Fuel from the tank gets to the engine through the fuel line, which is basically a pipe. Fuel travels all the way to the fuel pump and to the fuel delivery system to supply the needed amount of fuel for combustion and power generation. The line is braided within with various strands of material. But though this pipe is reinforced for better strength, it may split when fuel sits on the line for a long time. Slimy deposits can accumulate and clog the line. The pipe may also get rusty or corroded or even split, causing leaks. This can mess up fuel delivery to the engine, resulting in poor engine performance and even in riskier outcomes like fire. Good thing, we have some how tos for fixing leaky or damaged fuel lines.
Note: When working on fuel lines, you have to wear the right gear: safety goggles and work gloves. It's also better if you wear a long-sleeved shirt. The work area should be properly ventilated to avoid accidents.
How to clean clogged fuel lines
Step 1: Inspect the gas cap. Use a soft cloth to get rid of any stuck dirt or debris in the lid.
Step 2: Disconnect the fuel line from the carburetor. You either have to unscrew it or pull out the clamp.
Step 3: Drain the gas tank using a siphon pump. Collect the drained fuel through the pump into an approved container. You have to check manufacturer instructions on how to use the siphon pump and what container to use when draining the tank.
Step 4: Take out the carburetor before removing dirt or slime. Disconnect the carburetor by unscrewing it. Undo screws that link the carburetor body to the float bowl. After you carefully pull out the float bowl, use a carburetor cleaner to remove slime and dirt that has settled in the bowl.
Step 5: Wash out the fuel line using new fuel. The new fuel should be able to break down slime that has built up. Under the line, there should be a drip pan to avoid making a mess and causing accidents.
Step 6: Hook up a nozzle (with the tapered end) to a running compressor. After cleaning the line, you have to dry this out. Blowing air through the line will help. Make sure that the inside of the gas tank is free from debris, which may be blown through the line.
Step 7: Reconnect the fuel system pipe to the carburetor. Put back all the connections you've removed.
Step 8: Refill the tank with new fuel.
How to install new fuel lines
Step 1: Pull off the fuel line from the gas tank. Use a flat-blade screwdriver to loosen the clamp's screw. This clamp secures the line that slides onto a metal nipple. As you disconnect the line, make sure that its end is wrapped with a plastic bag to hold fuel that'll come out of it. Don't worry.the detached line won't release the entire fuel in the tank.
Step 2: Detach the line from the brackets that run along the fuel tank to the engine. Unfasten the brackets by removing the screw or bolt using a flat-blade screwdriver or a wrench. After opening the bracket, you can pull out the line.
Step 3: Disconnect the fuel lines from the fuel pump. For this, you have to disengage the clamps using a flat-blade screwdriver. As you disconnect the lines, wrap their ends with plastic bags. Do the same as you pull out the line connected to the fuel delivery system.
Step 4: Cut off the new fuel line to the same length as the old ones. You may use a utility knife for this.
Step 5: Use the hose clamps you've detached from the old lines to the ends of the new fuel lines.
Step 6: Attach the shorter line to the pump and fuel delivery system. Seal the connection with clamps.
Step 7: Move the longer line beneath the vehicle. The other end should go to the fuel pump. After sliding the hose onto the fuel pump fitting, you have to secure this with the clamp.
Step 8: Place the line into each ends of the metal brackets. Secure these brackets to the frame with their fasteners. You may use a flat-blade screwdriver or wrench for this.
Step 9: Guide the other end of the fuel line to the gas tank. Seal this with the hose clamp.
