Efuel PSI issue

ok, so im having a problem now with psi. With the key on engine off my psi is reading almost 100. With it started and idling it bounces around 60-65. What could cause this? I had a problem a few weeks ago with low psi which was due to a clogged filter.

I don’t know how yours is plumbed, but mine shows a steady 62 psi with the ignition on and with it idling. 60-65 idling is fine. 100psi while running would be too much

What kind of gauge are you using to get the psi #'s ? I had to find your other post to find out what system you have.
