C5 1400fwhp fuel system.
I need a 1400-1500fwhp fuel system for a 2002 c5 any help. Whats better twin pumps in tank or external. Prices all the usual. Im looking for over 1000rwhp through a powerglide.

I would think a stump tank with an external or two. 1400rwhp sounds like an FI car.
I have seen people wire two pumps so that one is always on and the second one comes on at XX boost level.

run triple in tanks like the supra guys. tiago and mecham run them, and it works. if your FI and have an eboost2 you wire up the third to the extra aux port. fwiw tiago is running a 427 lsx with twin 76's and mecham is running a tti race kit with an 88mm i think

Here is what I used on my C5. It's a custom setup that runs a single 255lph intank pump under normal driving conditions and kicks the Aeromotive A1000 on under boost with a hob switch. It's enough fuel to support over 1500hp and have great street drivablity. It also keeps the factory jet siphon opperating so both tanks work!

i think twin walbros intank to y'ed together to a 420 bosch pump would get you to 1400fwhp. im going to try it here in the next month,
or
twin walbros to twin 420s, -1 walbro feed to a 420 , then y them both together at a -10 line, basically twin 340s and twin 420s, have one side on all the time and the other relay hooked up to the boost switch. that will move 1400hp worth all day.

Magnafuel MP-4303 with a -10 feed to a y up front and -8 to to each rail will support what you want. One external pump to come on only in boost triggered by a hobbs switch which will be reliable and quiet when in normal driving conditions, simple and effective.
