So I have a returnless stock fuel system with 44lb injectors. I am running 8psi with a p1sc procharger. What can I do with a returnless system? If going with a walbro or bosch, those all need to be setup as return style right? Would i need to add a check valve? I have been using the hell out of the search but can't come up with a definate answer.

If I ever went to return setup, could I use the factory feed line as the return? Just trying to find the best but cost effective way to make sure I have the fuel this engine needs. She's a daily driver so keep that in mind. Thanks.

You dont need to convert to return just yet. You can run a walbro in the stock bucket. moregrip is selling the magnacharger walbro kit that is a complete replacement for your truck.

I am running the same walbro pump on my returnless system making 510rwhp.

Now are you using the stock wiring or a 10-12 ga kit with a relay? Will that pump have priming issues? Aka... need a check valve? Or be ok as is? Sorry for all the questions... only want to do this once.

a single walbro 255 can support like 600 hp

The pump should have a built in check valve. Mine works like stock and i don't have a relay. I just took apart the stock connector and reconnected the walbro connector so that i wouldn't have to splice any wires.

That's badass! I don't like splicing into the factory stuff either. Makes for a nice clean install when all done. I sent a pm for the pump. Thanks for finding it. I plan to throw in that pump then head to the Dyno.

If you wait a few months aeromotive is coming out with replacement drop in pump that out flows the Walbro 255 ....look it up 340 Stealth pump Aeromotive...

They're pretty impressive and should be available by the beginning of February.

I'll wait until they have been on the road for a while... right now there are no opinions or real world tests from guys like us! Plus I don't think my truck will need more fuel than the walbro. But it does look good. Too bad she will be hidden within the fuel tank.
