DESCRIPTION AND OPERATION

The fuel pressure regulator is located in a machined port in the lower part of the housing. The regulator is sealed
in the housing with two ’O’ rings and secured with an internal clip.

The regulator maintains the fuel pump delivery pressure at 4 bar (58 lbf.in

2

). When the fuel pressure exceeds 4

bar (58 lbf.in

2

), the regulator opens and allows fuel to return to the fuel tank via the fuel cooler. The fuel returned

from the regulator is directed back into the fuel filter before being drawn by the high pressure stage of the fuel
pump and directed back to the injectors. A special tool can be attached to the regulator housing fuel feed port and
allows for the fitment of a suitable gauge to measure fuel pump delivery pressure.
