well i put a walbro 255 in today and we had to rig it pretty much and the truck started up but only has 25 psi rail pressure i think one of the hoses in the tank got a lil loose so im hoping that is the problem.

 

i hated my walbro 255, i had nothing but problems with it so i switched back to the stock pump and it works perfect and had plenty of fuel for a cammed 6.0

 

IMO if your not running a crazy huge cam/ Big N20 Shot/ or FI. Just stick with the stock fuel setup and larger injectors.

 

my walbro fuel pump came with fuel hose that is "NOT RATED FOR IN TANK SUBMERSION". lol... Funny though, I dident read it until I found pieces of it in the tank when it busted the 2nd day of having it installed. You may have a small leak in it, causing low psi? idk. Beware of knockoffs, there was an article on knockoff walbros made in china, stamped with walbro logo and all.

-Lurius

 

My Walbro has held 60psi since day one, even wide open at full boost and 60# injectors.... Check your tank connections. I used the stock hose and two stainless clamps. Been holding fine.

 

I, too, used the stock hose and two clamps. Never had a single problem out of mine. I also cut some slats in my bucket so that it would be submerjed all the time in fuel. Has been working for a long time for me.

 

i think yall have a return style system mine is the returnless and i think it had to much psi and blew the hose off so im hoping that is the problem i couldn't use the stock hoses we had to use the one in the kit. im gonna pull the tank again today and see if this is the problem.
