Fuel pump rebuild

Post by **iddy** » Mon Dec 05, 2005 11:12 am

I've just bought a new pump and I'm considering changing the points and diaphragm on the old one, but having read the car manual it seems a bit daunting (the diaphragm bit).
I know from experience that sometimes it reads worse then it actually is. Is this the case with the pump?

Cheers,

Idris.

It is quite easy. I did it a few months ago with no problems since, But the manual didn't tell me lots of plastic spacers were going to fall out and hide in dark corners in my garage, In fact it took longer to find the last one than to do the job!

Just take your time and follow the instructions to the letter. Once properly set
up it will give you years of trouble free service. I did mine about eight years
ago and it is still fine.

And do it in a plastic basin to catch the spacers ! The diaphragms seem to last for years and years.

Thanks guys.
Slow and steady it is then.

When you take off the old points be sure to count exactly the number of turns and part turns that you need to unscrew them.
Then screw on the new points by exactly the same amount.

NEWAGE..., that would only apply if you are not changing the diaphragm. If
a new diaphragm is being fitted then it would be necessary to do that setting
by rotating the diaphragm itself.

Now I'm getting confused

IDDY, yes, you will be confused unless you have read the instructions in the
workshop manual. Briefly, when a diaphragm is being fitted it is necessary
to adjust it by rotating it until it operates the points throwover mechanism and
then backing it off slightly. This is the all important adjustment for the pump
but is perfectly straightforward when you have the manual in front of you.
