Fuel Pressure Isolator question

Call Autometer and ask what the limit of the gauge is.























































I'll save you the trouble. 10% of the sweep is the max. That means a 15psi gauge is only good as long as you don't exceed 1. 5psi over 15 (16. 5psi). After that, it bends the internals and throws off the calibration.



This is why we use a 35psi gauge.

So will diesel fuel hurt isspro guages?

I have been told that it will NOT hurt the Isspro gauges.



Wildcat sells Isspro EV Fuel Pressure gauge kits with no isolators and no problems that I know of FWIW.

You are right Keith, I do need to get a new one, along with a new boost gauge.

But I didnt realize it would screw up the gauge. Thanks.
