Fuel pump issue

[maxwell6]

Hi I could use some help. I have a 2002 gt no fuel pressure at rail at all.When i press Schrader after turning the key i get no pressure at all. Can hear a faint hum from pump but not loading up my rail. So after lowering the tank i see that the tank is a 2003 cobra tank. I need a new pump for about 450 hp supercharged 4.6l 2v with intercooler,kenne bell bap 42lb injectors.Any recommendations on good replacement pumps.Your help would be great. Thanks.

Positive you don't have a Boost a Pump problem or plugged filter? Very odd for both pumps to have crapped out at the same time.
To say I dislike the BAP would be an understatement.

After banging it off the rev limiter a couple of weeks ago.It shut down prior to that cold start was bad would take 2 or three tries then stumble to start. Has new plugs new frps. Would the bap prevent the pump from loading the rail .I can hear the pumps when i turn the key for about 2 seconds then shut off. Also filter is new.

BAP is basically a voltage amplifier. Higher the voltage, faster the pump spins which increases volume. It it's failing, yes possible it's not supplying adequate voltage to properly run the pump(s).

I'm 460 WHP using a single Aeromotive 340 LPH, stock fox lines, Aeromotive regulator, Aermotive fuel rails and 39 lb/hr cobra injector . I would go with the 400 LPH Walboro if I did it again. You can get them on ebay for 100 bucks each. Get the kit. Make sure there the real ones that guys order in bulk.
