Default Do you have a noisy fuel pump??

Bought my buddy's 92 SC400:

He owned it for a couple of years. He replaced the fuel pump twice. This last pump has been annoying loud ever since he installed it. I don't mean a loud whine, but terrible cavitating noises.

So I'm at my friends shop this morning swapping out the driveshaft and I just happen to look up and see this:

What...the...F---? It had to be pry'd off with a large screwdriver and who knows how long it's been there. Neither me nor my bud put it there.

It's amazing how much better the car starts and runs and how delightfully quiet the fuel pump is.

So if you have a noisy fuel pump, check for a pair of vice grips on the return line!

LOL, can't say I've ever seen that. Who knows how long that's been starving the car.

No because both pumps we tested and bad. If you'd heard the noise the current one WAS making you'd understand. It was stressed!
