⚠️ Safety & Precautions

• 🔥 Work in a well‑ventilated area away from open flames, heaters, or sparks.
• 🔌 Disconnect the negative battery cable before opening the fuel system to avoid accidental sparks.
• 💨 Relieve fuel pressure first to reduce fuel spray when lines are opened.
• 👃 Avoid inhaling fuel vapors; take breaks if you feel lightheaded.
• 👀 Wear safety glasses and fuel‑resistant gloves; gasoline can irritate skin and eyes.
• 🧯 Keep a class B fire extinguisher nearby in case of fuel ignition.
• 🚭 Do not smoke or use devices that can spark (power tools, metal hammers on steel) around open fuel.

• Turn ignition OFF and remove the key before disconnecting the battery.
• Disconnect the negative battery terminal using a 10mm socket and move the cable aside.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve Fuel Pressure

• Locate the under‑dash fuse box on the driver side and remove the fuel pump fuse (check the lid diagram; use a needle-nose pliers if needed).
• With the fuse removed, start the engine and let it run until it stalls; this uses remaining pressure in the fuel line.
• Try starting 2–3 more times until it no longer starts, then turn the key OFF.
• Reconnect the fuel pump fuse by hand or with needle-nose pliers.

Step 2: Access the Fuel Pump Under the Rear Seat

• Fold the rear seat bottoms up or forward as far as they go, following the labels on the seat latches.
• Gently lift the carpet or rear floor mat in the center area to expose the metal access cover.
• Use a Phillips screwdriver #2 to remove the screws holding the access cover.
• Lift the access cover off and set aside with the screws.

Step 3: Disconnect Battery and Inspect Connectors

• Confirm the negative battery cable is disconnected using a 10mm socket if you haven’t already.
• Locate the electrical connector on top of the fuel pump module.
• Press the tab and unplug the connector by hand; if stuck, gently help the tab with a flathead screwdriver.
• If pins look dirty or corroded, spray lightly with electrical contact cleaner.

Step 4: Disconnect Fuel Lines

• Place a few shop towels around the fuel line connections and put a small drain pan nearby.
• On each quick-connect fitting, press the plastic tabs or lift the locking clip using a flathead screwdriver.
• Pull the line straight off the pump fitting while keeping the tabs pressed; use your free hand to support the line.
• Catch any small fuel drips with towels and the pan.
• Do not twist lines excessively; they can crack.

Step 5: Remove Retaining Ring

• Clean the area around the pump with dry shop towels so dirt does not fall into the tank.
• Use the fuel pump retaining ring tool (specialty) on the ring tabs and turn counterclockwise with a 3/8" drive ratchet until the ring loosens.
• If you don’t have the specialty tool, place a plastic or brass drift punch on a ring tab and tap gently with a plastic mallet to turn the ring counterclockwise.
• Remove the ring and set it aside; inspect for cracks or damage (replace if worn).

Step 6: Remove the Old Fuel Pump Module

• Carefully lift the top of the pump module by hand; note the orientation of the outlet and connector.
• As you lift, angle the module slightly to clear the float arm while keeping it above the tank opening.
• Let fuel drip from the pump into the tank for a few seconds, then transfer the module to the drain pan.
• Remove the old O‑ring seal from the tank opening using a flathead screwdriver gently if it is stuck.

Step 7: Prepare the New Fuel Pump Module

• Compare the new pump module to the old one side‑by‑side: check height, connector style, and hose locations.
• Confirm the new O‑ring seal matches the old one in size and thickness.
• If the kit includes a new retaining ring, use that one instead of reusing the old ring.

Step 8: Install New Seal and Fuel Pump Module

• Wipe the tank opening clean with dry shop towels.
• Place the new O‑ring seal in the groove on the tank opening by hand; make sure it sits flat.
• Lower the new pump module into the tank, guiding the float arm carefully so it doesn’t bend.
• Align the pump top in the same orientation as the original (note any marks or arrows).

Step 9: Reinstall Retaining Ring

• Place the retaining ring over the pump module and ensure it engages the threads properly.
• Use the fuel pump retaining ring tool (specialty) and a 3/8" drive ratchet to turn the ring clockwise until fully seated.
• If using a plastic or brass drift punch, tap the ring clockwise with a plastic mallet evenly around the ring.
• Typical spec for this style ring is light to medium force; for reference, similar Honda rings are tightened to about 40–50 Nm (30–37 ft‑lbs). Do not overtighten to avoid damaging the ring or tank.

Step 10: Reconnect Fuel Lines and Electrical Connector

• Push each fuel line connector straight onto its matching nipple by hand until you feel and hear a click.
• Gently tug each line by hand to confirm it is locked; if loose, reseat until it clicks.
• Plug the electrical connector back into the pump until it clicks into place.
• If there were any locking clips, reinstall them by hand or with needle-nose pliers.

Step 11: Reinstall Access Cover and Interior

• Place the metal access cover back over the pump opening.
• Install the screws by hand, then snug them using a Phillips screwdriver #2. Do not overtighten; just snug.
• Lay the carpet or mat back into position and lower the rear seat into its normal position.

Step 12: Reconnect Battery and Prime the System

• Reconnect the negative battery cable and tighten the nut with a 10mm socket to snug (do not overtighten).
• Turn the key to ON (position II) without starting the engine and listen for the pump humming for 2–3 seconds.
• Turn key OFF and repeat ON–OFF cycle 3–4 times to fully prime the fuel system.

Step 13: Start the Engine and Check for Leaks

• Start the engine and let it idle.
• With a flashlight, carefully inspect around the fuel line connections and pump seal area for any wet spots or fuel smell.
• If you see a leak, shut the engine off immediately and recheck the line seating and ring tightness.
• Never use a lighter or open flame to check for leaks.

✅ After Repair

• Take a short test drive, paying attention to smooth starting, steady idle, and normal acceleration.
• After the drive, recheck around the access cover area for any fuel odor; if present, re‑inspect the pump connections.
• If the check engine light appears, use a code reader to see if any fuel system codes are stored.
• Keep the fuel level above 1/4 tank for the next few days to help cool the new pump.
