Hello Everyone.

Can somebody tell me why there is a water spout directly above the top sparkplug? Looks like a hose is needed to go somewhere or can I just cover it?

Water pressure tube to gauge.

Yes, you can plug it if you're not using a dash mounted water pressure gage. You can replace the fitting with the correct brass pipe plug with some thread sealant or just put a automotive vacuum hose plug over it with a zip tie.

Thank you for the responses. I will try to connect the guage but will most likely just cover it.
