Guest Anonymous Posted June 12, 2003 Share Posted June 12, 2003 Guys, I've got a '76 (non-tii) w/stock mech. fuel pump. When the engine turns over, the pump does not pump fuel. However, after taking the pump off of the head and working it with my hands, it does pump fuel. Does the pushrod that acts on the pump ever go bad? If so, could this be my problem? Thanks, Tim Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 12, 2003 Share Posted June 12, 2003 there are simple testers to see the pump pressure. I have a 74, seems like it doesn't pump too well cause the fuel filter never seems to fill up , but I think that is normal, heard of the rod being too short, youcould probaly do some measurements, with the pump off, see how much throw it has and if then if should be activating the pump properly. If not grind down the spacer, Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 12, 2003 Share Posted June 12, 2003 bears against. The pushrod should have a flat end; as they wear they get beveled. There also should be little or no wear marks on the pad...some aftermarket pumps (notably those made in Italy) have soft metal on the pads and they wear. My pump quit working when the pad had nearly worn through. Too much free play between pad wear and wear on the pushrod. Solution: new pump, or dismantle old pump, weld up pad and grind down smooth. But if the pushrod is beveled, replace it. Hope that's the problem. Cheers Mike Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 12, 2003 Share Posted June 12, 2003 I was swapping mech fuel pumps and took pictures and measurements of 2 different pumps and pushrods. I'd be happy to submit these toward an FAQ on the different combinations. I think there are 3 different pumps. So we'd just need the one more pump's pic and pushrod length.
