Well I have my 87 si that I didn't buy not long ago. Back in December to be exact. The fuel pump is really loud since day one when I bought it and when I turn on a blinker the sound fluctuates up and down as the relay clicks on and off. Any suggestions? Car seems like its driving just fine.
I paint my hood black for that carbon fiber look!!

You wont know for sure since youve only had the car for a while but my hatch, one day i got in it and the fuel pump was extra loud and sounded like it was girgling insted of just humming. It ran like that for almost another year i think. Then literaly one day driving back home i stoped at a friends house, and it wouldnt start again. Diagnosed it as the pump, changed it and it ran great.

If i replaced it should it run quieter? Its not really girggling just really loud like a loud ass water pump.

Could it be a aftermarket pump? Is the car modded at all. I know alot of the aftermarket pumps, like the Walbros and Holley Blues are loud as fuck.

The car hasnt been really modded at allfrom what I can tell besides a cone air filter. So I am really doubting a after market pump.

Out of my 4 si's, they all hum. I hear stopped at idle. I hear the pump frequency oscillate w/ the blinker as well. Unless you hear over the road noise, I agree w/ above and think its okay.

On a related point, does anyone know of an awesome aftermarket fuel pump to replace w/? No more OEM existing. I don't want crap in my car.

Thnx Dave
Keepin' it OEM

The best fuel pump is Bosch. I've used one for 5 years with out problems. It's no toy! It is alot more expensive than a Walbros but you get what you pay for. Price:$199.00

The Bosch Super In-line Pump is the king of all in-line fuel pumps. Is capable of keep high (up to 100 psi constant) fuel pressure under boost without pressure drop-off. This pump keeps fuel pressures rock solid where the little "carter" or "t-rex" pump has failed to keep up. COmes with banjo fittings to convert both ends to slip on barb. This pump can also easily convert to -6 applications handling up to 500 HP applications.

all i have driven has been loud... the oscilin (spellcheck lol) with the tutnsignals lies in the way it is grounded... all in one ground wire.

cut wire on pump, then make a new ground conection your self should do the trick.

i have a B&M pump for an LS1 and it is far louder than any fuel pump on any car i have ever heard. you can insulate the mounts but you still get vibration in the lines. what really quieted it down was adding a regulator after the pump before the cab
Oh, you don't know if it's legal?
you're in california of coarse it's ILLEGAL!!!!!
