Kohler K301 Fuel Pump Restoration

The diaphragm in this fuel pump for the Kohler I am restoring is kinda hard to find new, so I tried to save it. Here is how I did it. I think it came out great.

That is definitely the thing to rebuild because of the age of the engine that fuel pump is so important to keep the classic Kohler k series engine up and running again

[@AJRestoration]

I agree, and since parts so hard to find.

[@steveferguson1232]

You were able to save this. The amount of corrosion in the fittings and you cleaned it up to working as it should. Great job.

[@AJRestoration]

I was worried for a moment that I would not be able to save it, the corrosion looked quite bad.

Years ago there was a chap in pietermaritzburg that rebuilt diaphragms. Around 1980. He rubberised thin canvas and cooked it in a hot press. Vulcanised

[@AJRestoration]

I wish he was still doing it, I could not find anyone or any spare parts for this one. He could help me out big time.

Evaporust works very good in an ultrasonic cleaner... I see Blackbeard use it often... Good video...

[@AJRestoration]

Ill give it a shot!

[@CharlesManch]

[@AJRestoration]

Like a charm!

[@nineteenandfortyone]

Good job! Works as good as it looks!

[@AJRestoration]

Thank you buddy!

I like glass beads on rubber components. Your repair should last a good long while with the plating.

Thanks for the video, I would have liked to see the valves being cleaned and reinstalled .

Good video thanks

[@AJRestoration]

Thank you very much!

Nice restoration, though I have a few questions. 1 why bother with the pliers if you are getting it with your hands without gloves? And 2 no protection for the housing?

[@AJRestoration]

I tried the pliers first and with a few failed attempts I just used my hands. The solution did not affect the housing, I did a small test before I dunked it in.

[@paulbush7095]

I’m a bit ignorant on how this pump is actuated (as well as many other things). Is the pump lever pushed by the camshaft or something geared to the cam/crank shaft?

[@Failure_Is_An_Option]

Always off the camshaft.

[@paulbush7095]

@@Failure_Is_An_Option thank you for clarifying

[@FishyBoi1337]

I know I've seen it but I couldn't say off the top of my head right now what it's called, but, there's some kinda goop you can buy to basically restore old, hardened rubber like in O-Rings and diaphragms, I'm sure I could find it if I kept searching but I wanna make this comment before I get distracted and forget lmao

[@Failure_Is_An_Option]

Nothing restores rubber.

[@AJRestoration]

Its probably some kind of special silicone. But I have never seen something that can save rubber on the shelves.

[@zanthompson7180]

Not hard to find. eBay
