🔧 HR-V - Fuel Pump Replacement

On your HR-V, the fuel pump is inside the fuel tank as part of an in-tank pump/module assembly. Replacement is done from inside the cabin (under the rear seat access cover), but it requires careful handling of fuel vapors and the sealing O-ring to prevent leaks.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• 🔥 Work outside or in a very well-ventilated area; fuel vapors are flammable.
• 🔥 No smoking, no shop lights with hot bulbs, no grinding/sparks nearby.
• 🧯 Keep a Class B fire extinguisher nearby.
• ⚠️ Disconnect the 12V battery negative cable before opening the tank access.
• ⚠️ Relieve fuel pressure before disconnecting any fuel line to avoid spray.
• ⚠️ Keep dirt out of the tank; contamination can damage the new pump.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock a rear wheel.
• Lower the fuel level if possible; under 1/2 tank is easier and safer.
• Open the fuel door and loosen the gas cap to reduce tank vapor pressure.
• Plan to keep the cabin clean: lay shop towels around the access opening.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Open the hood and locate the under-hood fuse/relay box.
• Use a small flat-blade screwdriver to remove the fuse box cover.
• Pull the fuel pump fuse/relay (labeled for fuel pump) using needle-nose pliers.
• Start the engine and let it run until it stalls, then crank for 3 seconds to finish bleeding pressure.
• Turn ignition OFF and remove the key/fob from the vehicle area.
• Tip: This reduces spray when lines disconnect.

Step 2: Disconnect the battery

• Use a 10mm socket and ratchet to disconnect the negative battery cable and move it aside so it can’t spring back.

Step 3: Access the fuel pump service cover

• Slide the front seats forward.
• Remove the rear seat bottom cushion (it’s retained by clips). Use a trim/panel removal tool to pop the front edge clips up carefully.
• Locate the fuel pump access cover in the floor under the seat area.
• Use a Phillips screwdriver #2 (or 10mm socket, depending on fasteners) to remove the access cover fasteners and lift the cover.

Step 4: Clean and mark the pump module position

• Use shop towels to wipe dust away from the top of the pump module.
• Use a marker pen to mark the orientation of the module relative to the tank (helps prevent pinched lines on reinstall).

Step 5: Disconnect the electrical connector and fuel lines

• Unplug the pump electrical connector by releasing the lock tab using a small flat-blade screwdriver.
• Place a plastic drain pan and shop towels under the fuel line connection area.
• Disconnect the fuel quick-connect fitting using a fuel line disconnect pick tool while pulling the line straight off.
• Tip: Pull straight—twisting can damage the connector.

Step 6: Remove the pump module lock ring

• Use a brass drift/punch and small hammer to tap the lock ring counterclockwise until it unlocks.
• Lift the lock ring off and set it aside.
• Tip: Brass reduces spark risk versus steel.

Step 7: Remove the fuel pump module

• Carefully lift the module straight up. Angle it as needed to clear the float arm without bending it.
• Let fuel drain from the module into the tank for a few seconds, then move it to the plastic drain pan.
• Remove and discard the old tank seal using a trim/panel removal tool.

Step 8: Install the new seal and new pump module

• Install the new fuel pump module tank seal O-ring into the tank groove; ensure it sits flat and is not twisted.
• Lower the new module into the tank in the same orientation as your marks.
• Reinstall the lock ring and tighten it by tapping clockwise with the brass drift/punch and small hammer until fully seated and aligned with the stop marks.
• Torque to 93 Nm (69 ft-lbs) if using an appropriate lock-ring tool and torque method.

Step 9: Reconnect fuel lines and electrical

• Reconnect the fuel quick-connect until it clicks; gently pull back to confirm it’s locked.
• Reconnect the electrical connector until it clicks.

Step 10: Reinstall access cover and seat

• Reinstall the service cover and fasteners using a Phillips screwdriver #2 or 10mm socket.
• Reinstall the rear seat cushion by lining up the hooks/clips and pushing down firmly until it snaps in.

Step 11: Restore fuse/relay and battery

• Reinstall the fuel pump fuse/relay in the under-hood fuse box.
• Reconnect the battery negative cable using a 10mm socket and ratchet.

✅ After Repair

• Turn ignition ON (do not start) for 5 seconds, then OFF; repeat 2-3 times to prime the system.
• Start the engine and let it idle while you check for fuel smell or dampness at the module top and line connection.
• Take a short test drive, then recheck for leaks again.
• If you have a check engine light after the repair, scan for codes—an EVAP/fuel pressure code can appear if a connector isn’t fully seated.
