[FC] Fuel pump plug

[george koenig]

If you have access to a lathe, take an old fuel pump and machine off the
large diameter end and use the small end as the plug.   This way you can use
the existing "O" ring groove and the set screw. This still leaves a hole in
the center which you can use JB weld to plug it, or  machine a small step in
the top of it and JB weld a penny in it.  You can't buy a plug for less than
a penny.
I would also try hard to remove the plunger. it may be bent.
