OK, I took the advise of all you savy builders and moved my Dukes Fuel Pump from the firewall (outside) , to under my seat. The installation went quite well, xcept that now I need and overflow line to the outside.I am having a terrible time finding the proper fitting. It seems to be smaller than a 1/8 inch pipe thread. Can anyone tell me exactly what they used. Sincerely, Fred N9BF
It's a standard screw thread. I forget the size, but the Dukes has two weep ports 180 degrees apart,, and one should be filled with a set screw. Take it out and match it. I turned some threads on a small piece of brass rod, and drilled it through to make it a pipe that screwed into the appropriate hole. It was only about an inch and a half long. Since the pump is mounted on the belly skin, I just drilled the belly in the appropriate place and stuck the overflow through. (Actually I drilled first, then stuck down the bracket with pump in it) So I "match mounted" the pump to the hole. After that I cut off the the overflow pipe to almost be flush with the skin, keeping a very small angle to prevent air pressurization.
