I have a manual a c type fuel pump.
It displays an intermittent fault when it fails to pump fuel into carb.
Basically, when I operate the priming lever, no fuel gets pumped into carb, but (using a temporary one pint tank) I can see and hear air bubbles being pumped INTO tank.
This seems to suggest a problem with one of valves.
If I then remove outlet pipe from carb and operate priming lever, after a few seconds pump begins to pump out of Outlet (carb) pipe correctly and no bubbles into fuel tank.
Start engine, runs fine.
Anyone any idea what the problem might be.....I don't want to trust the pump on the car on a run just yet.
