Fuel System Upgrade
Hello guys,
I have another thread trying to figure out if I have a bad BAP or the BAP killed my stock ls7 pump. Right now, the fuel system set up is stock ls7 pump wired on full time with the Kenne Bell BAP. Secondary A&A fuel system with the pump set up to come on at 4#s of boost. I am thinking I can just upgrade the stock pump in the tank with the secondary fuel system and get rid of the BAP altogether. Then retune. What drop in pump will do the job for me? I am looking to push about 750-800rwhp at the tire at my high elevation of 5200', which corrects to 900+.
Thanks

Why not run the BAP on the external pump. This would leave you with the ability to run a stock pump in the tank. This is the way that A&A recommends to run it. I have a stock pump and bucket for sale if you are interested.

That was another thought. I was going to give A&A a call in the morning. How does the wiring go for that set up? I know the harness is very similar to a racetronic set up.

Twin walbros or twin Aeromotive stealth 340s. Run one as you would a stock pump, wire the second to a HOB switch or BAP (Set at stock voltage NOT the higher voltage) to come on under some set boost level and you should be all set. Y connect the output of both pumps to your fuel line.
