Hill Pump o-ring sizes to avoid Kit

[orion]

Hi

I know the kit comes with more than just the o-ring, but I'm wondering if anyone has put together the sizes needed to replace all the o-rings on a Hill pump.

O-rings are cheap and these kits are running expensive when adding shipping $50+

My pump is the MK3

Subscribing because I’ve searched this topic before and didn’t have much luck.

A Hill O-ring kit is as much as one of the Chinese pumps and I have two that work just fine. Not spending that kind of money for a few O-rings.

Maybe I'll work on measuring the orings and put this info together
