Fuel Press gauge

[SHobbs]

I need a replacement, preferably a good one. I currently have the Diprocol fuel press. guage with the isolator and the clear tube going into the cab. This is the set up I waited months for due to Diprocol having issues with the isolator. I have fuel in the clear tube coming from the isolator into the cab. The guage will go from 13psi to 30psi whenever I stop say at an atm or a red light and won't come down till I drive it hard or shut the truck down. I'm guessing the guage is shot, is there a guage that can handle the fuel being in it. I want something I can depend on and won't go belly up on me every two years. Any help is appreciated.

Isspro has a fine reputation. I have a one, without and isolator. I also have an isspro oil pressure gauge, plumbed with 1/8 OD compression tubing.

SHobbs,



Your gauge should be OK, your isolator is bad. We have isolators that hold up very well, do you have one of the original tube cylindrical shaped ones? If so that's the problem. Get a new isolator and you should be OK!

Mark, where can I get one and how much. I have heard that the guage was not designed to handle fuel being in it. My isolator is round and looks like you can put a wrench on the ends.
