How to Hook Up the Fuel Pump on a 1994 Ford F450

A 1994 Ford F450 truck uses a high-pressure fuel pump thats part of an in-tank reservoir assembly, or ITR. The ITR also includes a shuttle selector valve, a supply check valve and a venture jet pump. Your fuel pump must be compatible with your trucks specific engine. The engine in a 1994 Ford F450 may be a 7.3L Diesel, 7.3L Turbo Diesel or 7.5L engine. All versions of the 1994 Ford F450 use electronic fuel injection.

Instructions

Drain the fuel tank and disconnect the cable to the batterys negative terminal with a socket wrench. Remove the fuel tank. Disconnect the fuel pump from the electrical connector, and clean the dirt from the area around the fuel pump. Disconnect the fuel lines from the fuel pump.

Place a wood dowel against the tabs of the fuel pumps locking ring and hammer the locking ring loose. Turn the locking ring counterclockwise to loosen it. Pull the fuel pump out and remove the gasket from the groove in the fuel tank.

Put the new fuel pump gasket into the matching groove of the fuel tank, and place the fuel pump into the fuel tank. Keep the fuel pump and gasket in place as you align the tabs on the locking ring with the matching slots in the fuel tank.

Turn the fuel pumps locking ring clockwise until it stops against the tab of the retainer ring. Ensure the gasket for the fuel pump is still in place.

Connect the fuel lines and the electrical connector to the fuel pump. Install the fuel tank and connect the cable to the batterys negative terminal. Fill the fuel tank.

How to Hook Up the Brake Controller on the 2006 Duramax

Duramax is the name of an 8-cylinder 6.6-liter diesel engine that General Motors has manufactured since 2001. The 2006 version carries the LLY designation and is an option for many full-size Chevrolet pickup trucks. The braking system on vehicles with a 2006 Duramax engine includes an electronic brake control module. The function of the EBCM is to keep the wheels from locking during an emergency stop by applying less braking force to a wheel that is rotating more slowly than the other wheels.

Instructions

Remove the negative battery cable with a socket wrench to prevent anyone from inadvertently starting the engine. Raise the vehicle with a floor jack and support it on jack stands. Clean the area around the EBCM under the vehicle with a shop cloth to prevent contamination of the disassembled braking components.

Disconnect the mounting screws for the EBCM with a socket wrench and discard the mounting screws. Pull the EBCM down slightly to detach it from the brake pressure modulator valve, or BPMV. Discard the EBCM.

Clean the mounting surfaces on the BPMV with a clean shop cloth to ensure a good electrical contact between the EBCM and BPMV. Install the new EBCM to the BPMV with new mounting screws and fasten the mounting screws with a socket wrench.

Lower the vehicle with the floor jack. Attach the negative battery cable with a socket wrench.

Turn the ignition on. Connect a scan tool to the data link connector under the dashboard on the left side of the steering column. Check and clear any error codes that the scan tool displays.
