Hi,
In 2017 I got stranded with my 1980 Esprit S2.2 on my way to SPA Francorchamps. The original fuelpomp gave up. Ticking only helped fors ome minutes.
Anyway, I changed the pump wit an original SU fuelpomp with electronics instead of points. I think this is the best solution.
It is the SJ075L0001 from SJsportscars:

The pump is driven by electrical contacts, much like breaker points in a distributor. Over time, they wear down, get oxidized/ burned due to arcing, etc. You should periodically service the points. At the very least, file tem flat and to a nice full face contact. Again, just like in a distributor. Eventually the points get so worn/ burned that you just replace them. On the small, cylindrical end of the pump, there's an end-cap that's held on with a wrap of tape. Remove it. The points are on the end of the pump body/frame.
If you don't mind spending a buck, newer SU pumps are solid state... no points. Just make certain that you getone that has the same flow-rate and output pressure as the Esprit's OEM pump. Excess pressure can cause carb problems.

I often have to hit fuel pump body to get it clicking again so I get car to start when sitting for long time. Is there some kind of maintenance I can perform to fix this?
