Hi All

I have had the AA out today as I am not getting fuel delivered to carbs on my CU 2ltr Air cooled.

I have replaced fuel pipes and filter but no luck.

Fuel pump has been off and tested by hand with a line into a jar of fuel and works great.
Ali I can think is that the push rod inside fuel pump is badly worn.

I am going to replace it so can anyone tell me what length it should be and possibly post me a link as to where to buy one that is in stock.

I thought I would change this before I splash out on an electric fuel pump.

Cheers Jay

139.8mm. It could still be the pump the pivot points in the pump wear you can move the arm by hand more than the push rod stroke giving the impression the pump is working. New mechanical pumps are now available again but electric pumps are more efficient.
