Hey guys, I think my sending unit on my AEM Fuel Pressure gauge went doo-doo on me. Let me know what you guys think:
Before putting in new plugs and fuel filter, key on engine off would read about 44psi. While driving it would give me a slight sway between 37-44psi.
After putting in new plugs and fuel filter KOEO reads 35psi, and while driving will go from 18psi (sometimes) to sway between 25-33psi.
I'm literally reading 10psi lower now, yet when I datalog at idle, reads a steady 39psi on the SCT.
Anyone have issues like this? A new sending unit is $66 and I'm trying to avoid dropping that coin. What I've tried:
-Purging the air from the lines. When I depressurized the fuel system for the filter, I unplugged the inertia switch and cranked it a couple times
-Taking the sending unit and adapter off, re-teflon pasting them, and reinstalling them.
-Checked for vacuum leaks everywhere
The car is running so smooth and has zero drivability issues.
Any help you guys can shoot my way would be awesome. Thanks!
