Hi Everyone
Trying to establish if we have a fuel pump problem and also what fuel pump we need to replace it with, read on and you'll see what I mean.
When out driving recently the engine started stuttering and then it would pick up again.
Having recently had the fuel tank off to replace the tube from the filler cap to the tank and repair a leak we took it all off again to ensure no blockages from tank to carb (filter etc), all now clean.
Suspect that the fuel pump might not be pumping efficiently as the fuel filter seems to empty quicker than I would expect whilst the engine is running.
So, on to the fuel pump. Fitted is a Sofabex and therefore not a standard part. It is fully sealed so cannot take apart for inspection.
The sofabex pump seems to be operated by a rod which goes between the fuel pump and the engine making the pumping action.
It has an inlet, outlet and pipe to the carb.
Questions:
1) Anyone any experience of this potential fuel starvation issue?
2) What is the correct fuel pump for this engine - 1108cc?
Have attached a photo of the Sofabex type of pump and engine
All help gratefully received
