Turbo 4.8 fueling.... Return or returnless and other questions.
So I nabbed a good deal on some 1650 FIC injectors and I'm piecing together my turbo components.... I've been looking at the on3 return system, it seems like a good price but I can't find any reviews on it. Do y'all think that that would be a smart way to go? Can I install a return fuel system on the truck and not have to return? Any other fuel system advice would be appreciated. Truck is an 03.

If there is another good return kit, I'm all ears.

Well, I guess while I have an audience, are stock rails alright or do I need to figure something out to mount a regulator to them or just do a custom rail setup? I can't find anything 100% bolt up except for some on eBay and the crossover was -6 which is pretty small. I'm looking at stock block 4.8 with gen 3 rods for right now.

With the stock rails you can make them work but the fpr would have to be before the rails which idk if that’s the way you want it. I’ve heard and seen the fpr after rails towards the front of the intake. I’m going return style pretty soon as well but I have after market Holley rails I’m going make work with the shaved gen 3 intake. But the fpr will be after rails like most. Just look at the Holley kits and Edelbrocks and see how they set it up. But I’ve seen the fpr before rails but I think the fpr after the rails it controls the psi then excess back to the tank. That’s the info I’ve gathered

I’d just get new rails honestly looks way better run some nice fittings 3/8 push lock to -8an or whatever size your running I’ve seen -8 mostly for return and just run a new feed line to a y splitter then off to each rail then to the fpr and back home. That’s my route. Looks good too
