I'm about to order a Cyberdyne fuel pressure gauge, but I don't know which range to get.

There are two:

0-16 psi
20-100 psi

This of course is for a supercharged V6 4.0L I'm guessing the 0-16 is for carbuerated cars and the 20-100 is for fuel-injected cars.

 

That guess would be correct. You definitely want the higher range gauge.

 

Awesome. Thanks for the reply.

 

No problem. "normal" pressure is 39lbs if memory serves.

 

Hey, would this be ok for an IAT gauge. Cyberdyne's site lists it as an "ambient" air temp gauge. Will it still work??

 

I would certainly think so. I don't see your inlet temp ever exceeding 158 degrees

 

Sweet. I'm just worried about it plugging into the intake tubing. How would it adapt?

 

It depends what the sensor looks like. If it is a simple threaded one just screwing it into an appropriate size hole in the intake tube with a bit of sealer should do. Since it's not under boost, the fitting just needs to be airtight, not mega-strong

 

Hehe, I am under boost. 12psi to be exact.

I think this is what the sensor looks like:
