maybe a dumb question help needed

8850d · January 31st, 2013, 10:24 PM

I had a form I added about the BBK mass air flow and 24 lb injecters I am now wondering if I need to upgrade the fuel pump to run the 24's or is the stock good enough I know I would rether have bigger and not need it or need it and not have it I know the 93 cobra ran 24's but was it the stock fuel pump or was it bigger 225lp?

Why other mods do you have? The injectors won't over tax the pump until the engine/ECM asks them to. If you have stock heads I think you are ok. But a 255lph definitely won't hurt

Hes right and if i were you try and stay away from fuel a lot of stuff can go bad but you should be fine

I ran 24 lb injectors with the stock fuel pump for years but my modd list wasnt that big at the time. I think a 255 lph pump is always a good idea though.

I just saw one of your old threads about the heater vacuum lines. Im sure you have fixed the problem by now but incase you havent, let me know cuz my dash is out right now and i can take some pictures for you.

I need to check and see what size fuel pump is in my car. Is the stock one too small for my pos?
