Ayuh,... Yer question is sorta hard to fathom,...

In the title, yer askin' 'bout compressed natural gas, 'n in yer post yer askin' 'bout Propane...

Yet, you also say it'll see propane occasionally,...
What's it gonna be runnin' on Normally,..??

All 3 fuels are quite different, 'n the induction systems vary quite abit for each fuel...

In other words,... Alot more Info is needed for any kinda answer....

They are but usally at different psi so you need different regualtor.

Propane can not be used in an engne with gasoline as well. That trick is desiel only. Propane needs a special carb and cant not be blown into the gas carb.

What type of engine for what purpose. A small engine dragster or a pit bike? Kinda left a lot of room in that one. Go kart lawn mower generator golfcart
