I am getting ready to install the following gauges (EGT, Fuel Pressure, Boost, and Tranny).

My question is what type of sealant, loctite or anti-sieze do you use on the threads?

Tranny Sensor?
Banjo bolts for Boost & Fuel?
Boost & Fuel Sensors?
EGT Sensor?

Thanks

 

I use "Ultra-Black" silicone on all threaded connections near oil or fuel. Clean oil off with brake cleaner and fill the male thread grooves, smooth, install then wipe off excess. Tighten firmly but don't over tighten, it won't be needed.

I've been using silicone in threads for several years now and never a leak. I've had lots of failures with other seals around liquids but never with silicone. Just use a silicone that matches the fluid. I don't like RTV Blue as it isn't as good as black around oil.

Cya

 

Tranny Sensor - Depends on where you put it so need more info
Banjo bolts for Boost & Fuel - Teflon pipe dope
Boost & Fuel Sensors - Teflon pipe dope
EGT Sensor - High temp anti-seize


On the pipe dope, it only takes a very small amount to achieve a quality seal. All surfaces must be clean and dry when the parts are put together.
