Need help.. I just received my pyro gauge in the mail and really want to get it installed this weekend. My problem is I don't know what size tap to use with the fitting. I plan on placing it pre turbo and I don't want to mess up my exhaust manifold. It the autometer series ultralite. If anyone has installed this pre turbo please help


2004.5 Black 3500 SRW 4X4

 

Depends on the probe size...most likely either a 1/4" or 1/8" NPT tap. It will be easy to see the difference. Bring the probe to the hardware shop and find out.

 

Maybe this thread could help you out.
