I am running stage 2 heads cam and all bolt ons, and TNT wet kit. when I hit the juice it is really lean and I need a better fuel system, right now I have a 255 inline pump and it still goes lean. I want to get the racetronix one but ARE is the only place that sells it and they are trying to charge me 500 dollars. Is there any other options?

 

That is the going price for the double in-tank system. These double systems are very labor intensive to manufacture and require many parts to assemble. The wiring harness is very involved but that is what is required to make it a true plug & play system.

If you can not afford the double pump setup you can always install an external pump. Buy the time you buy an EFI pump that can truly handle 800HP at 60PSI+, all the fittings, fuel lines, wiring and heavy labor the $500.00 price tag for the double pump setup starts to sound pretty good. The double in-tank pump module is as easy to install as the factory pump module. The wiring harness plugs into the factory harness so there is no cutting or splicing required. There are no unsightly fuel lines hanging down under your car which can be a potential liability. This system is very quiet.

FYI the Turbo Buick owners pay the same price for their double in-tank systems that are not as involved or as robust as the system Racetronix offers to the LT1 and LS1 f-body owners.

BTW, how much RWHP are you making? Perhaps you only need a single in-tank pump?
If you have the Walbro GSL392 running on 10Ga wire direct to the alternator you should have enough fuel volume to easily support 500-550RWHP. If you kept the factory pump in the tank then this could be chocking the Walbro GSL392.
