Actually, you do have a vacuum pump. Plug your tank vent & run the fuel pump in short bursts. Watch the tank skins closely for cupping between the ribs & watch the fuel line for bubbles. Try smearing the potential leak points on the valve with heavy grease & see if it makes a difference.

No, I wish I did have a vacuum pump. But I can make do with what I've got.

Plan for tomorrow:
Replace line from tank to valve (inspect fuel tank pickup at the same
time) and test.
If no joy, figure out a way to eliminate selector valve (I'm not too
happy at the prospect of not having a fuel shutoff valve, not even for a
bried test flight).

Sounds like Marvin may be onto something with the selector valve idea. Do you have one of those hand pump type vacuum testers (mighty-vac or similar)? If so, how about using it to test the line at various points for leaks. Good luck,
