2001 Ford F-150 Draining-Coalescer/ Pressure Relief-Natural Gas Bi-Fuel System Repair Manual

1. Relieve the Bi-fuel system fuel pressure. For additional information, refer to Pressure Relief—Natural Gas Bi-Fuel System. 2. Raise the vehicle on the hoist. For additional information, refer to Section 100-02. 3. NOTE: There is an O-ring attached to the drain plug. The O-ring must be replaced each time the drain plug is removed. Remove the drain plug. 4. Install the drain plug. 5. Lower the vehicle. 6. Pressurize the fuel system. WARNING: It is important that your bi-fuel vehicle be correctly maintained by Ford bi-fuel trained personnel. If a concern occurs, it is important that correctly trained personnel diagnose the cause. If a concern relates to the fuel system, correct part replacement is imperative to keep your vehicle operating at normal performance. Bi-fuel components and gasoline specific components are not interchangeable. If your vehicle is not serviced in accordance with bi-fuel service procedures, damage can occur and your warranty may be invalidated. WARNING: Fuel supply lines are always pressurized. When servicing fuel related components, do not smoke or carry lighted tobacco or an open flame of any type. Flammable mixtures may be present and can ignite, resulting in personal injury. WARNING: The natural gas fuel system is always pressurized to 655 kPa (95 psi) downstream of the fuel pressure regulator and up to 24821 kPa (3,600 psi) upstream of the fuel pressure regulator. Use care when servicing the fuel system or personal injury can occur. WARNING: The natural gas fuel supply manifold is pressurized to 655 kPa (95 psi). Fuel pressure must be relieved prior to any fuel system service. WARNING: The fuel system pressure must be relieved before any component can be removed. The fuel tanks must be evacuated prior to tank removal. Removal of components without pressure relief or tank evacuation can cause natural gas to escape into the air and cause injury or death.

Ford V8 Engines Performer RPM Hydraulic Roller Camshaft INSTALLATION INSTRUCTIONS

Disconnect the battery. 2. Drain radiator coolant. Drain plug will normally be located on lower right or left side of the radiator facing the engine. 3. Remove radiator and air conditioning condenser if so equipped. In some cases, the front grill may have to be removed. Measure distance from front cover to grill or brackets that may interfere with camshaft against the length of the camshaft. 4. Remove the gas cap to relieve pressure. Disconnect fuel line and plug. Replace gas cap. 5. Disconnect all linkage from carburetor such as throttle, throttle springs, transmission, cruise control and automatic choke. 6. Tag and remove coil wires and sensor wires. 7. Tag and remove vacuum lines. 8. Remove valve covers. 9. Remove distributor cap and wires, rotate engine until rotor points towards number 1 terminal in cap and pointer on front cover is on top dead center (TDC) and remove distributor. (see Fig. 1) Note: Mark the approximate position of the distributor housing in relation to the manifold to assist in getting the distributor properly located during re-installation. 10. Remove carburetor and intake manifold. Remove and discard intake manifold gasket. 11. Remove rocker arms and pushrods. CAUTION: If your engine has non-adjustable rocker arms (1969-1/2 or later), you must install screw-in studs and high performance •VALVE SPRINGS CAUTION: WARNINGS ABOUT YOUR WARRANTY In order for this Performer RPM roller cam to be covered under ANY WARRANTY, you MUST use the correct Valve Springs. Failure to install the correct valve springs may cause lifters not to follow the cam lobes and damage engine parts. This camshaft is designed to function with valve springs that have a closed pressure of 110 lbs, open pressure of 320 lbs and a lift of .575″. Special H.P. retainers may be necessary with your installation for proper spring height. Do not use rotator type valve springs or retainers for this application. Note: Edelbrock Sure Seat Valve Springs #5762 are not recommended.  IMPORTANT NOTES AFFECTING YOUR WARRANTY CAM LOBE DAMAGE – Cam lobe wear is almost non-existent unless mismatched parts are used or installation of the cam and lifters is done improperly. Cam damage can result from the timing gear loosening due to improper torque on bolts. Bolts holding gear to camshaft should be torqued carefully and a locking compound applied to threads of bolts. Before installing your new Performer-RPM roller camshaft, check the gear drive on the distributor and oil pump for any signs of wear. If worn, be sure to replace with a new gear or you may wear out your camshaft prematurely. High-pressure oil pumps are not recommended with Performer RPM roller camshafts. Edelbrock camshafts are designed to use with Edelbrock timing chains.  CAM GEARS AND CAMSHAFT END PLAY- If cam gear becomes loose, the cam will slide back in the block, causing the lifters to hit the lobes next to them and also the cam bearing journals. If the engine is run after this happens, the bottom of the lifters and the sides of the lobes will become damaged. See Installation Instructions section for end play specifications.  LIFTERS Edelbrock offers a retrofit roller lifter kit for engines not originally equipped with roller lifters. Use part #97453. To install your roller lifters, use fresh clean oil on the lifter and the lifter bore just prior to installing. The guide bar (high side of tappet) must face the opposite side of block. See roller lifter instructions for additional information. ( Note: 289-302 engines require removal of the cylinder heads to provide enough clearance to install roller lifters, which are taller than standard hydraulic lifters.)  PUSHRODS AND ROCKER ARMS High performance pushrods, roller rocker arms and rocker studs are recommended for this installation. After the cam is installed and timed correctly (see Figure 2), it will be necessary to check each pushrod for correct lifter preload. INSTALLATION INSTRUCTIONS 1. Check lifters as covered in Lifters section. Coat cam lobes with fresh clean oil. Lube distributor drive of cam with assembly lube (supplied). 2. Install new camshaft. Re-install thrust plate with new sprockets and timing chain with timing marks lined up as recommended by factory specifications (See Figure 2). Reinstall the fuel pump eccentric before installing sprocket bolt and washer
