I have a 30 roadster on 32 frame rails with a 57 312 yblock with ECZ-G heads. The last couple of weeks I have been installing a 1941 Ford dash which has beeen a challenge on many levels. I want to use the stock 6 volt gauges with my 12 volt system. I have installed a voltage reducer for the gauges. All was going well until I tried to install a 6 volt sensor and found the hole is smaller. I have been running a mechanical Stewart Warner gauge. Do I need a 6 volt sensor and what sensor will fit? Thanks for the help
 
You may want to check a sensor for a 54 or 55 Ford Y block as they were six volt. When you start the engine the first time, try to have a hand held temp sensor handy to check the electric gage. The hand held infra red sensors are also handy for finding a bad cylinder, as a cool exhaust isnt working as hard as the hot ones.
 
thanks for the reply. I have a Yblock removed from a 55 f100 I takes the same diameter sensor as single pole flathead. Thanks again
 
You will nead the bushing from the earlier head. If you no longer have access to it new ones are available from any Thunderbird supply shop.
 
I think you might have to redrill the head for the sending unit but another option is the 80s trucks had ported vacumn switches on a part that the heater hose attached that screwed in the intake so that might work in your situation.
