in-line elec fuel pump not pushing through mechanical pump

Just a few pictures of the cork gasket, that needs to be replaced.

Here's an update. We removed the fuel line at the carb and yes the electric pump pushes fuel all the way. But ... the regulator just after the electric fuel pump was set to 4. I am thinking that it is very possible that over quite a few "hard starting sessions", we may have blown out that cork gasket.

Since we only plan to use it as a way to prime the system/get fuel into the carb bowl and not use it while running the car, I turned the regulator down to 2. Might be able to turn it down even more.

I know someone who uses Permatex Ultra Gray or Ultra Black as a cork gasket dressing (not globbed on - just a thin smear) in other engine applications to make cork gaskets leak free. Ultra Black claims to hold up to gas and also remain flexible. Not sure if using that might help.

But we did get it started today and gave it a good highway run. When we got back the mechanical fuel pump had a slow but steady drip of fuel that took a few minutes to stop.

Conclusions:
- Spark is ok
- Fuel pumps work
- Carburetor works - might still need cleaning/adjustment, but at least it is not completely shot, or clogged.
- Need to fix the leak at the mechanical fuel bowl glass bowl

Next questions:
- Is it possible to determine visually if the carburetor bowl is empty/dry, or full? What we decided to do now is take the air cleaner off, give the accel pump a shot - if we don't see fuel squirt - we know there is no fuel in the bowl.

I think if we can get the mechanical pump leak fixed and the electric can be used to fill/add fuel to the carb bowl without leaking at the mechanical pump, then we may have at least a temporary solution at hand.

Thinking over the winter we'll take the carb off, fill the bowl and put it over a bucket overnight - then see where the fuel is the next morning.
