[Healeys] Fuel pump

[Kees Oudesluijs]

Most likely an SU AUF301/303/305 pump is fitted as original, the 
Burlen/SU AZX1308 is the equivalent modern replacement. It is very 
unlikely that the pump is scrap. These pumps are imminently rebuildable. 
Probably the points are dirty/burned/worn and need replacement. A 
problem that arises when the car is used sparingly. Replacing the points 
is a simple operation that can be done in about an hour at home using 
basic tools and some feeler gauges..

If a double ended pump is used both ends work simultaneously. If one end 
stops the other end will continue more or less as a back up. This is a 
bit of a problem as you will not normally notice one end stopping.

Even with a new SU pump you often encounter that it does not work 
initially and that you have to remove the cap to clean the points using 
some flower paper.

There are electronic versions but apparently reliability is said to be 
an issue.
