fuel leak from mechanical fuel pump

Recently I noticed a gasoline smell from the engine compartment after shutting down the engine, after it had run for an hour or so.

I noticed some fuel on top of the mechanical fuel pump.

I couldn't tell where it was coming from, but replaced the short piece of fuel hose from the fuel pump to the carburetor. This didn't fix the problem.

I've noticed that the leak doesn't happen while the engine is running, and it doesn't happen after shutdown IF I keep the engine compartment blower running and keep the engine compartment door open, till the engine has cooled down.

After several outings, I still haven't had the right timing to see where the fuel is leaking. It either doesn't leak, or it leaks while I'm not watching it.

It seems to leak only about a tablespoon or two, but I know this is still a hazard and needs to be fixed. A couple of times there has been enough to run out of the depressions in the top of the fuel pump and drip down the sides.

Any ideas on the cause and the fix? I'm headed up to the boat tonight and will probably remove the fuel pump to inspect it.

Thanks.
