Water pressure gauge

[Bigchris090]

I was hoping someone could point me in the right direction with fitting a water pressure gauge, will the pipe/sender screw into the block using the bolt in this picture?


Also, I have a two piece exhaust plate (I think) on the port side is an elbow and hose. What should this be connected to?

Any help much appreciated. Chris

I believe that hose t into ur tell tale

I was thinking that. Currently doesn't have a tell tale just water discharge from the port thermostat? Should I pipe this to exhaust plate with a tee for tell tale?

The gauge arrived with an 1/8th npt male adapter for the block. The bolt that's in looks larger. Does anyone know what thread they are?

Not sure of thread but u should b abke to find rite parts to adapt down or find sumthin like this

The cooling system is now plumbed in with all new rubber hoses. I went to remove the thermostats however the bolts feel tight. olne on each side as it happens feels reluctant to undo.
I didn't try hard, it's a very old engine... don't really want the trouble of extracting snapped bolts etc

do i run it as is? When started water flows from stats straight away...
