Motor home parts
We had purchased this motor home last year. I had filled it up with fuel, when I had gone to the back side I could smell gas, later on I saw fuel stains on the frame and behind the frame was a fuel regulator and that was leaking. all I needed was a diaphragm and you people had what I needed. And I thank you so much, it works just fine. I'm going to keep you in mind if there's anything else I need Bernie

Holley Regulator Diaphragm
I keep a couple on hand in my tool box. I just replace them so often even if not broken. These are spare parts.

My 30 year old pressure regulator started leaking. Bought this rebuild kit and it was an exact match to the old stuff......no more leaks!
