will the stock fuel pump on 87-93 5.0's handle 24lb injectors? i jsut got some and want to put them on, but not sure if the stock fuel pump holds it back

if you have a maf you need to swap it also to one calibrated for 24's and advise swapping pump

if you have enough mods to NEED 24s, then no, the stock pump isnt enough. if you just want to put 24s on because you have them but your motor is mostly stock, the stock pump will be fine.

what makes you think you need 24s?

well i have a gt40 intake, and gt40 iron heads ported and polished, 70mm t/b, 73mm maf...and the car is already running lean. but that may be due to a vac leak. and i just got the injectors, so i was wondering if i should just put them on. but will they work better over the stock 19lb injectors if im using the stock pump still? would there be an advantage?
