Burner fuel pump drive

[sberry]

I am working on a fuel burner and wondering how or what is the right part listing. It is the burner coupling,,, or fuel pump drive coupling. It had a D on one end about 5/16 and a D coupling on the other about 7/16 or so and it is 4 1/2 long. EHR-SR Wayne burner in a Hotsy washer.
The guy before me had used duct tape to shim the big end, I stepped up a class and used auto body making tape. It needs to be replaced and I see its priced right at the pressure wash parts store. 5 or 6$ but which one is a bit beyond me without extensive research.

#88 nyloflex. should be at any hvac parts house. Will have an assortment of ends and a coupling you cut to fit.

Use new ends and cut lenght to fit.

Thanks, I figured they had a system to it. I didn't measure my motor shaft end which I should have but I was on the phone with the pressure wash store and they guy seemed to be able to get it by burner model. Her said 1/2 end for a Wayne burner, we will see I guess. I was going to have my Bud swing in to supply but now maybe we wait and see.
