Pegged fuel pressure gauge

[greenallgreg]

I installed an electronic Isspro 30lb. fuel pressure gauge on my 01. The sender is installed at the airdog. When I installed the gauge I did not use a snubber (wasn't thinking). The gauge worked for a while reading around 12-15lbs of pressure but eventually read 30 lbs and still does today. So I installed a snubber the other day and gauge still reads 30lbs. Is the gauge toast from the pressure spikes or is something else wrong with it?

May need to remove and test on a regulated air supply

Call ISSPRO and ask them how to diagnose the gauge you have. It could be a faulty gauge or the sender.
The only other option you have is to buy a test gauge from Geno's or Vulcan, but you'll need to have a factory test port in place to do that.

I assume the gauge is electric? If so, the senders are either wet or dry. Make sure yours is a wet type. When they gunnysack, they default to 34 psi.

Got it fixed! Turned out to be a bad sender. Thanks everyone!
