R2.8 CM2220 R101B Fuel System Section 1 - Installation by Subsystem Page 1-15 2 Fuel supply from fuel tank (filter inlet), 9.5 mm male Society of Automotive Engineers (SAE) J2044 quick disconnect fitting (an adaption fitting for the 9.5 mm male SAE J2044 quick disconnect to a 3/8 inch hose barb is provided in the Filter Kit, PN 5299831) 3 Slots, two places – 17 x 11 mm [0.7 x 0.4 in], 46.5 mm [1.83 in] center-to-center 4 Fuel supply to fuel pump (filter outlet), 9.5 mm male SAE J2044 quick connect fitting (an adaption fitting for the 9.5 mm male SAE J2044 quick disconnect to a 3/8 inch hose barb is provided in the Filter Kit, Part Number 5299831) 5 Water drain valve 6 WIF sensor 7 Fuel pump 8 Required distance for filter removal 12 mm [0.5 in], filter height 205 mm [8.1 in].
NOTE: The fuel hose to the filter from the fuel tank and the fuel hose from the filter to the fuel pump are supplied by the customer. The R2.8 CM2220 R101B engine kit provides a fuel filter with provision for vertical chassis mounting. The filter assembly contains a WIF sensor and water drain valve. The WIF will detect the presence of water in the fuel. The filter assembly also contains an integrated fuel priming pump. Drain the water fuel separator into a container and dispose of in accordance with local environmental regulations. WARNING Do not pre-fill the pressure-side fuel filter with fuel. The system must be primed after the fuel filter is installed.
Pre-filling the pressure-side fuel filter can result in debris entering the fuel system and damaging fuel system components. CAUTION The filter assembly should not be mounted in very dirty areas such as wheel wells, to reduce the potential for contamination of the system during filter change. Adequate clearance for scheduled maintenance and proximity to sources of heat must also be considered when selecting the mounting location of the filter assembly. The optimum vertical location for the fuel filter is between the top of the fuel tank and the top of the engine valve cover. See Figure 1 and Figure 3 for mounting dimensions for the filter head assembly.
Mechanical over-tightening can distort the threads as well as damage the filter element seal or filter can. NOTE: Do not pre-fill the fuel filter. CAUTION Install the fuel filter on the filter head. Tighten the filter until the gasket contacts the filter head surface. Tighten the fuel filter an additional 3/4 of a turn after contact.
