Fuel Filler Hose
With gas prices going up every year, it's important that you make every drop of fuel count. However, this becomes a difficult task once your car is showing signs of a possible fuel filler hose leak. If gas leaks whenever you fill up the tank, then the filler hose might be damaged. A lot of things can cause a gas leak, so make sure you rule out other possible culprits. Once you've determined that a cracked or loose filler hose is the source of the leak, you'll have to repair or replace it to prevent further leaks. To help you deal with a hose leak, check out the tips below.
Never use a tape to cover up holes or cracks.
Now you might think of taping up the fuel filler hose, but this isn't a good idea. As a matter of fact, it's a very bad idea so you should definitely ditch it. Remember, whatever tape you use, it will eventually disintegrate because gasoline and adhesives don't mix. The worst thing that could happen is for a piece of tape to get dislodged and stuck inside the filler hose, clogging up the fuel system in the process.
Use a silicone sealer to temporary plug holes.
If you really can't replace the busted fuel filler hose as soon as possible, or you're still saving money for the replacement, a better idea than tape is to use a silicone sealant. However, make sure the product label says that it's a neoprene type of sealant. Keep in mind that if it's not neoprene, it will eventually disintegrate and just clog up the hose; even the toughest silicone sealers will eventually break down after regular exposure to gasoline. Also, this solution is only temporary and is only applicable to very small holes or cracks. Aside from a silicone sealant, you might also want to try plugging up the cracks or holes with some fuel tank sealer that's usually applied on aircraft fuel tanks.
Replace a leaking fuel filler hose as soon as possible.
If you have the time and money to purchase a replacement hose, the better it is for your car's fuel system. This is because plugging holes or cracks is a temporary solution. Sooner or later, the sealant you've applied will lose its sealing capabilities because of fuel exposure. If you're worried about your lack of repair skills or car repair experience, don't be. Replacing a fuel filler hose is an easy task as long as you're equipped with the right tools.
Depending on your car make and model, you might need to remove the fuel tank in order to access and replace the filler hose. Always consult your vehicle manual if you don't know which parts to remove first in order to remove an old hose and install a new one. Once you've figured this part out, the rest of the installation process is pretty straightforward. To prevent accidents when replacing a busted hose, make sure everyone in your house knows you're tinkering with the fuel tank. This means no smoking near the garage and electric cables within the working area should be removed.
