced. It is correct to say that these installs are not that hard but...2 of the fittings I received did not fit so I had to improvise a little. That was not the cause of the problems. The source of the poor flow was that I had not followed the directions as closely as I had thought. I initially plumbed the return to tank line to the engine and vice versa. Once correted no issues.

While I had the bed off I did reroute vent hoses and the supply line as well as rewire the power the way Willys posted. I feel much better knowing that the fuel pump uses the relay and now my gas guage works. (it is an orange with red wire, I had mistyped)

Having said all of this, I recommend the system as long as you read the associated posts. The directions that are included are of poor quality (Toby has apologized many times). I have a tough time putting words to actions but if I can see a picture I can make it happen. If you can follow word directions you will be money. I know I am dumb as a box of hammers so if you need to bash me to feel better about yourself, have at it.

The bottom line is:

Don't be scared. There are lots of smart people that are willing to help out.

Well that sounds better, glad you got it figured out and even happier I now have renewed confidence. Its always been a fear of mine to buy any aftermarket item to improve the performance/efficiency of a vehicle and ending up hurting the performance and reliability of it. This is why I'm debating how far I want to bomb my truck. All the info on here is a tremendous help though, so thanks to everyone for that.

Everything I have read about these systems tells me that it will only help the truck in many ways. My intent was not to keep people from buying this product. Make no mistake though, if you are a diy guy make sure you read this post and the post by 53 Willys https://www.dieseltruckresource.com/...airdog+megacab . If I had done that I would not have made some of the silly mistakes I made. Best of luck!!!

Good fix - and rest assured, my post has no intent to single anyone out, only factual info and humorous precautionary note, based on 50 years of service and customer service experience - if you could see only some of what I've seen, you'd need pause to wonder at our educational and technological world-position.

So, yeah - you get an 'atta boy!

This is the harness that was Not sent with my order, But its on its way!![guitar]

I did a test run with the electrical today to make sure I had everything correct and the airdog would work. And of course it did. Just plug and play for the trucks with the filter mounted pumps. I already mounted to bracket, to speed the installation process. So tomorrow I will be putting the airdog on and can't wait to test it out.

Mark,

So what did you do to stop your leaky OEM supply line after disconnected? Is there a cap available for it?

If this hasn't already crossed your mind, I think the hydrostatic pressure of the fuel in your tank is pushing through your OEM pump and up the supply line.

Would teflon tape work on NPT threads or is that not diesel resistant? If not who makes the thread sealant LocTite?

I was wondering the same thing.

Was hoping it would be a quick easy answer I've got the tape already and didn't want to make a trip to pick up anything before installing in the morning. If tapes no good looks like this'll work fine fuel don't get anywhere near hot enough for what it's rated: http://www.northernautoparts.com/Pro...tModelId=12733 Also the higher dollar stuff: http://www.northernautoparts.com/Pro...tModelId=12731 Hopefully autozone or whoever will have diesel resistant they never seem to have the right kind of loctite I need when I need it..

yeah I just picked a 12Mx6an adapter and a 6an cap..and plugged/capped it off.
yeah I was figuring it was something like hydrostatic pressure that was causing the leak.
it's been good to go so far

I use stuff called "Leak Lock"
http://www.highsidechem.com/leaklck.html
it seals everything!!! but I dont know if they sell it locally??...I would just find something at the auto parts store thats says it is safe on diesel fuel..

WOW Great write up guys! I've bought the AirDog 150 for my 05 and will be putting it on before to long. Thanks to all the helpful people here, I believe I'll get this on with no slip-ups......THANKS AGAIN GUYS!![guitar]

I used the yellow teflon tape it shouldn't break down like the white teflon tape does. I asked Rip at source automotive and this is what he suggested. Works fine about 3.5-4 wraps around and make sure you don't have any off the ends of the threads. Worked for me.

I found out today 07's have that very same factory bracket you mentioned up on top of the framerail right in the way. [laugh] I also found out I was dreaming if I thought I was not gonna be dropping the tank to connect the harness. [laugh] So how far below the frame rails do your AD filters hang? I cut my bracket up and tack welded it together just to bolt onto the frame and check things. I made it to run parallel with the frame like willy's but it won't work or not to my liking anyways. That crossmember (in willy's pic below) spotwelded underneath there is right in the way on my short bed QC. It's about 6 inches closer towards the cab on my truck right above where the AD would be and I need the space it occupies. It makes the filters to where they hang down too far below the frame rails if I mount it that way probably about 3/4" lower than willys'. I'm just gonna fab it so the airdog is more towards the center of the truck where that hump is for the transmission. There's plenty of room to situate the AD upwards over there. I hate to have a long bracket like that but I don't want the filters to get knocked off. Anybody out there do something different with their AD on a SB QC and have some pics? I hope the harness (ad part# 5e-2-009) plugs right in without having to tap that one wire. [laugh]

And the exception to all this is if the instructions are wrong and you are doing your install when they are closed you are going to have to figure it out on your own through trial and error. I'll find an example for you.

o-man that's a bummer about the mount on your QC SB...I figured they all would be real close to the same clearance..you should have to run the trigger wire on a 07....I do not think they are plug and play.....

