fuel pump questions

[markovr]

I thought that running my tank low was the reason that my pump failled because I did it quite often.When I pulled the pump apart ,the windings were perfect...it was the copper commutator on the armature that had worn right through breaking contact with the brushes at one place.I assume it just wears out in time...as the pump was 250km old...so I suppose any pump this vintage would have this wear and thats just how it is.
There was no noise beforehand it just stopped.

I think you will find with the pump sucking air the RPM of the pump goes off the scale and the pump self destructs inside very quickly.

Mine is also at 250,000 kms with not a noise !

Still original at 9 years!

My VS S2 is still on its original fuel pump. It does not make any strange noises.

Mostly, I fill up once a week in sync with the discount cycle, so the tank does not get low.

However, there was a period of a couple of years (finishing about three years ago) when I regularly ran it fairly low.

Also on trips, I have sometimes also run it very low.

This has not seemed to cause problems for my pump.
