Ford 302 - attaching 3 water temp sensors...but only 1 port?

[MetalManiac]

Hi folks, working on my Gen3 with a 1987 Ford 302, I need to install 3 separate sensors into the coolant flow
1) Holley Sniper sensor
2) Dash gauge sensor
3) Thermostat sensor (included in kit)


But I seem to only have 1 port on the motor for this.
Holley says not to tee the sensor and others have reported doing so will cause low readings outside the flow stream.

Any ideas? Thanks,

I don’t have a ford, but if I have to with my LS I’ll tap the water pump. I think they’re usually 1/8 NPt, can’t remember.

You don't need the thermostatic sensor from the kit if you just use the Sniper to control the fan. There are fittings that you can use in the manifold heater port that will provide a port for the second CTS while still letting you plumb the heater.

Here is another option that gives you a port for the temp sensor (includes a ground wire connection) in-line with your heater hose.
