Added Quick Open Fuel Valve to Cub fuel line

Postby staninlowerAL » Fri Jul 01, 2016 7:35 pm

My fuel shutoff valve suddenly quit sealing in the closed position. Disassembly and cleaning did not solve the problem and since I wanted to keep the original setup with the inside the tank supplemental filter, I decided to add a quick open valve at the OEM fuel shutoff outlet. Required: 1 ea. 1/8 pipe thread quick open valve and 2 ea 1/8 MIP x 5/16 compression brass fittings. One was rethreaded on the compression side with a 1/2 x 20 bolt die nut to screw directly into the OEM fuel shutoff outlet while the other compression side reconnects the steel fuel line. Take out for the fittings and valve is about 2 inches. Reconnected the threaded connections with PTFE paste sealer, shortened the fuel line to fit and it's good to go. Stan

Stan, I had an original one like yours that would not completely shut off. Bob McCarty and Steve Koons did their magic on it a DSCF. They fixed it so it does not leak down now.

But that being said, I like your solution.

I've found that ball valves handling petroleum fuel tend to start leaking after a while - the plastic bushings tend to soften and wear out faster.

Most fuel valves are a plug or needle valve - they have a more positive mechanical stop to them.

I haven't found that to be the case. Been using ball valves for a positive fuel shut off for years without a problem.

The bushing is constructed from PTFE material which is gasoline resistant.
I have an excuse. CRS.

I have had one on my Cub for over 20 years also. It is still fine.
