Fuel filter replacement

Good morning.

The fuel filter is along the left frame rail and it has a shield in front the filter that has to be removed. It has four small bolts.

Make sure you bleed off the fuel pressure carefully.

CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber hose clamps.
Ensure that screw does not contact adjacent parts.

WARNING: Before removing fuel filter, release fuel pressure from fuel line.

1. Start engine.
2. Perform "FUEL PRESSURE RELEASE" in "WORK SUP-PORT" mode to release fuel pressure to zero.
3. After engine stalls, crank engine two or three times to make sure that fuel pressure is released.
4. Turn ignition switch "OFF".

I answered your other question and will continue here.

There is no test port for checking the fuel pressure. You will need to test it at the fuel filter. Remove the outlet hose from the filter and attach it to your gauge. If you want to run the engine, then you will need a T fitting to attach it.

With Regulator Vacuum Hose Connected 235 kPa (34 psi)
With Regulator Vacuum Hose Disconnected 294 kPa (43 psi)

Let us know if you have any follow up questions.
