Default Fuel system...

I am wanting to do a fuel system that will properly feed a Procharged (D1SC) 383. I hear the Aeromotive is not too trustworthy when it comes to pumps going out. I heard Magnafuel is the best. I have a 1997 Camaro, so what fuel pump and injectors should I go with? I am going to see what Port Pros can do for me with my motor mods, but I need to know the right pump and what lb. injectors I should use. Thanks!

Are you willing to sump your stock tank or buy an aftermarket tank? If you are it opens up your options for pumps by a long shot. How often does the car see street time?

If you plan on keeping the stock housing setup you could run dual Walbro 255s or Dual Bosch 420s. Both are pretty similar pumps.

If you plan on sumping your setup you will have to many choices to name. Some of them are Bosch 420Ls, MagnaFuel 4301/4302s and if your limited street the A1000 is a simple easy choice for a track car.

Hope this helped, Good Luck

Tony.

Here's how mine is currently setup... Works like a charm too.

Sumped stock tank
-10an feed
Aeromotive Eliminator pump
-8an line to front
Aeroquip Y-block feeding each rail
Aeromotive A-1000-6 regulator (-6an inlets and outlets)
-6an from regulator to stock tank sender (actually stock pressure port)
75lb/hr injectors

Had no problems supplying the fuel to my car on the dyno. And the street/track tuning is under way.

FWIW, I know lots of people who run Aeromotive pumps without a problem. Besides that, they are the only ones who are willing to publish flow data on there pumps, which says alot to me.
