I'm going to replace the original '74 3 port fuel pump with a '75-76 2 port model in the original stock location on the body under the R/S engine tin. As long as the flow rate and the operating pressure are sufficient, are there any operational problems putting it there?? How about mounting??
I know these pumps "push" fuel better than suction, but I don't want to relocate it to the front trunk. (I'm also trying to avoid buying a China rebuilt 3 port.) All help appreciated. Paul |

I've heard the vapor lock claim, and have yet to see/hear anyone complaining of a rear mounted pump vapor locking. I also see a lot of very old 3-port pumps working just fine. If I were shopping for a replacement pump, I would get a used 3-port before I retrofitted a 2-port into the back.

Actually had a '73 completely shut down at 60 mph on a hot summer afternoon some years back. Pulled to the side of the road and it just cranked. Got towed to a shop and a few hours later (cooled down), it started right up. Vapor lock??? Who knows. Anyway, any particular reason why you would stay with a 3 port instead of going to a 2 port?

Paul Nope, no reason at all to stay with the early pump, IMO. While using a used 3 port pump is OK, IF you can find a good one, there are lots of 75 and up VW bugs and busses still on their original 2 port pump. The Cap'n |
