After filtration, the lighter diesel fuel flows to the interior of the filter towards the outlet.Consists of several layers of cloth wound over a layer of link cloth on a perforated metal tube, Filtered fuel collects in the centre tube and is delivered to the pump, Special filter media achieves high storage capacity and separation of fine particles.
