Has anyone put together a kit for the walbro pump yet? Looking to do a fuel upgrade soon.

 

A fellow with the call name of Gypsyman is putting one together. Last I heard it would be out near the 31st!! Can't wait!!

 

Not knocking Gypsyman (I think it's cool he's putting together a kit), but it's pretty darn easy to do it all yourself... It did take some trial and error on my part, and alot of trips to the parts store. If you've got the time, it's no big deal. Currently I wouldn't have time, so I understand why some would go with a ready to install package...

guess I shoulda just kept my mouth shut...

 

Walbro, I'm going to piece my own kit together also, however for some people to be able to buy a kit that has everything you need, and no head aches, this and that, some people love that. Sometimes if you can spend a few more bucks and not have a problem I will always do that (look how many people will spend a dollar or two more to buy from a vendor of the site cause of the help you get)

A kit will make it super easy to install, especially for those that arn't super mechanically inclined.

 

I'm putting a Walbro in mine too. The only thing I haven't settled on is the wiring. It would be so easy to just hook up the wires from the existing lift pump but there seems to be some concern about how much current the Walbro draws. I don't want to run a separate wire down from the battery and then a relay. What have you guys done?

I ran a seperate feed from the battery, fused of course, to a relay. The relay is triggered by the cigarette lighter fuse which is only live when the key is turned on. This is very easy and there's no reason not to run something similar to this. My stock pump is in-tank so tapping the wiring from there is different from those with filter mounted pumps.

 

You guys that have installed the walbro without the tank pump are you leaving some kind of a way to be able to use the stock pump if the walbro ever failed? Also did you do your install like Superduty had posted or another? If you are installing like Superduty recommended where are you getting your banjo fittings.

 

I left the stock pump in place and can switch over in about 5 minutes...

My install is pretty much just like Superduty's.

You can get tapped banjo bolts from Genosgarage.com

Goodluck

 

I put in a by-pass at the Walbro itself, not with a check valve, just a regular valve. A little cheaper, but works almost the same. Atleast this way I may be able to get off the side of the road in the event of a failure. I plan on installing the Cat 2 micron filters soon like SD did sometime later this week

Most of my part came from Jegs, like hose, AN fittings/adapters, and filter head. Walbro was from eBay. Cat filter from a Cat dealer. And the wiring harness and LP elimination piece came from Rip.

With everything listed, I may have around 350 bucks. It could be done for cheaper, I opted to replace all my banjos with AN fittings.

 

I just did my walbro conversion. I left the stock in tank pump sytem completly intact and used a checkvalve to conect the stock pump inline with the pressure side of the walbro. all i got to do is put the relay back in and im back to stock pressure. I will do a write up when I have time and post some pics. I did a few things differently than ive seen posted. I also made a inline regulator/checkvalve to regulate pressure to 20 psi at the cp-3 and also to stop the bypass if running the stock pump at only 8 psi. the 8psi is not enough to open the bypass valve so you will get full pressure from the stock sytem. I also put in a perma cool filter in before the walbro so there is no junk being pumped thru it.

 

Nope, I'm never going back to the stock lift pump. In fact, I sold my OEM pump to another guy who is now carrying it as his spare. I bought a second Walbro to have under the seat, and can swap it out in 15 minutes on the side of the road. I'm thinking that I'll never need the spare pump, but I also believe in that boy scout motto "Be Prepared".

 

i instaled a walbro and ran it for a while,it did a good job however when i started to turn up the boxes the walbro couldnt keep the pressure up to my needs,i went back to a blue and will soon be installing an aeromotive.the walbro did not supply enough fuel to go 600 hp at least on my truck,the holley blue never had a problem.not trying to start a problem but lots of people are going walbro these days and i wanted my findings known....

 

Did you run A open bypass? I have 2 boxes cranked all the way up and I can only pull it down from 20 psi to 17 psi at wot. I am using an adjustable checkvalve as a regulator. there is so much fuel being pumped that there is no way your engine could burn all that. you may have not had much pressure but you still probably had the volume...wich is more important. This is the 1st report that ive heard of not enough pressure. maybe you had a bad pump?

 

I second that King. I've been in near constant contact with Gypsyman since I found out he was putting together a Walbro kit. He has a dyno verified 600+hp, and through his extensive testing, he said that even the lesser rated GL391 is plenty of pump for his application, and will be offering the 392 only for guys who like to go overkill with their stuff.

 

Ok now I am curious....how did you manage to leave your stock pump in place and not cause a restriction? How did you manage to route it into your fuel canister? I want to do the Walbro but don't want warranty issues if a CP3 or injectors crap out. I would like to leave the stock lift pump in place and just have to do a quick re-wire and remove a few fittings if need be so the dealer would not even know that an additional pump was on. I have the engine mounted fuel pump...is that what I am missing? On your guy's set-ups do you already have the intank pump? Enquiring minds want to know!

Where exactly did you get this check valve? sounds good! Is it also able to adjust pressure or is it just a restriction to control pressure?
