I have a '72 1150 L6 motor.
There is only one 1/8" NPT hole in the head cover (approx. between spark plug 3 and 4) but I already have a water temp sending unit installed (extending 1" into the cover) in there.
Others in this forum have suggested cutting and tapping into the "Tell Tale" system but my manual does not talk about it or show it's location. Searching information about the "Tell Tale" system is useless.
I want to drill and tap a 1/8" NPT opening about 1/2" above the existing hole and install a fitting for the Water Pressure hose.
Since the head cover is only there to create a water chamber, and since the fitting wouldn't even extend into the chamber, I don't see any problems.
Has anyone out there successfully installed a Water Pressure gauge using the "Tell Tale" system or my way?
Any advice would be appreciated.
Thanks,
Sporty
