DonaldSmith Posted September 20, 2009 Report Share Posted September 20, 2009 When my mechanical pump quit, I mounted an electric pump on the right inner fender and wired it to run when the ignition is on. It works fine. But gee, everybody's mounting the electric pump in the rear. Some of the boys rely on the mechanical pump and only use the electric one to refill the fuel bowl after the gas has evaporated after several idle days. I took my manual pump apart, and priced a rebuild kit from Antique Auto Parts Cellar. Only, I also haveto get a price for the big spring, which I broke trying to get the parts apart. So maybe I'll rebuild the old pump, or get a new one from someone like NAPA. In any case, maybe I'll mount the electric pump near the tank. Now, the fuel line has metal tubing running from the gas tank, goes over the axle, and under the left frame just ahead of the spring shackle. Then there's some rubber tubing which goes over an outrigger for the body, and connects to metal tubing that goes along the outside of the frame member. It lookks like the place to mount the fuel pump is behind that outrigger on the outside of the frame. Is that what the guys are doing? Also, is the metal tubing over the axle going to be a big siphon, which will attempt to empty the tank when I disconnect the rubber tubing from it? Any hints?

greg g Posted September 20, 2009 Report Share Posted September 20, 2009 electric pumps work better pushing than they do sucking, which is why most are mounted as ear the tank as practical. As long as the location of the pump is below the level of the gas in the tank the back flow to the tank should't be a problem. Quote Link to comment Share on other sites More sharing options...
oldmopar Posted September 20, 2009 Report Share Posted September 20, 2009 For what its worth I only run a electric pump and have it mounted on the right front inner fender its been a few months and no problems. I also had a 64 W300 (12 volt) with a electric pump mounted in a similar place again no problems. However the instructions with the electrics do say to mount near the tank since the push better then they pull but until I have a problem I am keeping mine on the front fender.

Jerry Roberts Posted September 21, 2009 Report Share Posted September 21, 2009 I have gone through several electric fuel pumps over the years . I used to mount them down low next to the tank but I got tired of crawling under there to test and replace , so now I mount them on the inner fender . As a side note , when using an old choke cable or throttle cable as an auger to clean out the fuel line , I found out that some of the old cables are larger in diameter than others . The cable that I picked up at a flea market was a very good ( large ) fit . Quote Link to comment Share on other sites More sharing options...
grey beard Posted September 21, 2009 Report Share Posted September 21, 2009 I mounted my electric Carter pump close to the tank outlet with a filter between the two. Took my mechanical pump and knocked out the pin on the actuator arm and removed it. Now my old pump is non-operational, and will never leak fuel into the crankcase. It just serves as a hole cover on the side of the block and makes the engine look more original than a billet plate or homemade patch. Works for me . . .

Rollie��� Posted September 21, 2009 Report Share Posted September 21, 2009 (edited) Mounted mine on the outside of the frame rail and yes, when I cut the line it worked like a siphon and tried to empty my tank. I did have a clean catch pan nearby. Like Dave I also took the pin out of the stock fuel pump to make it look original. Also made a block off plate which was probably overkill.

Rollie��� Posted September 21, 2009 Report Share Posted September 21, 2009 Dave, Are you still running fuel through your old pump like I am? Wouldn't fuel still get in to the crankcase if the diaphragm went bad? Just looking out for ya. Quote Link to comment Share on other sites More sharing options...
