One of the main inquiries we receive have to do with power loss, hesitation and hard starting in a vehicle. You would be surprised to know how many of these complaints can be traced to a clogged fuel filter. The more miles you put on your vehicle, the more contaminants your fuel filter traps, gradually restricting the amount of fuel being delivered to your motor. A poor flowing fuel filter can pass enough fuel to maintain the engine at low speed or cruising conditions, but may starve the engine at higher speeds or highway speeds. Replacing the fuel filter in your vehicle once a year as preventative maintenance is a good idea that reduces the risk of the fuel filter clogging up and further damaging the large investment that is your motor and vehicle. Brand new cars right from the dealer are as susceptible to getting dirty fuel as any other car so even though the car is new, the fuel filter will start to clog fairly quickly.
If you own a carbureted vehicle, the fuel filter is usually found at the inlet fitting, of the carburetor or a inline fuel filter is used between the fuel pump and the carburetor itself. When you go to replace the filter, take care to not strip or otherwise damage the fittings or pipe thread. The threads in the carburetor are relatively soft and can be damaged easily, so make sure to snug the fittings only, tight enough so there wont be a leak, but loose enough to not damage the housing or the fitting itself. To seal the fitting and lines, use Teflon tape to create a proper seal where the fittings will be interacting with the fuel being delivered to your motor. Take note of fuel filter orientation although most fuel filters have some sort of indicator showing which way the fuel flow goes, not all filters do, so please make note of your vehicles flow orientation before replacing your fuel filter.
If you own a fuel injected vehicle, fuel filters are usually encased in a metal housing and contain a filter element that protects fuel injectors more efficiently than fuel filters on carbureted engines. Fuel injected vehicles use a hardline to maintain, deliver and pressurize the fuel system before starting. These types of engines also maintain a high level of fuel pressure, even if the car has not been run recently. Follow the manufacturers procedure on how to depressurize and service your fuel system.
