Looking for diaphragm material.

[Tremel]

Where can I find diaphragm material for repairing a fuel pump? This is for my Kohler Generator.

Hi Bill-
I have some fresh 1/16" Buna N fuel pump material with nylon reinforcing mesh here to cut these diaphraghms from. I have the die to do the AC pump for the F-12 IHC which is the same as many other applications. These are approx 3" OD with six holes spaced around the outside and one hole in the middle. It is probably what you are looking for. Call or email for more information.
Thank you,

Bill,
What model Kohler generator is that??

Dave,
My Kohler 800 has a Briggs Model B engine with and A-C fuel pump Model 3637. A friend has the same setup with an A-C Model 8344 fuel pump. Do you think your diaphrams will fit them??

Bill,
I had the same problem with an AC pump for my Kohler light plant. A gentleman on this site responded and sold me the diaphram for about a buck, but when it arrived it was way too big! I simply trimmed it down and repunched the screw holes.....not hard and it works perfectly. I'd just get the material that Ed offers rather than hunt the whole country for an original.

Oops! I meant buy the material that DAVE REED sells! Sorry...it's early in the morning here. Best, George

Dave, thanks for your reply. I'll drop you a line in a few and get some of the material from you.

The pump doesn't look like a typical AC pump. It's a little different. I have photos of the engine on the SparksArcs website. You can kinda see the fuel pump.

The engine is a model 3E22. It runs like a top now and All I need to do is excite the coils and I'll be good to go.

Got the gasket material yesterday. Thanks Dave.

The good news is that they will fit. The bad news is that the pump is in pretty bad shape. The plunger was made of brass and was broke. Also, the external primer lever was also broke (I knew that). So, with these parts broken, I need to hunt down a new pump.

Any clue. It is indeed an AC fuel pump. There are NO numbers on this thing.
