min 600 hp fuel pump needed

astar · Aug 26, 2009

I was finally able to get my mustang tuned and running. It is limited to 400 hp because there is not enough fuel upwards from 4000 rpm. I have an additional "piggy back" fuel pump installed which came with the procharger supercharger kit, but it is inadequate.

I want to replace the stock pump and this additional pump with solid single pump. Can someone suggest a good pump to buy ? Once I have enough fuel, the car should have about 550 hp.

I'd do the twin walbro GSL392's. I supported 470 rwhp with just ONE of those pumps. In parallel they are rated to around 800.

They are QUIET and deadly reliable.

I ran mine with a Glenn's sleeper tank, but some people even use them with the in-tank pickup

Yep.

This is an in-line pump ? Correct ?

There is also an in-tank version (GSS340). Which one is best?
The car has a procharger and a 340 hp crate engine with 42 lb injectors. It currently dynoed at 400 hp and 600 torque with the fuel cutting off at around 4000 rpm.

Will the in-tank pump be enough once the car is running at its full potential ? I noticed that both pumps are rated at 255

How much boost are you running?

60lb injectors, GSS340 and a T-Rex.

Done.

odd, i made 560 rwhp with a regular 255 lph and a t-rex

currently i run two pierburgs which are inline style pumps, they are dead quiet and are good for 1000+

i don't have a link other then i can tell you where to buy them. cartech sells a current equivalent to what i have (part # 72165962). they are used on a a lot of turbo / supercharged german cars. i run two in parallel which is supposed to be good to 1200 hp.
