sorry whats an isolator

 

Keeps the fuel under the hood and not in the cab. I dont know if this one is compatible but same concept.

Forget the isolator. Given enough time, they will ALL fail. Mine only took about 6 months

Just plumb a regular Fp mechanical FP guage straight to the fuel system. Grease gun hose works well, and use thread sealant.

For a good, cheap gauge, try the mechanical Jeg's 1.5" gauges for <$30. I'm running that now and I wish I would have done it sooner rather than mess with a different setup.

I prefer mechanical fuel pressure gauges:

 

ya i am gunna get one that matches my autometer guages things just gotta match on my truck it has to look good
