What You'll Learn

Reinstall the lines or hoses onto the fuel filter by hand
To reinstall the lines or hoses onto the fuel filter by hand, you will need to ensure that the arrow on the new filter is pointing toward the front of the vehicle. Secure the fuel filter to the fuel lines by holding the nut on the fuel filter with a flare nut wrench and turning the nut on the fuel line (clockwise) with another wrench. Repeat this step on both sides of the fuel filter. If your vehicle has quick-connect fittings, simply push the end of the fuel filter into the fitting until you hear a click.
For rubber hoses and clamps, push the rubber hose down onto the filter and secure it with the clamp. Repeat this on both sides of the fuel filter.
It is important to note that you should not use old hose clamps as the clamping force will not hold when tightened, causing a leak. Instead, place new hose clamps around the new fuel hose and install it onto the fuel line and fuel pump. If you have a fuel filter, snap the fuel line to the filter and ensure tight connections.
Finally, reinstall any clips and/or retainers as needed and reattach the inlet and outlet hoses to the new filter. Start the engine and check for leaks immediately.
