need help finding fuel pump

[philly2080]

should a stock 2002 Mustang GT fuel pump hold enough juice for 344hp at the fly? I have cold air, 75mm throttle body and upper plenum, stage 2 cams, under drive pullys, full length headers, x-pipe with cats, mac exauhst, and 4.11 gears. can the fuel pump handle these mods or not? please someone help!!!!! DYNO AT 285 REAR WHEEL HORSE POWER

go with the SVT focus fuel pumps they will be more than enough

i think the stock pump should be fine. he sould be somewhere around 275 rwhp.

need help fining fuel pump

I have a 2002 mustang GT. I have cold air, 75mm throttle body & upper plenum, underdrive pullys, stage 2 cams, full elnght headers, x-pipe with cats, mac exauhst, 4.11 gears and revolution chip. My problem is that i can't get the air fuel ratio on the dyno to go right. it starts at 14.5 an dipps down to 13.2 around 4500 rpms. when we put a fuel guage on it the guage jumps around a little and we think i may need a new fuel pump, but don't know if i need a bigger one. Should the stock pump work, and if not what should i use? Im dynoing at 285hp to the rear wheel. please e-mail me a [email protected] with any thoughts!!! Thanks

It should be fine since saleen hasn't upgraded the fuel pump on the 2000-2004 s281sc.

Stock pump is plenty

you could go with a focus SVT pump. that should be enough for what you are running. In fact the stocker should be more than enough. But if your stocker is getting weak then might as well upgrade to the SVT pump.

BTW you only need to post this in tech we don't need this in both tech and talk. So I merged them for you.

Why? Do it once and be done with it. The focus pump is pretty cheap, check ebay.
