I use all Isspro EV2's in my pickup, but I've been having issues with the fuel pressure gauge. Some times it just reads a bit high, other times it pegs the needle at 40psi- even with 0psi at the sensor. I run an Airdog 150 and have the sender tapped into the elbow at my CP3. I feel that it's at 18-20psi- normally. Any ideas what could be wrong? The gauge lights up and dims correctly, but the readings get off fairly often.
