[6pack] Moss replica fuel pump vs. original AC - what I found

[Bruce Simms]

The Moss pump failed in service
The rubber valve seals don't fit right.  too
skinny.   I found one when I took the pump top cover off.  The AC seals fit
right.
The tang one the end of the diaphragm shaft is not the same as the one
on the original pump.  Maybe my tang was broken, but, it wouldn't engage
properly with the pin.
The Moss shaft has a decent looking oil seal on it.  No
oil seal on original shaft.
 
I rebuilt my AC pump with the TRF kit.   It 
proved reliable on a drive yesterday.   TRF provides oil seals for their
diaphragm shaft, but not the oil seal retainer cup shown in the kit picture.  
Dave H. said they can't get them.
 
If I could get the Moss rubber diaphragm
onto the original AC pump shaft, I could use it in the Moss pump and
likely make it reliable.    An original rebuild kit would also likely do the
trick.   I don't think they sell individual pump parts.
