I looked at their website. looks like a good option. I see you have some Autopatrols. We finished rebuilding our Autopatrol 9 and about to finish our 7. We have an 11, but blew the piston and rod out the side the first time we ran it after we got it. Someone had problems with it before. After we picked up all the pieces, we noticed someone had welded on the piston and it cracked at the weld and came apart. If I recall, it's the same engine as a Cat 50 and not very common, so it sits as a static display.

I have used tubing from a air conditioner source with O rings to seal the ends
