I've gotten some parts from EBay a few times and even went to NAPA and asked the Guy to look in his Old catalog stash as opposed to the computer. I've had several "New" pumps fail because I guess they were too old stock and the diaphragms would break.

Is the old one rebuild-able?

So in the end, I went with a Carter electric and no more problems.


*PUMP LOCATION-I think some one mentioned the fuel pump is located on the top front of the engine mounted up with the arm pointing down looks like.

Thanks Funk
I did the same thing.
NAPA pulled the old hard copy out and showed me where it was discontinued years ago. Thought about taking the arm off and putting it on another pump.
But went with an electric pump.
The old pump is not rebuildable.

And yes, it is mounted on the front, top center of the engine with the 12 inch arm vertical.
