Have Fuel Filter, Will Travel

By: Aaron Eisner

With today's high-performance car engines running on tight-tolerance fuel systems, having a top-of-the-line fuel filter in your Volvo sedan or pickup is a must. for most fuel-injection cars consist of a high-pressure canister, which is filled by a filtering agent. Fuel filters may have clamped, threaded or even special fittings that ensure a reliable fit to the fuel system. Fuel filters for carbureted engines have a lower tolerance for pressure than those for fuel-injected engines, as carbureted engines do not have to endure the same pressure-filled operating condition.

Unfiltered fuel is unforgiving, inducing rapid wear and tear in your Volvo engine. Contaminants include, but are not limited to, paint chips or dirt knocked inside the tank while filling up or the rust caused by the moisture inside the fuel tank. If these materials are not filtered, the fuel pump and injectors will give in to the abrading effects of the fuel contaminants on the high-precision parts of the fuel injection system. Fuel filters eliminate these contaminants, so more fuel can be burned efficiently. The more efficiently fuel is burnt, the performance of your Volvo improves dramatically.

Fuel filter designs (especially those found in diesel engines), consists of a bowl-like design which can collect water in the bottom of the bowl (as water is denser than fuel, so it sinks). As the water accumulates, it can then be removed via opening a drain and letting the water run out. Water can be an especially daunting opponent for engines, once it gets sucked into the fuel lines. The engine relies on the diesel to lubricate itself, but the water causes overheating and the unnecessary wear and tear of parts.

Fuel filters have a definite lifespan. While some can be taken out and cleaned (then reused again many times), most fuel filters have to replaced altogether. It can as simple as disconnecting the fuel filter from the fuel line and replacing it with a new one. If you don't replace your Volvo fuel filter regularly, it may become clogged with contaminants, which could restrict fuel flow. Restricting fuel flow could mean a drop in your Volvo's engine performance, as it fights to get enough fuel to function properly.

On carbureted cars, the filter needs to be replaced once a year. On fuel-injected cars, the standard is about 100000 miles before replacement. But the recommendation is every two years or about 24000 miles, whichever comes first.

You can find replacement almost everywhere. Most direct fit fuel filters have a 5/16 inch inlet and outlet that connects to your Volvo's fuel line. Measuring 6 17/32 inches, it contains a mounting bracket stud. The stud is threaded, so it screws easily in place. Some also contain an anti-drainback valve.

Today's Volvo car engines have stringent fuel requirements so it could function effectively and efficiently. Meeting those specifications entail having a demanding fuel filter in your system.

Have fuel filter, will travel.
