Making sure only clean fuel reaches critical fuel system components like carburetors and injectors is important on any vehicle, but especially so on cars with powerful performance and racing engines. The average driver probably won't notice a slight drop off in performance caused by dirt clogging a carburetor passage or disrupting an injector spray pattern. But when every horsepower and tenth of a second at the track counts, you can't afford to let dirt rob power and slow you down.
But while filtration is crucial, it can't be obtained at the expense of the fuel volume needed to feed big carburetors or injectors. Our performance fuel filters are constructed to deliver clean fuel without sacrificing fuel flow, so you don't have to worry about engine damage or fuel starvation. And they're designed to fit into the structure of performance fuel systems and meet the requirements of specific fuels. No matter how you have your fuel system configured or the type of fuel you're using, we have the filters.
Performance fuel filters are commonly rated in microns - the smaller the micron number the finer the filtration - and some are also rated for flow, usually in Gallons Per Hour (GPH). Many performance fuel systems are configured for an external fuel pump, in which case a higher micron number filter, 100 for example, would be used between the tank and pump to protect the pump. A finer 40 or 10 micron filter would be installed after the pump to protect the carburetor or injectors respectively. We offer both in-line filters, with and without replaceable filter elements, and canister filters. These filters come in a wide range of sizes and with adapters can be connected to most common AN fitting and line sizes.
Most aluminum in-line filter housings have an attractive corrosion-resistant anodized finish that's often available in a selection of colors, for a neat professional look that will perfectly complement your vehicle. Many 100 micron filters use a woven stainless steel mesh filtering element that can be cleaned, while 10 micron filter elements are commonly fiberglass or cellulose and must be periodically replaced. Some in-line filters come with a built-in fuel shutoff valve to minimize fuel loss during filter cleaning or changes. Canister filters come with replaceable cartridge or spin-on filter elements, and some elements have a petcock at the base of the filter so water can be drained.
Diesel fuel systems have their own special needs. Diesel fuel absorbs water easily and in addition to contaminants, diesel fuel pumped from the fuel tank also contains power-robbing air and vapor. Besides the previously mentioned fuel filters that allow water to be drained, we also offer complete fuel filter/lift pump units. In these systems fuel from the tank enters a filter/water separator where dirt and water are removed before entering the pump. Pressurized fuel from the pump then enters another filter where any remaining dirt is strained and air/vapor is separated from the fuel. Only pure fuel is sent to the injection pump/injectors ensuring long component life and full pressure for maximum power output.
