1993 Plymouth Acclaim

Hi:I have a 1993 Plymouth Acclaim.A mechanic checked the fuelpump pressure,and it read 70psi.He said it should only read 40psi. He can't figure out why this is happening.Can anyone tell me why this is happening,and what effects it could be having on my car performance.Is there an adjustment that can cut down on the pressure?Thank you.

Excessive fuel pressure is not good for seals, gaskets, nor the system. It may be a stuck fuel pump. Make sure he is reading in terms of PSI and not KPA or another measurement.

As a mechanic, he should be able to find out why you are getting such high pressures--if indeed you are. A return line could be partially pinched, etc.

Let the mechanic do his job---if he's got the problem right!

There are no adjustments to the fuel system.
