Diesel Engine Fuel Filter

The primary filter is typically installed on the suction side of the low pressure fuel pump with the secondary filter on the pressure side.

Diesel engine fuel filter. Todays diesel engines need to maintain high performance levels to remain compliant with stringent emissions regulations. The filter only has a single chance to capture contamination before the fuel moves on to the injectors and engine. Diesel fuel filters usually are made in the shape of a basin or bowl. Most diesels have two fuel filters.

This means the filter curves down. Water collects in the bottom of the bowl while an openclose valve at the bottom of the bowl allows the water to drain from the basin leaving only water. A typical passive diesel fuel filtration system installed on a hpcr injected engine uses both a primary filter and secondary filter to achieve the desired cleanliness level. Its important to remember the chemistry of an engine.

A better way to filter fuel. And a secondary filter up near the engine which gives the fuel a final cleaning before it gets to the fuel injectors. A primary filter located between the fuel tank and the engine which cleans the fuel before it gets to the fuel transfer pump. Fuel filtration plays a key role with current high pressure common rail fuel injectors operating at pressures up to.
