in-line elec fuel pump not pushing through mechanical pump

[Merc Cruzer]

I have a electric fuel pump in my system and don't use a fuel regulator.

It is easy to remove the glass fuel bowl and inspect the cork gasket. Just put a towel or rag under the glass bowl and loosen it, and carefully remove it from the pump. Then carefully remove the the cork gasket. It may come out in pieces and if so then just replace it, because no matter what you do it will continue to leak.

There is no way to see how full the float bowl of the cab is unless you take the top off the carburetor. You are correct is saying that if the carburetor squirts gas when you pump it, then there is gas in the float bowel.

As to inspecting the fuel valves in the pump, as an FYI, I have attached a few pictures of the 53' Mercury dual action pump. I recently (in the last two weeks) rebuilt two fuel pumps for my car. One to serve as a back up.
