We stock a broad range of diesel fuel filter assemblies, agglomerators (water traps), and sedimenter units (traps fuel sediment). A fuel filter is a vital component in an internal combustion engine. Fuel in a fuel tank can contain a number of unwanted contaminants. This can include dirt that has found its way into the fuel tank during filling or rust that has accumulated in a steel fuel tank because of moisture. If these contaminants were to remain in the unfiltered diesel fuel, abrasion caused by these particles in the precision-engineered parts of a diesel engine, could cause significant wear and possible failure of a fuel pump and injectors. More efficient burning occurs if contaminants are removed from fuel too, improving engine performance.

Some filter assemblies on diesel engines have a bowl like design. The bowl could be either a sedimenter which allows contaminant particles to settle at the bottom of the bowl which can be removed, or an agglomerator which allows water to collect at the bottom which can be drained off.

The filter assemblies we stock at Darwen Diesels predominantly pre-date the common rail diesel engine, but we do offer a limited number that are appropriate for common rail engines. The filter assemblies are for agricultural, marine and plant diesel engines as well as cars and commercial vehicles.

We have in excess of 120 filter assemblies in stock. These include:

Toyota, Nissan, and Ford Transit filter assemblies with Bosch, ½” UNF (Imperial), 14mm, 12mm (Metric) assembly with primer, (short/long glass) agglomerator. They are also available from us without primers and single/double with long or short glass or aluminium base. As we stock the majority of necessary parts, we can make uppractically any filter assembly to your specifications.

We also have filter assemblies with sedimenter units: ½” UNF (Imperial)12mm, 14mm (Metric) with single or double base, and with water trap, both ½” and 14mm (with flow Left to Right, Right to Left). They are also available with electric pumps, Marine Sedimenters, and Marine UNF single, both with/without a glass base, (and both long and short), and 14mm special marine and repairable filter assemblies.
