Change the fuel filter yesterday. What an awful job that was. The smell of the petrol even in a well ventilated garage was truly terrible.

There were some bits in the petrol but not alot. The inside of the filter didn't look dirty at all.

Disaster - had the same problem on the drive to work. It slowed to nothing, wouldn;t go over 3000 rpm then 1000rpm and died.

No idea what's wrong with it, plenty of fuel.

I had my foot jammed on the accelerator, it would move over 1000rpm.

Could it be a belt?

Belt? no.
Try Mikes suggestions of relay 30, and mine of..
"I agree with JB. Sounds like fuel starvation, and the pump/wiring/relay/fuse are good places to start.
If you remove the rear seat, can you hear the pump while inside the car? I have done that on a B2 80 before."

Are the plugs looking wet/black (form excess fuel-suggesting ignition is dying)or white (from insufficient fuel, suggesting fuel supply problem).
Good luck-and its the weekend now so plenty of time to fix....

I think it's 165 906 381 but I'm having trouble confirming that.

165906381 is correct. The relay in the car may have a different number
