Propane Fuel Filter Replacement
REMOVAL
1. Relieve propane fuel system pressure. Refer to Propane
Fuel System Pressure Relief.
2. Disconnect the negative battery cable.
3. Slowly loosen the filter housing retaining bolt and
remove it.
4. Pull filter housing from electric lock off assembly.
5. Locate and remove filter magnet.
6. Remove the filter from housing.
7. Remove and discard housing seal.
8. Remove and discard retaining bolt seal.
9. Remove and discard mounting plate to lock off O-ring
seal.
INSTALLATION
REINSTALL FILTER MAGNET IN HOUSING BEFORE INSTALLING NEW SEAL.
1. Install mounting plate to lock off O-ring seal.
2. Install retaining bolt seal.
3. Install housing seal.
4. Drop magnet in bottom of filter housing.
5. Install filter in housing.
6. Install retaining bolt in filter housing.
7. Install filter up to bottom of electric lock off.
8. Tighten filter retaining bolt to 106 in-lb (12 Nm).
9. Open manual shut-off valve. Start vehicle and leak check
propane fuel system at each serviced fitting. Refer to
Propane Fuel System Leak Test.
Direct Electronic Pressure Regulator (DEPR)
Maintenance And Inspection
NOTE: Refer to Figure 3-93. GM 3.0 Dual Fuel System Components.
DEPR COMPONENTS ARE SPECIFICALLY DESIGNED AND CALIBRATED TO MEET
FUEL SYSTEM REQUIREMENTS OF THE EMISSION CERTIFIED ENGINE. IF THE
DEPR FAILS TO OPERATE OR DEVELOPS A LEAK, IT SHOULD BE REPAIRED OR
REPLACED WITH OEM RECOMMENDED REPLACEMENT PARTS.
1. Check for any fuel leaks at inlet and outlet fittings.
2. Check for any fuel leaks in DEPR body.
3. Check inlet and outlet fittings of coolant supply lines for
water leaks if applicable.
4. Check DEPR is securely mounted and mounting bolts are
tight.
5. Check DEPR for external damage.
6. Check DEPR electrical connections are seated and
locked.
