proper installation of gauges

Postby spacebetty » Fri Sep 13, 2013 10:41 am

I have a Sunpro water temp gauge I was going to use to measure the temp of the VO coming out of my FPHE. Can I do that, or do I have to buy an oil temp gauge, anyone know?

Also, it's my understanding that in order to work properly any temp gauge sensor has to be completely surrounded by fluid. How does one manage this when installing the sensor on a fuel line?! A t-fitting won't work, according to the instructions, not enough fuel flow. How have you installed your fuel temp gauge?

A water temp guage works fine, thats what I have had for >7 years. Mine is the cheapest guage at the auto parts store.

Mine is in a tee fitting, 1/2" pipe thread, and works great. The end 3/4" of the sender is in the flow. You can see pics of it in the converted vehicles section here.
