Question fuel pump diaphram

I have an old Miller welder/generator, and I need a new fuel pump diaphram.

It's about a 1959 and has opposed 2 cyl 4-stroke aircooled engine.

SN: H152340
Model: AEA ?00?

Sorry, but the name tag is beat-up and I can't read all of the model number.

Miller has no manuals/parts for welders this old.

I cleaned the carb and fired it up on gravity feed (w/o fuel pump) and it runs great.

If someone has a good source for fuel pump parts, I'd like to know!

Thanks, Dan...

I'd have to say that carburetor may be a Walbro.

Walbro is part of TI Automotive now. Try them, maybe they can help you out.

I'd say ANY small engine place should be able to recognize the old parts and offer new replacements.

This is probably a good old work horse and will run like a champ when you straighten it out.

"Ain't" made like that anymore

Talking More Info

Thanks Joe.
And you are right, I think with a bit of TLC this engine will outlast me...

I found a name tag on the engine which should help with finding the fuel pump (not part of the carb, by the way).

I now know I have an Onan Engine.
SN: 109B820920 (I think it's a "B" after the 109, hard to tell).
Model: CCK-S/435L

I Will also see if I can find "Onan" engine parts online.

Sure. Welcome.

Try www.rcpw.com (although their shipping is a bit high).

The information is very good there though .
