I need to know the LPH on a stock fuel pump for a 2003 mustang GT. Is the car running a 190LPH fuel pump or a 255LPH fuel pump or what? Thanks. Has anyone delt with a kenne bell boost a pump for fuel pumps? need to know if it works perfectly for 42lb injectors on a supercharged car?

I would say the 255. I looked up replacement parts for your car and one says 60-70GPH (227-265LPH) and the other was 65-75GPH. (246-283LPH)

So I should get a kenne bell boost a pump if thats the case. Need the fuel to flow more cuz like I said its hesitating but the herky jerky went away n 2nd gear and 3rd gear after the 42Lb injectors was installed. Im thinkin that a boost a pump will increase the fuel pump no matter what size it is and you dont even have to drop the tank its all done under the hood and it involves voltage increase to the fuel pump to achieve more flow.

svt focus fuel pump+KB BAP is the way to go fuel wise.

I found this on the web some time back, don't know how accurate it is but it looks authoritative and reasonable.



Keep in mind that the OEM returnless system runs at 40psi.

I ran the Walbro GSS-342HP on my 18psi M62 Miata, I know that sucker can push at least 160lph at 135psi all day...

S.O.B. I should never trust Autozone. #@&$#$%~!!!

Specifying delivery volume (lph, gph, or whatever), without specifying delivery pressure, is gibberish--the two are joined at the hip with regard to defining the performance of any pump, from the one in my fish pond to the one in my Mustang...
