Fuel pump issue?
Hi there, I have a 1993 240 that is making a buzzing-grinding noise in the back, I think it's the fuel pump, the noise comes from under there.
My question is, do I have to change the in tank pump too, or the one near the fuel filter would be enough.
Thanks for any advice.

From the FAQ at brickboard.

Fuel Pump Noise.
Fuel Pump Noise.
[Response : Peter James] I would agree the intank pump has failed and you are now stressing the main pump, which in turn can lead to premature failure of the main pump.
[Response :] Are you sure it's the in-tank pump, not the main pump down by the rear wheel arch that is making the noise? Most commonly this pump makes this noise not because it is failing, but because the in tank pump is not supplying the fuel to it for some reason. It won't do it any good to operate in this condition, and when the main pump fails, you're stuck at the roadside. : "
It happens often enough to make it into the FAQ.
Mine only has one pump , but it costs twice as much so theres no savings.
