(7) Make a vertical mark on the inside and outside face of the frame rail 112 mm (4.5 in.) from the for- ward edge of the PLP hole in the sides of the rail. (Fig. 8)
(8) Using a straightedge, connect the two lines on
the top and bottom of the rail.
(9) Using the service tip as a guide, re-check your cut lines to ensure the service tip will fit when the cut is made.
CAUTION: Do not use any flame or plasma cutting equipment to cut the frame in this procedure. This is due to the inaccurate nature of the cut-line and the fact that the high temperatures achieved during flame or plasma cutting will change the metal char- acteristics and may weaken the frame and/or repair location.
(10) Using a reciprocating saw or equivalent, care- fully cut and remove the damaged frame rail tip. (Fig. 7)
DR FRAME (Continued)
CAUTION: Do not reuse damaged fasteners, quality of repair would be suspect. Failure to use only pro- duction fasteners or fasteners of equivalent hard- ness can result in loosening or failure. Do not drill any holes in the frame that are not specifically out- lined in this or other, DaimlerChrysler procedure as frame rail failure can result. When using heat to straighten frame components do not exceed 566°C (1050°F), metal fatigue can result.
NOTE: Procedures for 4X2 and 4X4 are common except as noted in this procedure.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the front wheelhouse splash shield. (Refer to 23 - BODY/EXTERIOR/FRONT WHEEL- HOUSE SPLASH SHIELD - REMOVAL)

DR FRAME (Continued) SERVICE SLEEVE ASSEMBLY
NOTE: Two sleeve halves are included with each kit. Modifications as follow, are necessary to create the correct sleeve assembly for each application.
(1) On 4X2 models, the 9lower9 sleeve is made by cutting off the tab and cutting out a notch in the bot- tom sleeve portion. Round the corners of the cut out to keep stress cracks from forming. On 4X4 models the 9lower9 sleeve is used as provided. (Fig. 16)
FRAMES & BUMPERS
13 - 11
(3) The sleeve halves are shipped slightly over- sized to allow custom fitting to each replacement frame rail tip. It is necessary to grind the mating surfaces to achieve the desired snug fit into the replacement tip (rail tube has increasing height rear- ward of the cut line). Once the two sleeve halves are fitted, bevel the edges 25° - 30°.
NOTE: Scribing a line 2 mm from the cut edge and then grinding back to the mark will simplify the bevel creation process and accuracy.
(4) Remove any burrs at the beveled edges. (5) Using the Weld Process Specifications table, weld the two halves of the repair sleeve together. (Fig. 18)

FRAME (Continued) STANDARD PROCEDURE - HYDROFORM FENDER RAIL REPAIRSAFETY PRECAUTIONS AND WARNINGS
WARNING: USE EYE PROTECTION WHEN GRIND- ING OR WELDING METAL, SERIOUS EYE INJURY CAN RESULT. † BEFORE PROCEEDING WITH FRAME REPAIR INVOLVING GRINDING OR WELDING, VERIFY THAT VEHICLE FUEL SYSTEM IS NOT LEAKING OR IN CONTACT WITH REPAIR AREA, PERSONAL INJURY CAN RESULT. † DO NOT ALLOW OPEN FLAME OR HEAT AND METAL SPATTER FROM ARC WELDING, TO CON- TACT PLASTIC BODY PANELS. FIRE OR EXPLO- SION CAN RESULT. † WHEN WELDED FRAME COMPONENTS ARE REPLACED, ENSURE COMPLETE PENETRATION WELD IS ACHIEVED DURING INSTALLATION. IF NOT, DANGEROUS OPERATING CONDITIONS CAN RESULT. † STAND CLEAR OF CABLES OR CHAINS ON PULLING EQUIPMENT DURING FRAME STRAIGHT- ENING OPERATIONS, PERSONAL INJURY CAN RESULT. † DO NOT VENTURE UNDER A HOISTED VEHI- CLE THAT IS NOT SUPPORTED ON SAFETY STANDS, PERSONAL INJURY CAN RESULT.
CAUTION: Do not reuse damaged fasteners, quality of repair would be suspect. Failure to use only pro- duction fasteners or fasteners of equivalent hard- ness can result in loosening or failure. Do not drill holes in top or bottom frame rail flanges, frame rail failure can result. When using heat to straighten frame components do not exceed 566°C (1050°F), metal fatigue can result.
CAUTION: This repair procedure assumes damage to the right or left hydroform fender rail (Fig. 19). Prior to any repairs, the vehicle must be mounted on the appropriate frame repair equipment (“frame rack”), checked with three dimensional measuring equipment, and necessary pull corrections made. If damage exists in the hydroform fender rail, or cab beyond the area covered by this service procedure after dimensional corrections are made, the hydro- form must be replaced in its entirety. Refer to 23 - BODY/BODY STRUCTURE/WELD LOCATIONS - SPECIFICATIONS, when replacing the entire hydro- form.

