4. Protective Equipment: Wear chemical-resistant gloves and safety glasses. Fuel can irritate skin and eyes.

3. Installation Procedure

A. Removal of Old Components

Fuel Lines:

1. For Quick-Connect Fittings: Release the locking mechanism according to manufacturer instructions (push-button, pull-tab, or special tool required). Be prepared for residual fuel drainage.
2. For Clamp-Type Hoses: Loosen clamps and twist the hose to break the seal before pulling. Never use excessive force.
3. Plug Openings: Immediately cap or plug all open fuel lines and ports to prevent debris entry and minimize fuel spillage.

Fuel Pump (In-Tank or External):

1. Note the orientation and routing of all electrical connections and fuel lines before removal. Take photos for reference.
2. Carefully extract the pump assembly, avoiding damage to the fuel level sender arm.
3. Inspect and replace the fuel pump gasket/seal and filter (if applicable).

Carburetor/Fuel Injector:

1. Remove the air cleaner assembly to access the component.
2. Disconnect throttle cables, choke cables (for carburetor), and electrical connectors (for injectors).
3. Cap the intake manifold openings immediately to prevent debris from entering the engine.

B. Installation of New Components

General Rules (For ALL Fuel Components):

WARNING: Use only approved fuel-resistant components. Standard rubber vacuum hose will deteriorate rapidly when exposed to modern ethanol-blended fuels, leading to leaks and fire.

Fuel Lines Installation:

1. Cut Cleanly: Cut fuel hose squarely using a sharp knife or hose cutter. Do not use scissors or dull tools that can deform the hose.
2. Insert Fully: Push the hose onto the barbed fitting until it seats against the hose end. For push-to-connect fittings, push until you hear an audible "click" and the locking tabs engage.
3. Verify Connection: Gently pull on the connection to confirm it is securely locked.
4. Clamp Properly: Position clamps 3-5 mm from the hose end. Use only fuel-injected grade clamps (constant tension or EFI-specific worm gear clamps).

Fuel Pump Installation:

1. Clean Sealing Surfaces: Ensure the tank mounting surface is clean and free of old gasket material.
2. New Gasket/O-Ring: Always install the new gasket or O-ring provided with the kit. Lubricate the O-ring with clean engine oil or assembly lubricant to prevent rolling during installation.
3. Torque: Tighten mounting fasteners evenly in a cross pattern to manufacturer specification (typically 8-12 N·m for pump covers). Overtightening can distort the flange and cause leaks.
4. Electrical Connections: Ensure connectors click securely into place. Verify wiring is routed away from sharp edges.

Carburetor/Fuel Injector Installation:

1. New Gaskets/O-Rings: Always use new intake manifold gaskets or injector O-rings. Lubricate O-rings lightly with clean engine oil or assembly lubricant.
2. Fuel Injector Seating: Push the injector into the fuel rail and intake manifold until fully seated. The retaining clip should lock into position with an audible click.
3. Carburetor Installation: Ensure the carburetor seats squarely in the intake boots. Tighten clamp bolts evenly but do not overtighten—just enough to prevent air leaks and secure the carburetor.

Fuel Tank Installation (If Removed):

1. Isolators/Pads: Apply soapy water or rubber lubricant to tank isolators to ease installation. Ensure the tank is fully seated on the isolators.
2. Line Routing: Verify all lines (fuel supply, return, vent) are routed away from exhaust, sharp edges, and moving parts. Ensure no wires or hoses are pinched under the tank.
3. Fasteners: Torque tank mounting bolts to specification (typically 20-25 N·m for rear tank bolts).

4. Operation: Functional Checks

Pre-Start Checks

WARNING: Perform all leak checks in a well-ventilated area away from ignition sources. Have a fire extinguisher nearby. Do not operate the engine if any leak is detected.

1. Visual Inspection: Verify all connections are secure, all clamps are tightened, and all electrical connectors are locked.
2. Fuel System Priming (Fuel-Injected Models):
   • Turn ignition ON (do not start engine).
   • The fuel pump should run for approximately 2 seconds to pressurize the system.
