I inadvertently ran my (1974?) MF135 with the fuel tap shut off. It ran for a while, then stopped from lack of fuel -- obviously! I have bled the system and plenty of fuel is coming out of the vent screws on the CAV injector pump but the engine won't fire up. It usually starts up on the first turn of the key. There is plenty of information on the Internet, in fact far too much! But, assuming it is the pump, how difficult to repair myself? I'm guessing, running dry may have bust a seal. Haven't checked to see if fuel is coming out at the injectors yet but after doing a quick search on here it seemed the sensible thing to do was consult the experts! So, what do I do next? I gather a specialist will want a few hundred to repair.
