All-

I'm working on my Procharged 383 setup, and looking into fuel system upgrades. I know I'm going to go with dual in-tank 255's, #85 -ish injectors, Speed inc. braided stainless line kit, and plumb the rails parallel. I have a few questions:

1) What modifications need to be made to the rails to be able to plumb them in parallel (a Y coming out of my FPR, one line to each rail)?
2) What size AN fitting should be on the rails for my setup?
3) Do I need to consider anything else?

Thanks-

I'm getting a LOT closer to the build being underway, and I still need some info on this....

How much power are you looking to make. stock lines/setup should be good to 700+ RWHP as proven before. If you're going for a decent amount more, -8 in and -6 out of each side in parallel would work. FYI I'm getting ready to finish a 383/T76 turbo setup and will be starting with stock lines and upgrading IF, and that's IF, necessary.

Good call. Then I won't do anything with them for now, and I'll see what happens.

Fastbird knows whats up,,,go -8 lines,,and you can run them in series..in theory parallel seems to push more flow.but you can achieve proper flow in series..just throwing it at you,,save a bit of cash on lines,fittings and a dis block
