I just bought a rebuilt P7100 pump for my 12v and took it to a mechanic last monday to get it put on. He put it on but cannot get it to keep running. He says that air is getting in the line somewhere. He has been checking the fuel system and today he manually pumped fuel from a can directly to the inj. pump. So far, still no luck. He will pump it up but can't keep it running. He said that it has to be either the pump itself of some seals at the injectors. Has any one had a strange air leak like this? I really need to get this pickup out of the shop as soon as I can. Thanks
