The required fuel pressure varies from year, make, model and engine size. An example would be, a 2000 Chevrolet Blazer with the 4.3L engine would require 60 to 66 psi for the fuel system to operate correctly. Any more or less than that the engine would run poorly if at all.
High
high pressure fuel pump is mounted on the frame on the drivers side. low pressure is in the fuel tank
low fuel pressure
There is a low pressure fuel pump in each fuel tank. The low pressure pump feeds the inline high pressure pump. Newer models , I believe 1990 and up, changed to the high pressure in tank fuel pump and eliminated the in line pump.
you should have 2pumps, a low pressure in the tnk and a high pressure in the line.
A fluid will move from high pressure to low pressure.
If it is a 2.7 L diesel, the first is in the fuel tank, the low and high pressure pumps are at the front of the engine high up, the high pressure pump feeds the common rail. The filter is to the rear of the near side of the engine easily visable and is between the pump in the tank and the low pressure pump in the fuel circuit. fuel pressure is very high so take great care.
There is a low pressure fuel pump in the gas tank, and a high pressure in-line fuel pump located on the under-carriage beneath the drivers seat
fuel tanks there is a low pressure fuel pump in each tank, and a high pressure on in frame rail on drivers side after fuel filter.
p1130 is fuel system pressure failure. check fuel pump (low pressure) under car, fuel filter for restrictions, perform backleak test injectors, test high pressure fuel pump and solenoids and high pressure sensor on fuel rail.
fuel pressure on non-turbo 64-85psi .65 ltr of fuel in 30 seconds turbo 71-92psi 1.10 ltr of fuel in 30seconds
