Re: Testing Common OMC fuel pumps

[melugin]

I wonder how long the fuel pump will last, whether used or not. The diaphragms were made of flexible material 50-60 years ago, in some cases. This material was not alcohol resistant. I reseal my floats, and use alcohol resistant gaskets, factory/or my own production.
Like the check valve below the carb on pressure systems, the diaphragm material may be the next to go. My most common trouble is on the check valves next to the primer bulb. The new parts seem to give the most trouble.
