Here's an annoying addition but my pumps always whine. Both were replaced two years ago when they died together, both wired in and checked when they were put on the car (so they're definitely working) and both make a quiet but audible whine when they're running.
They might be broken or they might just be whiney pumps and yes, I'm sure they both work.

I haven't diagnosed it yet, so I don't need the tool for the minute, but it'd be good to see an image of it on this thread. Cheers John |

No idea to be honest. I've only done this on LH injection 240's and ones with a complete standalone engine management. Not done it on K-Jet but in the end a pump is a pump. What it doesn't use it'll return to the tank.

It is the pre-pump in the tank that has died. Put`s extra strain on the main pump especially when the fuel level get`s low. Fairly easy fix.

Same Problem on my S60
I have just developed the same problem on my S60, which is 3 years old and has done just 24,000kms. The whine, which comes and goes, is very loud when outside the car and is only heard when the tank is below half full and the engine is running. When I open the fuel tank cap, there is heavy gas escape and I can hear the fuel inside bubbling vigorously. Problem seems worse in hot weather. My dealer says he hasn't heard of the issue before and seemed surprised when I told him there is discussion on the Volvo Forum about it. Just a bit alarmed that it might explode.
