For a 2001, 110, what would the average running time for the fuel pump after switching on ignition? I’ve had some diffs with the fuel lines of late, requiring replacing the connectors at the tank end and the noise of the pump seems to have been affected. Is the length of running time, in my case nearly a minute, a sign of the fuel pump nearing its end or what I should expect after works on the connectors? Thanks in advance for any info.

Mine runs for about 30 seconds.

What engine have you got. If a TD5 are you hearing the centrifugal oil filter spinning, if it is fuel pump is there any leaks, especially at fuel pressure regulator (a common problem)

Cheers for the response.

It is a TD5. As to the centrifugal oil filter spinning, I couldn’t be sure what that sounds like. Coincidentally, earlier today, I had thought there was an additional (non-engine related) noise while the engine was running but figured it could be everything or anything. There is no obvious signs of leaking from the fuel pump. I wondered if when the replacement connectors were inserted, after a fair degree of resistance to the task, had there positioning , although tight and seemingly secured, made for a little more air entering the system than might be the norm? my worry of course is that at some point in the future, the connections will blow out as they had done before after the pipes had been broken Then badly spliced back on during a welders poor attempt at dropping the fuel tank. That left me high and very dry resulting in a towing back to home.

Before stopping your engine open the bonnet then switch engine off and go to the passenger side of engine near the turbo and listen for a noise like a turbine or motor slowing down, this will be the centrifugal oil filter spinning to a stop, this is normal, (and worrying it is not spinning) is that the noise you are hearing.

Again, thanks for the advice. I’ve not heard anything untoward from the engine bay. Likely I was hearing something rattle underneath when I was trying to suss out the fuel pump noise. Idling is quite quick, or at least quicker than it had been pre-fuel liine connector replacement. So...I would prob need for a good pressure test on the fuel lines to see if it’s an air intake issue. But, it’s more work than I could be fit for. Hopefully, I’ll manage to sort it sooner rather than later.
