there is two open holes in the front of my stealthram that i need to plug (not running a heater at the moment) does anyone know what size they are?

i also need to know what size the heater hose hole on my stewart stage II waterpump is

and what size is the little plug on the back of the china wall on a roller block

The HSR is a 1/2 NPT thread size pipe plug. The water pump probably is too.

China wall oil port is 1/8" npt.

thanks everyone!

jsut got to find a 1/8 plug now...

Put your oil pressure switch there and you won't have to plug it

then ill just have to plug the one by the oil filter...
