Just so happened that yesterday I did away with the fuel shut off valve because the new one from Jim Carter's had to be adapted because it had 2 male ends.

Where the original valve had a male end to go into the tank and a female end for the fuel hose to fuel pump line. So I had to buy a double female adapter to connect the fuel hose threaded fitting.

After all that the shut off valve leaked.

Then I ordered a shut off valve and line from Bow Tie Bits. The valve would not fit into the tank and the hose would not fit onto the fuel pump line. I just returned it all back to them.

Down to the old time parts store and I bought two one piece line fittings with a 5/16" x 1" tube end, one with a male thread for the tank and the other female for the steel line and a length of new 5/16" in dia fuel hose.

So this morning I went and measured the steel fuel lines. The outside diameter is .316"

5/16" = .3125"

This truck has 37,000 original miles and was garage kept. With the patina consistent I do not think any of the fuel line were ever changed.