NOTE: Before the final welding, use three dimen- sional measuring equipment to ensure the part is in the correct location. Verify that tap plate extrusion at the bottom of the vertical post lines up with the isolator and hole in the frame perch mount. Also ensure the lower radiator closure tube is bolted into the forward shotgun ends.
(23) Complete welding by making a 360° butt weld
around the fender rails.

NOTE: Frame dimensions are listed in metric scale. All dimensions are from center to center of Princi- pal Locating Point (PLP), or from center to center of PLP and fastener location.
VEHICLE PREPARATION
Position the vehicle on a level work surface. Using screw or bottle jacks, adjust the vehicle PLP heights to the specified dimension above a level work surface. Vertical dimensions can be taken from the work sur- face to the locations indicated were applicable.

OPERATION
Fuel is returned through the fuel pump module and back into the fuel tank through the fuel filter/ fuel pressure regulator. A separate fuel return line from the engine to the tank is not used.
The fuel tank assembly consists of: the fuel tank, fuel pump module assembly, fuel pump module lock- nut/gasket, and fuel tank check valve (refer to Fuel Tank Check Valve for information).
A fuel filler/vent tube assembly using a pressure/ vacuum, 1/4 turn fuel filler cap is used. The fuel filler tube contains a flap door located below the fuel fill cap.
Also to be considered part of the fuel system is the evaporation control system. This is designed to reduce the emission of fuel vapors into the atmo-
sphere. The description and function of the Evapora- tive Control System is found in Emission Control Systems.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for extended service. They do not require normal sched- uled maintenance. Filters should only be replaced if a diagnostic procedure indicates to do so.
STANDARD PROCEDURE - FUEL SYSTEM PRESSURE RELEASE
Use following procedure if the fuel injector rail is, or is not equipped with a fuel pressure test port.
(1) Remove fuel fill cap.
DR FUEL DELIVERY - GAS (Continued)
(2) Remove fuel pump relay from Power Distribu- tion Center (PDC). For location of relay, refer to label on underside of PDC cover.
(3) Start and run engine until it stalls. (4) Attempt restarting engine until
it will no
longer run.
(5) Turn ignition key to OFF position.
CAUTION: Steps 1, 2, 3 and 4 must be performed to relieve high pressure fuel from within fuel rail. Do not attempt to use following steps to relieve this pressure as excessive fuel will be forced into a cyl- inder chamber.
(6) Unplug connector from any fuel injector. (7) Attach one end of a jumper wire with alligator clips (18 gauge or smaller) to either injector terminal. (8) Connect other end of jumper wire to positive
side of battery.

(9) Connect one end of a second jumper wire to
remaining injector terminal.
CAUTION: Powering an injector for more than a few seconds will permanently damage the injector.
(10) Momentarily touch other end of jumper wire to negative terminal of battery for no more than a few seconds.
(11) Place a rag or towel below fuel line quick-con-
nect fitting at fuel rail.
(12) Disconnect quick-connect fitting at fuel rail.
Refer to Quick-Connect Fittings.
(13) Return fuel pump relay to PDC. (14) One or more Diagnostic Trouble Codes (DTC’s) may have been stored in PCM memory due to fuel pump relay removal. The DRBt scan tool must be used to erase a DTC.
