Isspro EV2 Fuel Pressure Gauge Jumpy

[MMcConnell]

I intalled a set of Isspro EV2 Gauges (Pyro, Boost, FP, Trans Temp) a couple months ago. I installed the fuel pressure sending unit into a banjo bolt and placed it in the bottom of the factory fuel filter housing. The gauge worked flawlessly. Last weekend I installed a GDP MK-2 + Big Line Kit, since the big line kit replaces the small factory fuel line running from the factory fuel filter housing to the CP3, I had to find a new location to install the fuel pressure sending unit. I used the threaded adapter that came with the MK-2 kit to install the fuel pressure sending unit between the 2 micron filter and the CP3. Following the installation, my fuel pressure gauge now jumps constantly varying from 7 - 9 lbs at idle where it used to stay steady on 9 lbs. Any ideas on why it may be jumpy now while it wasn't before? I took some contact cleaner and cleaned the contact on the sending unit where the electrical connector that goes to the gauge plugs in, but it didnt help. Thanks in advance!

Not sure, mine is the same place as yours and reads about 8 at idle, pretty steady. . It moves a little with load changes.
