I have an ISSPRO Fuel Pressure gauge setup (from Piers ,thx, guys, great service!) ready to install, and in searching the various forums, it seems that the overwhelming majority believe that the isolator is either unnecessary or a weak link in the system;
Is this because the diesel fuel will eat the diaphragm?
Is the gauge "diesel proof"?
Will running fuel directly to the gauge going to void any warranty coverage from ISSPRO?

Thoughts / comments welcome!

Thx / CMR

 

Going on 3 years, never dripped a single drop.

Quality parts make for a quality job that you only do once.

 

Those gauges are made for diesel use. The diesel will not bother them a bit.
