the part in the bottom right corner is what I used for my fuel pressure gauge. I think some other places like glacier diesel sells them also

 

You've been having issues though, right? Hope you get it figured out. Otherwise it runs good?

 

Kinda similar to what i used, but it was in 3 pieces. Had the center block with 3 threaded holes, 2 1/2 " fittings on each side and a 1/2" to 3/8" adapter then the fuel hose to the isolator. Couldn't find a one piece tee anywheres so this works fine. No i need to get some wire loom and take care of the wiring

 

yeah thats the problem I ran into also nobody local carried anything so I just bought one online and installed it when it came in

 

I noticed the AD100 pushes about 14-16psi at all times. At wot it moves to 14 but stays there, it won't go any lower. Seems like the Airdog is doing its job! Had to take the gauge back out and teflon tape the threads better, had antifreeze leaking out of it, down the pod and on the floor. At least it wasn't diesel, that would've reeked!
