Regular gasket material will not work. The material needs to be about 1/8" + thick, gasoline resistance and flexible. Maybe an inter tube?

Looks like you didn’t notice my question. Where did you find the impellers for this motor ? Can anyone else help??

NOS ones come up on Ebay once in a while.

Start a new thread with your question as more people will see it.

Came up with another problem, Fuel valve diaphragm needs to be replaced…The material needs to be about 1/8″ + thick, gasoline resistance and flexible…Trying to come up with a material to make one out of. Any ideas out there????

Something like this might work, but wouldn’t be thick enough if you absolutely had to have 1/8".

The old one is thick, with the springs and metal caps, not sure if a thin material would work. The current one looks like it has a reinforcement material between two pieces of rubber all molded together. I will try something thinner and see what happens.
Thanks for the INFO

202315 diaphragm, this is the old part number. I sure I will not find one and maybe someone else that owned this, had replaced it with this material.
Kinda working in the blind on this. Trial and error :<)

Good morning!

I replaced that valve diaphragm with Viton 60 sheet material I sourced from eBay.

The material came in a 3 pack 6" X 6" X 5/64" (.0781"). 1 piece each of Viton 60, 70 and 90 durometer.

I selected the 60 because it had the flexibility that the diaphragm needed and sealed perfectly.

I have had it installed for several years with out any leaking or other problems.

I don’t remember what I paid for it but it is basically scrap material left over from

some manufacturing process so it wasn’t much.

Hope it helps you!

Respectfully,

Bob

I found this on ebay, hope it will work. VITON FLUOROELASTOMER Disc Rubber Gasket Material.
