96 Chevy Tahoe fuel line ????'s

[BBsound]

Well I fired up my Tahoe Sunday and smelled gasoline, found fuel spraying out from the rear wheel well!:Wow1:

:Mechanic:We have a trip to go on wednesday, and I am wondering if anybody has any info on replacing the lines from the top of the tank to the frame rail.

I did not have time to work on it Sunday, but I am going to drop the tank today after work.

Removal Procedure

1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure . See: Service and Repair
3. Disconnect the fittings at the engine compartment fuel feed and return pipes.
4. Disconnect the fuel pipe attaching hardware.
5. Disconnect the fuel feed and return pipe nuts at the fuel inlet and fuel outlet assembly.
6. Disconnect the fuel feed and return pipes and O-rings. Discard O-rings.
7. Remove the fuel tank. Refer to Fuel Tank Assembly . See: Fuel Tank\Service and Repair
8. Disconnect the fuel feed and vapor hoses. The quick-connect fittings at the fuel sender assembly. Refer to Fuel Line Coupler . See: Fuel Line Coupler\Service and Repair
9. Remove the hardware retaining section of pipe to be replaced. Note location of attaching hardware for installation.
10. Remove the section of pipe and hoses.
11. Remove rust or burrs from the engine compartment fuel pipes by the following procedure:

11.1. Use emery cloth in a radial motion with the fuel pipe end in order to prevent damage to the O-ring sealing surface.
11.2. Using a clean shop towel, wipe off the male tube ends.
11.3. Inspect all the Connectors for dirt and burrs. Clean or replace the components/assemblies as required.

Installation Procedure

WARNING: To Reduce the Risk of Fire and Personal Injury: Before connecting the fitting, always apply a few drops of clean engine oil to the male pipe end. This will ensure proper reconnection and prevent a possible fuel leak (During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated .

1. Install the new O-rings on the engine fuel feed and return pipes.
2. Connect the fuel feed and return pipes to the fuel injection unit. Finger tighten only.
3. Connect the fuel pipe attaching hardware. Tighten

o Fuel pipe attaching nuts to 27 Nm (20 lb. ft.) using a back-up wrench.

4. Position new fuel pipe harness in original location and fuel pipe harness attaching hardware.
5. Remove protective caps from one end of both fuel pipes. Leave caps on other end of pipes to prevent dirt from entering.
6. Apply a few drops of clean engine oil to the male connector tube ends.
7. Connect the quick-connect fittings at the fuel feed and pipe near the in-line filter and at the fuel sender assembly. Refer to Fuel Hose and Pipes . See: Fuel Pressure Connection
8. Install the fuel tank and attaching hardware if the tank was removed.
9. Tighten the fuel filler cap.
10. Connect the negative battery cable.
11. Check for fuel leaks.

11.1. Turn the ignition switch to the ON position for 2 seconds.
11.2. Turn the ignition switch to the OFF position for 10 seconds.
11.3. Again, turn the ignition switch to the ON position.
11.4. Check for fuel leaks.

FUEL PRESSURE RELIEF PROCEDURE

TOOLS REQUIRED

* J 34730 Fuel Pressure Gauge

WARNING: Relieve the fuel system pressure before servicing fuel system components In order to reduce the risk of fire and personal Injury. After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the chance of personal Injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may leak out. Place the towel In an approved container when the disconnection Is complete .

1. Disconnect the negative battery cable in order to avoid possible fuel discharge if an accidental attempt is made to start the engine.
2. Loosen the fuel filler cap in order to relieve the tank vapor pressure.
3. Connect the gauge J 34730-1A or the equivalent to the fuel pressure connection.
4. Wrap a shop towel around the fitting while connecting the gauge in order to avoid spillage.
5. Install the bleed hose into an approved container and open valve in order to bleed the system pressure. The fuel connections are now safe for servicing.
6. Drain any fuel remaining in gauge into an approved container.

FUEL PRESSURE CONNECTION

REMOVAL PROCEDURE
The fuel pressure connection is non-replaceable, but it is serviceable.

1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure . See: Service and Repair
3. Remove the fuel pressure connection cap.
4. Using a standard valve core removal tool, remove the valve core assembly.
5. Discard the valve core assembly.

INSTALLATION PROCEDURE

1. Using the standard valve core tool, install a new valve core assembly.
2. Connect the negative battery cable.
3. Inspect for fuel leaks through the following steps:

3.1. Turn ON ignition switch for 2 seconds.
3.2. Then turn the ignition switch to the OFF position for 10 seconds.
3.3. Again turn the ignition switch to the ON position.
3.4. Check for fuel leaks.

4. Install the fuel pressure connection cap.

IF you want pics i can email you.
