I had a question for some of you CTD guru's. I followed some instructions that I found in the Cummings Forum on how to install an EGT Gauge. It told me to use a 7/16" bit and a 1/4"NPT tap. Well come to find out the fitting that came with my Auto Meter EGT gauge is 1/8".So my question is thiswhere canI get an 1/8" x 1/4"fitting.Im not sure if brass would hold up under those type of temps. Any help here would be appreciated. Thanks

 

Why don't you try out the cummins section, you will have better luck there getting the answer you need.

 

I didn't relize there was a CTD section.
