[Healeys] Fuel pumps (AGAIN!)

Wed Nov 28 15:13:37 MST 2018

Quite so. The only thing I can come up with is the car is hardly being 
used and being stored in dampish non ventilated conditions, thus 
corroding the points. As I said before I have had SU fuel pumps in from 
more than 50 years old which were absolutely perfect except for the 
points corroded because the car was not used enough or worn because of 
not being adjusted properly.

If used regularly and kept dry internally they last forever.

Another thing: If you have had to tap the pump to get it going, 
replace/polish and adjust the points ASAP. Do not wait until you have to 
repeat the tapping.

When fitting a new SU-pump you best remove the cap to inspect and if 
needed clean the points first with very fine polishing paper, I use at 
least 1000. It is even not uncommon that brand new pumps that have been 
on the shelf for a while, either at home, in the garage or at the 
suppliers do not work because the points are dirty/corroded and have to 
be attended to first. I have bought many pumps that were sold as 
"defective, for spares or repair" for a song, that did not work and 
appeared to be in fact NOS. Cleaning and polishing the points was all 
that was needed for these. If you have a new/rebuild spare pump in store 
, remove the cap and insert a bit of acid free paper in between the 
points, this will stop electrolytic corrosion.

In the late 70´s I was collecting  quite a lot of Jensen parts and got 
presented a new pump by Jensen Parts & Service that was said to be 
defective but only needed some small attention. My old pump kept working 
(more than 160000mls) so the new pump was never needed. About 5 or 6 
years ago I came across that pump and decided to have a look inside. It 
was of course mint but there were real cauliflowers around the points. 
Just polished them, fitted a transil (as I do with all my rebuilds) and 
is now in my present car.
