EVAP filter. EVAP canister. EVAP vent control valve. EVAP pressure sensor. IMPORTANT: Before any parts are removed from the vehicle, note the EVAP filter orientation and hose routing (take a photo). Hose routing and EVAP filter orientation is critical and varies depending on production date. IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it contains information that is essential to successfully completing this repair. Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle. 1/6 SERVICE PROCEDURE 1. Replace the Fuel filler tube, EVAP filter, EVAP canister, EVAP canister vent control valve, and EVAP control system pressure sensor. 2. Inspect the EPT seal material on the service fuel filler tube. EPT material has NO contact If the EPT seal material on the NEW fuel filler tube is loose or has any area of no contact, continue to step 3, below. If the EPT material is properly secured to the NEW fuel filler tube, continue to step 4 on page 4. Figure 1 3. Wrap EPT foam (see PARTS INFORMATION on page 6) around the top of the new fuel filler tube where indicated in Figure 2. Filler tube drain box IMPORTANT: The EPT foam must completely seal the filler tube drain when applied. Read steps 3a–f before proceeding. Drain hose fitting This area will be sealed Figure 2 a. Peel the self-adhesive protective sheet back several inches from the end of the EPT foam strip. NOTE: The EPT foam is the same on both ends. b. Insert the EPT foam strip so it seals tightly against the drain hose fitting. EPT foam strip sealed against drain hose fitting Drain hose fitting Figure 3 2/6 NTB19-037 c. Wrap the top of the EPT foam strip tightly around the drain hose fitting. d. Peel the self-adhesive protective sheet and then wrap the EPT foam 360 degrees around the filler tube drain box. Wrap the EPT foam strip around the drain hose fitting Wrap the EPT foam so that its width extends above and below the fuel filler tube drain box. Figure 4 Top of fuel filler tube NOTE: The EPT foam should fit tightly around the top of the fuel filler tube and the fuel filler tube drain box; slack at the bottom will be removed in the next step. EPT foam strip sealed against drain hose fitting End the wrap with the EPT foam tightly sealed against the drain hose fitting. Figure 5 e. Start here. Work evenly around to the opposite side. Press the EPT foam adhesive to the fuel filler tube evenly, pushing the slack around to the opposite side. Figure 6 3/6 NTB19-037 f. Close the excessive EPT foam by pinching the excess together as shown in Figure 7, and then press the remaining EPT adhesive to the fuel filler tube. IMPORTANT: The EPT foam must be completely sealed at the top, bottom, and to the drain fitting. Confirm that no openings are present. Pinch EPT foam together Figure 7 4. Install the new EVAP canister vent control valve and new EVAP control system pressure sensor onto the new EVAP canister. NOTE: For steps 4 through 7, refer to the Electronic Service Manual (ESM) section ENGINE > FUEL SYSTEM > VK56VD > REMOVAL AND INSTALLATION 5. Install the new EVAP canister assembly onto the vehicle. 6. Install the new fuel filler tube. 7. Install the new EVAP filter. NOTE: Install all parts in the same orientation and using the same routing as found prior to disassembly. Confirm all hoses are NOT kinked or twisted. Refer to the next page and verify the large side of the EVAP filter connects to the hose going to top of filler tube. 4/6 NTB19-037 Routing PRIOR to March 2018 EVAP filter EVAP filter Figure 8 Figure 9 Routing AFTER March 2018 EVAP filter EVAP filter EVAP filter Figure 10 Figure 11 NOTE: Routing DURING March 2018 could have either design. Before any parts are removed from the vehicle, note the EVAP filter orientation and hose routing (take a photo). Hose routing and EVAP filter orientation is critical and varies depending on production date. 5/6 NTB19-037 PARTS INFORMATION Table A DESCRIPTION PART NUMBER QUANTITY Filler tube (*) 1 Canister (*) 1 Pressure sensor 22365-1TV1B 1 Vent valve 14935-JF00E 1 Filter 14953-1LA0A 1 EPT Foam 17295-EZ30C 1 (*) Reference the Electronic Parts Catalog (EPC) to determine the part number to be ordered.
