There's a 1/8'' NPT plug on the drivers side of the head--that's where you want to be

aahh ok thought so, and the kit never came with the adapter to hook it up to the head plug, or is this somthin i have to look for my self?

I bought the little kit at my local auto parts store--it's got about 15' of 1/8'' nylon tubing a handfull of compression fittings and some basic adapters for about 7 clams. A few zipties and you'll be good to go.

alright can someone please post a picture of where the boost tubing goes so i can see where it is hooked up i thought i had it in the right place but it does not even move the boost neither does it have and vacuum when i put my finger over the whole, so can i please see a picture

I have nonintercooled so my plate is in the way, but the hole you need should be directly in line with your intake horn.

yeah it's in there, and i rev it up and the boost dont even budge and there no suction at all there

rbrettctd

you revving it up while sitting still? You wont notice any boost reading while sitting. You have to put a load on it. Make sure you dont have any kinks in your boost line.

mine will make 9psi WOT with no load but a 1st gen with a 18-22cm exhaust housing and H1C wont. the plug is right next to the pump on the head.

alright it still wont even boost up, i took the fitting off and put finger over the hole and theres no suction at all, what could be happening?, i drove the truck down the street truck shifted but the boost guage dident move. what do you think could be happening?

pinched line maybe?

if you have vacuum then you have problems! lol there is no vacuum on diesel engines so not havin your finger sucked in the hole is a good thing. make sure the elbow you put in the head isnt a boost elbow (they usually have an allen screw on the top). i took the elbow from my turbo and put it on the head for a gauge and put a boost elbow on the turbo to turn it up a little.

mullishacrew

ha! i knew there was no vacum the old man kept insisting there was so i asked the question, but i will try and see what i can do to get this thing to work because it's gettin annoying i wanna get the truck on the road soon.

Heres mine. I think the 1st gens have the same head?

The first pic shows the general location, boost line in the center. The second is a closer view. Sorry about the poor pics, I used my phone and it is kinda dark this morning.
