how much fuel pressure should a 1999 Isuzu amigo have
the fuel pressure should be 65 pounds of pressure
39 psi +/- 5 psi39 psi +/- 5 psi
40 psi plus or minus 5
30psi
Just a short burst at pressure. It is not so much the volume but the pressure I look for. Fuel pumps are the #1 problem on these models.
the pressure should be between 35 and 42 psi in the fuel rail. It has a valve like the one for air in the tires to measure the fuel pressure.... MOA.
you will need to hook a pressure gauge up to the fuel rail. If the correct pressure is not obtained then the pump is bad. If too much pressure then your fuel pressure regultor is not working. You will need to find out what the normal operating PSI range is for this pump first.
The fuel pressure should be between 40 and 70 psi on a 96 Buick Regal with a 3.8. If the fuel pressure is above 70, then it is to high and should be checked out by a trusted mechanic.
The 4.3L engine in 2002 should have 60 to 66 psi of fuel pressure.
none it runs from the sun
45-65psi
