AlanT Posted October 11, 2023 Report Share Posted October 11, 2023 Hi Kelvin. is your car points or electronic ignition? My Spit kept running / appearing to have a good spark but then failing after half a mile or so. Was a crap Chinese condenser. A few £ on one from the Distributor Dr and it’s beautifully smooth. Incidentally, just fixed my neighbours MGA by reverting to good points/condenser after he had similar issues…failed accuspark unit. Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 11, 2023 Report Share Posted October 11, 2023 one very normal place is the short hose off the top of the tank hidden in the boot on all H &V this is often the cause of loose /degraded hose that sucks air and stops the pump suction and could well be the common with both pump failures Pete Link to comment Share on other sites More sharing options...
DanMi Posted October 11, 2023 Report Share Posted October 11, 2023 I would try putting some pipe from the fuel pump inlet into a can of petrol to see if that works which would determine if it is pump or fuel line 1 Link to comment Share on other sites More sharing options...

Sucking by mouth is not to be recommended so one of those little hand pumps like this would be ideal.... Link to comment Share on other sites More sharing options...

Bernard had replaced ALL lines and hoses. Link to comment Share on other sites More sharing options...

The pump has a priming lever though so not needed but that's a useful device there Link to comment Share on other sites More sharing options...
Kelv Posted October 12, 2023 Author Report Share Posted October 12, 2023 Latest update from Bern... "Hi Kelvin, I managed to get a trade price on a battery and when fitted the engine span a lot faster and started using a gravity fed fuel supply. There was an increased voltage of 14.1v across the poles with the engine running. I removed the fuel pump and using an endoscope I could see wear on the cam that operates the pump which could give a slight loss of fuel pump efficiency. I re fitted the fuel pump and fed the pump from a fuel can, there seemed to be a slight improvement. I disconnected all the fuel lines and found that the main steel line was partially blocked, I cleaned it with an airline. I stripped the top of the carb down and removed the float valve and found it to be sticking slightly. I gave everything a good clean and re attached the fuel lines. The engine started and ran well. I will start the engine a few times today and if all is well I will take if for a short run." Link to comment Share on other sites More sharing options...

With a clear leak free pipe once you got fuel flowing it should continue to run freely as a syphon. You should even be able to block the end wait a while and then release it to continue flowing.....

Kelv Posted October 12, 2023 Author Report Share Posted October 12, 2023 (edited) Ah, yes, I understand what you mean now. Yes, that would have diagnosed the issue and possibly cleared out any blockage too. Cheers. I was having a thick moment.
