The fuel system is a critical part of your car as this part keeps your vehicle moving. It needs to be taken care of and checked once in a while. Rust and gummy build-ups on your fuel lines may cause blockage and problems in your car’s system.
If you feel like there must be a problem with your fuel lines, or you find any leaks, do not hesitate to get it fixed by a mechanic. However, you can do the work successfully on your own by following this guide on how to clean fuel lines on a car.
Step 1: Elevate your car and disconnect the battery terminals
After preparing the materials and tools, drive your car and position the back wheels on the car ramps for elevation. This step is optional but recommended so that you can work easily below your car.
Before you start on your fuel lines cleaning work, put on your working gloves.
Also, make sure that no fire starter is around. Put a no smoking sign if possible, and keep your fire extinguisher near.
Then, open the car’s front cover to expose the engine and make sure that the negative battery terminal is disconnected from your battery. You might cause problems like fire and sparks when cleaning the fuel line without removing it.
Step 2: Locate your fuel lines and disconnect them from other parts of the fuel system.
Most cars have different builds of their fuel system. Find your car’s user manual to locate the fuel lines, and identify your car’s fuel system.
You can clean your fuel lines without the removal of your fuel tank.
1. Loosen the clamp that is on the end of your filling hose, and wiggle the hose until it disconnects from the tank.
2. Locate the top opening of your fuel tank which is usually located below your car’s back seat.
3. Open the cover by undoing the screws using a screwdriver. Once removed, you can see the fuel line/s attached to the fuel pump.
4. When you clean the fuel system in a car, you only put cleaners in the high-pressure fuel lines where the fuel flows.
For a single fuel pipe system, detach the only high-pressure fuel line from your fuel pump by popping and/or pressing the safety tabs.
For a twin fuel pipe system, locate two high-pressure fuel lines attached to your fuel tank and detach them by undoing the safety tabs or screws.
5. Lastly, go to the front of your car and disconnect the high-pressure fuel line/s from your carburetor or fuel rail, whichever is applicable.
Step 3: Flush the high-pressure fuel lines with cleaner
There are available fuel system cleaners in the market that are used to clean the fuel system in a car.
However, you must use a gas line cleaner like Lucas Upper Cylinder Lubricant & Fuel Injector Cleaner, which is used to clean fuel injectors and can clean gummed-up fuel lines due to its chemical composition.
Place a catch basin on your fuel tank. Then, elevate the high-pressure fuel lines into the catch basin.
On the other end of the fuel lines, inject or pour your cleaner and insert the air nozzle to use the compressed air to clean the fuel lines. You should see dirt or any debris in the basin.
Use rubbing alcohol if a gas line cleaner is not available, as the composition of this alcohol will help clear a clogged fuel line.
Repeat this step as needed.
Step 4: Clean the fuel filler hose
Cleaning the filler hose is critical for fuel system cleaning because if this part is not cleaned thoroughly, dirty fuel will go inside your fuel tank.
Spray water into the filler hose, using the garden hose that is attached to a water source. Do this until you only see clear water coming out.
To force the water out and clean other debris or rust, pour rubbing alcohol using a funnel until the liquid that is coming out is clear.
Step 5: Put the disconnected lines back into the fuel system.
Attach back the fuel filler line into the fuel tank, and then tighten the clamps. Connect the high-pressure fuel lines back to the fuel tank or fuel pump, and also on the other end to the carburetor or the fuel rail.
When putting back all the lines, make sure that the safety tabs are secured and locked so that there will be no leaks.
Do not forget to attach back the negative battery terminal to the battery.
