SU fuel pumps, in my experience--have several I've rebuilt several times--fail
by becoming intermittent then quitting altogether. Ticking wildly is usually an
air leak or, as someone suggested, a blockage on the inlet side.
If you plan on taking any long road trips do yourself a favor; install an
electronic SU pump, and keep your points pump as a spare (rebuild if
necessary). Moss and others sell the SU electronic, about $140 last I checked.
Well worth it.
You shouldn't spill more than a couple teaspoons of gas when you remove a pump.
Make sure the battery is disconnected to remove any possibility of a spark.

Subject: [Healeys] Fuel Pump
Now that I've come to terms with my SU carbs, I'm turning my attention to
the SU fuel pump. Recently I was driving (65 BJ8) in 90 degree weather.The
car was running smoothly, water temp never over 170. As I coasted to a
light, it just stopped running. The fuel pump was ticking like an angry
hornet. And yes there was plenty of gas in the tank. After a few seconds
it started back up and ran fine the rest of the way home. While I know this
could be any number of things, my working assumption is the fuel pump is
starting to get temperamental. And if I'm wrong, I'm sure it will
eventually. So:
1. Can they/should they be rebuilt or just replaced?
2. Anyone make an electronic version?
3. How much gas will I dump on my garage floor when I change it out?
Sorry if all this seems basic. I finally have the time (recently retired)
and want to begin to take responsibility for the maintenance of this
wonderful automobile.
