[Healeys] Fuel pumps (AGAIN!)

[Kees Oudesluijs]

50% humidity should be all it needs for storing. Perfect. However I 
would first inspect, clean and adjust the points before storing the 
spare pump (with some acid free paper between the points). Depending on 
how often you drive the car, not so much the distance, I would inspect 
and if needed clean the points once every year on the fitted pump and 
check the spare pump for working. I must confess that I have never 
checked the pump since I fitted it after I serviced it (cleaning the 
points and fitting a transil was all it needed) years ago. I also carry 
a spare in the boot but it is not really needed as the pump is easily 
accessible next to the petrol tank in the boot and can be serviced 
within minutes.

Rebuild pumps are relatively cheap at between €80 and €120. Used pumps 
can be found for less than €10 but usually need a service or rebuild, 
and if you are lucky only a clean, polish and adjustment of the points. 
The old diaphragms are near indestructible and only need loosening and a 
bit of talcum powder in between the three layers. They are much better 
than later single layer replacements.
