🔧 Sedona - Fuel Pump Replacement

The fuel pump on your Sedona is part of an in-tank fuel pump module. Replacement involves safely relieving fuel pressure, accessing the pump module (usually under an interior access cover), swapping the module and seal, and verifying there are no leaks.

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

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area—fuel vapors ignite easily.
• ⚠️ No smoking, no sparks, no hot work lights—use an LED work light.
• ⚠️ Relieve fuel pressure before disconnecting fuel lines to prevent fuel spray.
• ⚠️ Disconnect the negative battery cable to reduce spark risk.
• ⚠️ Keep a Class B fire extinguisher nearby.
• ⚠️ Use eye protection and fuel-resistant gloves—fuel is an irritant.

📋 Before You Begin

• Park on level ground, set the parking brake, and open the fuel door to relieve tank vapor pressure.
• Work with the tank below 1/4 full if possible—less fuel = less spill and lighter module removal.
• Relieve fuel pressure: remove the fuel pump fuse/relay, start the engine, and let it run until it stalls; crank 2–3 seconds more.
• Disconnect the negative battery cable using a 10mm socket.
• Tip: Keep all screws/clips in a labeled cup.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Depressurize and power down

• Remove the fuel pump fuse/relay, then run the engine until it stalls (no fuel pressure).
• Disconnect the negative battery cable using a 10mm socket.

Step 2: Access the fuel pump service cover

• Move/remove the appropriate seat/cushion to access the floor area using a trim clip removal tool and Phillips #2 screwdriver as needed.
• Lift the carpet/sound padding to find the fuel pump access cover (metal plate) and remove the cover fasteners using a Phillips #2 screwdriver or 10mm socket (varies by cover hardware).
• Clean the area around the pump module thoroughly with shop towels so dirt can’t fall into the tank.

Step 3: Disconnect the electrical connector and fuel lines

• Unplug the pump module electrical connector using a small flat-blade screwdriver to release the lock tab (don’t force it).
• Place a catch pan (2-gallon) and shop towels under the lines to catch any fuel drips.
• Disconnect the fuel line(s) using a fuel line disconnect tool set (specialty).
• If the line uses quick-connect tabs, compress tabs with needle-nose pliers and pull straight off—do not pry on plastic fittings.

Step 4: Mark orientation and remove the lock ring

• Use a marker pen to mark the module position relative to the tank (helps reinstall correctly).
• Remove the lock ring by tapping it counterclockwise using a brass punch set (specialty) and small hammer.
• Tip: Brass reduces spark risk versus steel.

Step 5: Remove the fuel pump module

• Carefully lift the module straight up; angle it as needed to clear the float arm (the level sensor arm).
• Let fuel drain from the module into the tank, then set it into the catch pan (2-gallon).
• Remove the old tank seal O-ring from the tank opening using a small flat-blade screwdriver (gently—don’t gouge the sealing surface).

Step 6: Install the new seal and module

• Lightly coat the new seal with fuel-resistant grease and install it in the tank opening (this helps prevent pinching).
• Lower the new module in, guiding the float arm carefully so it doesn’t bend.
• Align the module using your marker pen marks.

Step 7: Reinstall the lock ring and reconnect lines

• Install the lock ring and tap it clockwise into the locked position using the brass punch set (specialty) and small hammer.
• Reconnect fuel line(s) until they click/lock; install any new fuel line retaining clips if used.
• Reconnect the electrical connector until it clicks.
• Torque to OEM spec for any service-cover or seat fasteners you removed using a torque wrench (3/8" drive, 10–80 ft-lbs).

Step 8: Reinstall the access cover and interior

• Reinstall the access cover using a Phillips #2 screwdriver or 10mm socket (whichever your cover uses).
• Reposition carpet/padding and reinstall trims/seat pieces using a trim clip removal tool and Phillips #2 screwdriver.

• Start the engine and let it idle for 2–3 minutes.
• Check carefully for leaks at the pump seal and fuel line connections using a bright light.
• Test drive 5–10 minutes, then recheck for any fuel smell or seepage.
