Re:
I had a problem with the fuel pump, well I thought it was, on my kitcar with the 2l Fiat Twincam with twin Dellortos.
It would randomly run badly then cut out, would start after a few minutes only for fault to re-occur and soon realised it was fuel delivery. Checked the pump and found the guy who built it had fitted a high pressure fuel injection pump without a fuel pressure regulator. So I replaced it with a SU electric pump I got from my brother. Same fault kept on happening but I then wrongly thought because it was an old pump it was the pump. Tried several but then eventually bought a brand new Facet solid state pump. Same effin problem.
Had already, at start of problem, looked in petrol tank through the fuel level sensor hole but couldn't see anything that could be blocking fuel pick-up pipe. Couldn't see the actual pick-up pipe as there was a baffle, to prevent fuel surge, at end of tank. So, in desperation, drilled a circle of holes in top of tank above fuel pick-up pipe so that I could see inside.
What did I find? Several bits of brown card that when retrieved and put back together was a label/ticket 30mm by 60mm with a name written on it. The name of the guy who'd welded the tank together. Wanker. It had been in there for about 5 years before it gradually broke up to be sucked against fuel pick-up pipe stopping fuel delivery.
