High fuel pressure

[Munch]

When I installed my fuel gauge it read 58lbs every time I turned on the ignition, now today I actually drove it and it reads about 68lbs. When I turn the car on to acc the gauge goes right to 58 but when I start the car it goes to 68lbs.

Any thoughts?

Not even a "hmm, that's strange"?

It's an autometer sending unit and I'd assume it was bad if it didn't read 58 when the ign is turned on.

Guessing voltage difference...try acc. position with jump box attatched or ck. with voltmeter. Just a WAG !

I would simply assume its something in the tune. Running the compressor for A/C is going to put a higher demand on the engine. ???????

Just a guess.
