nah - just a single walbro 255, it sprays out enough fuel for the job. Fuel hat, assembly and wiring are unmolested too. Just plugged in the pump.

What type of aftermarket electrical load does your truck run? You could simply turn off the climate control and radio, amp, lights, Etc and see if the pressure still drops

Also, I don't think a ground would explain it

I'd like someone to build/swap in a 5.0 coyote. That's about the only thing left..we've got the lightning swaps, 5.4 4v swap, BBF build, BBC, and if none of that does it for ya there's a soon to be twin turbo M112 cammed 5.4

What?! Is there a link to a build thread you can give me for the BBF and BBC?

I'm thinking the stock L alternator may not have enough juice to power up all the stuff in my truck, maybe bad ground, or fuel pump wiring is not enough for my pump.

Ideas?
The walbro 342 needs a better feed and ground. I had the same issue with my walbro until I upgraded the wiring with a better relay.

these aren't going in F150's. I was saying certain ppl in here are building these two engines. Granted there is some BS sometimes and off topic crap but for the most part the guys are building engines in this thread granted it takes a while to get results but if we were rich we wouldn't be on here. The side chat is usually something related to engines though.
