I took my car in and they said i need to get a new fuel pump. Im not sure which there going to put in, so does anyone have any idea which fuel pump i should buy. Im going to buy a fuel pump my self and then have it installed by my mechanic. I have a 89' Firebird Formula, so if anyone knows which one i should get; something thats not too exp but a good buy with some preformence would be great. Thanks in advace laters

 

no ones going to reply until you give them the year, tpi or carb or tbi, mods. etc.

btw how do you know its the fuel pump??? could be the filter.

 

You can't ever go wrong with a real AC/Delco pump, unless your car has tons of modifications to the motor.

I put in a Borg-Warner pump, from Pep Boys, in '97. Wound up changing it again in '99. Fun!

If we're talking a fuel injected motor here (TBI, I'm guessing?), tell your mech not to re-use the old pulsator. It connects to the fuel pump by o-rings which get dried up over time, crack, and cause fuel leaks (and therefore, low pressure). Either buy a new pulsator for $40, or, tell him to use the short piece of high-pressure fuel line that comes with the pump in place of the pulsator.

The pulsator is there, according to the GM shop manual, to quiet the fuel pump. In '97, I didn't know, and re-used the pulsator. In 99, I used the short piece of hose with "fuel injection hose clamps". (Provide more of a 360 degree seal then regular hose clamps, might be a lie for all I know, but what the heck, why not.) I didn't notice the pump to be any louder.
