In Reply to: O12 fuel pump posted by JeffinWa on October 22, 2007 at 19:40:07:

[quote="JeffinWa"](quoted from post at 19:40:07 10/22/07) I purchased an O12 that has not been running for 8 years. First thing I noticed was no gas in the tank or the filter bowl. When I put some in, after cleaning the bowl, the pump would not. When I took the pump apart the diaphram was too stiff to move. I flexed its edges and gradually got it to be a little more pliable. Now it moves a little air, kind of a snorting sound, when I push on the pump lever where the rod from the block whould normally push on. When I bolt it back on the block a few drops of gas do come out the output which is better than the nothing before. Still not much better though. Anyone have any hints about this or an idea where I can get a replacement diaphram or whole pump? After that I have to see why she's not sparking. But I haven't peeked at the points yet. Thanks in advance for the help![/quote

There are at least two diaphram scenarios in that fuel pump. It has been too long since I had one of those apart but one has the diaphram that comes out separatley and the other is a component part, I think it is attached to the plunger and conot be separated from it. Discribe yours to Gordon and he will set you up I am sure.
