Ordered a 3/4" Bypass Tee (without brass barbed fitting) yesterday that's part of the Thermo-Bob kit to replace the original thermostat housing. It already has 1/4" pipe threads installed for the brass barbed fitting.
Going to use a 1/4" pipe to 1/8" pipe bushing threaded directly into the 3/4" Bypass Tee for the original temp indicator sender to thread into. Found the OEM sender is 1/8" pipe thread.
Working on other parts of the Cafe project right now, so will be a little while before posting photos of Thermo-Bob unit with bypass tee replacing thermostat housing installed.
Believe I will need to connect a ground wire to the fitting to make the sending unit work.
3/4" Bypass Tee installed at the lower radiator outlet. Will use this fitting to replace the thermostat housing:
Thermo-Bob & original thermostat housing plumbing:
1/4" to 1/8" pipe bushing will thread into Bypass Tee so OEM temp sender can thread into bushing:
