A basic service would include removing the filter element from the canister and back-flushing with solvent. Advanced filter services may additionally include Ultrasonic cleaning and post cleaning flow testing.
The required service interval will depend on filter volume and fuel contamination. We recommend a service interval of 12-months or 12,000 miles.
Yes, DW in-line filters are superior to typical OE fuel filters. Upgrading to a DW filter will usually result in decreased fuel flow restriction, increased service-interval, and longer fuel system component life.
To minimize cost and maximize flexibility, fittings are sold separately. DW offers fittings to adapt the filter port to a male 3/8 barb, male 5/16 barb, male -6AN, male -8AN, or male -10AN.
The filter canisters have female –8AN ORB ports. Larger, -10AN ORB endcaps are available upon request.
Diesel fuel systems have different filtration requirements than gasoline fuel systems. The DW in-line filters were designed specifically for gasoline fuel injection systems.
Yes, all DW in-line filters feature stainless and anodized aluminum internals and are e85 compatible.
Per the Bosch Automotive Handbook (9th edition 2014) “The required filter fineness is dependent on the fuel-injection system. For systems with manifold injection, the filter element has a mean pore size of approximately 10-microns. Finer filtering is required for gasoline-direct injection. The mean pore width here is in the range of 5-microns”. The vast majority of high performance fuel systems utilize manifold injection and therefore, a 10-micron filter element is appropriate.
Bosch recommends a filter element with a mean pore size of 10-microns for port manifold injection. Using a smaller mean pore size will introduce an unnecessary restriction in to the fuel delivery system.
If the in-tank pump is fitted with an adequate pre-filter (filter sock), then a single 10-micron filter installed before the fuel injectors is all that is needed.
