❓ FAQ

Fuel enters at the outer surface of the element, passes the 10 micron media and leaves through a sealed centre tube, while water and debris fall into the bowl through gaps at the bottom. Clean fuel and settled contaminants do not share the same path, which reduces clogging.

R25T fits 245R series diesel engines, including the 2007 to 2009 Ram 6.7L Cummins applications that use this separator. Check that the housing takes a 1 inch-14 UNF centre thread and M14 x 1.5 ports before ordering.

R25T flows 45 gph (170 L/h) with a maximum operating pressure of 30 psi, and filters at 10 micron with 98% efficiency against water and solid contaminants.

The bowl has a self-venting drain port, so water and debris come out without removing the bowl. The clear nylon body lets you check the level and contamination before opening the drain.

Pre-fill the new filter with clean diesel fuel before mounting to avoid a dry start, lubricate the O-ring with a thin film of oil, then tighten the filter securely.

Description

Product Overview

This 10 micron fuel filter water separator assembly fits 245R series diesel engines, including the 2007 to 2009 Ram 6.7L Cummins applications that use this separator. It flows 45 gph (170 L/h) at up to 30 psi, stands 265 mm (10.44 in) tall, takes a 1 inch-14 UNF centre thread with M14 x 1.5 inlet and outlet, and replaces Fleetguard FS19778 and MANN-FILTER WK940/38X.

Key Features

Centre-tube flow path — dirty fuel enters at the outer surface, passes the 10 micron media and leaves through a sealed centre tube, so clean fuel and settled debris do not share a path.
98% water and solids rejection — water and particles are pushed out of the fuel before the injection pump, which is where a common-rail system is most exposed.
Sealed centre cylinder in the bowl — the collection bowl keeps filtered fuel separate from trapped water and debris, so what settles at the bottom is not drawn back up.
Self-venting drain port — water and debris drain without removing the bowl, and the clear nylon body lets you see the level first.
Powder-coated housing — the housing is coated after machining, so road salt and diesel spillage do not start corrosion on the outside.
