hey all, the older thermostat housings (EA-ED) have 3 sensors and the EF/EL have 2 and at the moment im using a LPG T piece setup to adapt the water feed to the turbo, but when i looked at my old housing i seen there is a sensor on there i dont need, so if i remove this ill have a direct clean feed from the housing to the turbo but i have no idea on the thread. im looking online for fittings but i need to know what one it is and i cant get the sensor out until i can bolt it down somewhere due to it being soo tight.

can anyone help me out?

3/8 NPT

sweet as. cheers.