Here ya go GMCTD!
 

So as per Mark (who is very helpful by the way!) the only wire to be cut and splice is the orange with red stripe. Okay sounds easy enough......

Now read the supplemental instructions and #7 states: If the tank has an internal fuel pump, it needs to be disconnected. Locate the wire harness that connects into the basket. The outside black wire needs to be cut. Tape wire up out of the way. Cut the wire far enough away from the connector so that it can be reconnected if ever necessary.
*2005 trucks need to have the fuel pump relay removed (Figure 5).

VERBATIM......word up dude?

Trust me there is more where this came from. So forgive me for trying to be special by not following the instructions to the T. The instructions definately need a revamping. Or I got the wrong harness or a lil' bit of everything. Sometimes I screw up [duhhh]. But telling everyone a 5th grader could do this? C'mon tell you what have them send you the exact same pump and wiring harness and tell me that you wouldn't be scratching your head when the instructions tell you to plug something in that isn't there.

Section 6 page 15 of my instructions. Read that and tell me what you come up with following them word for word. These insructions are general. I'm not saying it can't be done. But don't make it out to sound like it's the perfect installation guide. With help from here it can be done though.

If you need some more examples let me know and I'll dig some more up.

I look at it like this - if it just bolted and plugged right up what would be the fun in that? [laugh] But also understand there are some guys that dont have welders and stuff. Pureflow needs to make some changes for those guys.

Ah - I see you've chosen to ignore the humor and focus on the agony - even the fifth grader bit is from the recent TV show, R U Smarter than a Fifth Grader?

However, you make valid points, Sandaholic, and I do not disagree - I have not seen the instruction sheet, but they have admitted to possibly incomprehensible instruction(s) - the end solution is always in the fine print -
"Questions? Call 1-800-Bite-Me or e-mail us at service_rep_in_kjurdistan.com"

So, to end this in all political correctness: to those that were offended by my insensitivity, and to all that didn't understand the instructions or my post, you have my insincerest :rolleyes:

The pics er smudges in the instructions are pretty bad. They just came out with a new instruction manual a few days ago set that includes full color pics if you need it call these install threads look to have everything a person could need already though.

Now I believe you[laugh]

Good man;)

Well I just got done installing my airdog 150. [guitar] I did the gdp vent mod while the bed was off as well. 18-19 psi at idle and 16 psi at WOT with predator on extreme. So far I am pleased with its performance. Truck seems to idle smoother. I had to modify the bracket which seems to be a quite common problem.

Install was goin smooth, until I cut the hole for the new drawstraw to close to the edge of the tank. [duhhh] The drawstraw then hit the bottom of the tank right in the curve where it meets the side of the tank. I used 2 90 degree fittings inside the tank to move the drawstraw just behind the factory pickup. Hopefully I will not have problems with this down the road. I really do not think that I will. Other than that install was not bad.

If the airdog were ever to fail, all I have to do is plug the stock pump back in and change the fitting going to the cp3 back to the stock one. Makes me feel muh more comfortable have a backup. Overall I am pleased with the airdog. Tomorrow I am leaving for a 2000 mile round trip snowboarding trip and am glad to get it on just in time for the trip.[coffee]

Sweet man glad you got it all put together....https://www.dieseltruckresource.com/...ilies/cool.gif

get back to work

Thanks for all your help!!!!

I'm off work now[guitar] [coffee]

no problem...

Where did you locate those - Vulcan Performance as well?

On my airdog system i dont know which way the feed and return are. One has a prefitted fittin that came installed and the one next to it did not have a fitting ... which one is the feed to the engine and which one is the return.

my truck ideals and revs fine but put it in gear and and get it to much pedal it will starve of fuel and die

Take a look how 53 willy did his. Slightly different orientation because the bracket was modified, but you should be able to figure it out from the orientation of the unit: https://www.dieseltruckresource.com/...d.php?t=184672

Now, I've been looking at this closely as I would like to do something similar to mine, so if i understand everything correctly, the side with two fittings points toward the engine. The hose on the left is your tank return line and the hose next to the framerail goes to CP3:
http://i81.photobucket.com/albums/j2...f/DSC_0907.jpg

The already installed fitting is for the return to the fill-neck. The one right next to it goes to the cp3. The one by itself on the other side is the supply from the tank.
