loss of fuel pressure??

Everytime I accelerate my fuel pressure drops down to like 50 or 30 and when I put my gut in it, it drips to 0.. bad fuel pump or something else? I have the stock fuel pump in

That's what I'm thinking, I have a walbro but I can't find the right fittings to fit.. idk, might just go dual stockers..

Re: loss of fuel pressure??

I suggest doing the "Hutch" fuel tank mod. I am in process of doing it myself for a low fuel pressure problem. Never know what you'll find when you open up the fuel tank. Getting rid of the mixing chamber makes it worth it! See link below:

Re: loss of fuel pressure??

I would drop the tank and do the intank mods. More then likely thats your issue.

If you have not yet installed the Walbro I would return it and get a Genuine Bosch pump.

I went thru 4 Walbros in as many years. Not worth it...

Re: loss of fuel pressure??

Keep in mind the Walbro is NOT rated for Diesel... And WILL NOT LAST.
