🔧 Canyon - Fuel Pump Replacement

On your Canyon, the fuel pump is part of an in-tank fuel pump module. Replacing it usually means lowering the fuel tank (most common OEM-style method) or lifting/removing the bed (alternate method) so you can access the pump lock ring on top of the tank.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

⚠️ Safety & Precautions

• 🔥 Gasoline is extremely flammable—work outside or in a well-ventilated area, no smoking, no shop heaters with open flame.
• 🧯 Keep a Class B fire extinguisher nearby.
• 🔋 Disconnect the negative battery cable before opening the fuel system.
• 🛑 Relieve fuel pressure before disconnecting any fuel lines to avoid high-pressure spray.
• 🧰 Support the fuel tank with a transmission jack (or wide jack platform). A floor jack alone can slip.
• 👓 Wear safety glasses and fuel-resistant gloves.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the front wheels.
• Run the fuel level as low as possible. A lighter tank is much safer to handle.
• Relieve fuel pressure: remove the fuel pump fuse/relay, start the engine, and let it stall. Crank 2–3 seconds more. Then turn key OFF.
• Disconnect the negative battery cable using a 10mm socket.
• A “quick-disconnect” fitting uses an internal clip. You’ll use a fuel line disconnect tool to release it without breaking the line.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the truck

• Use a floor jack to lift the rear safely.
• Set the frame on jack stands and keep the floor jack available.

Step 2: (Recommended) Reduce fuel weight

• Use a siphon pump to remove as much fuel as you can into an approved fuel container.
• Use shop rags to catch spills and a drain pan under the work area.

Step 3: Disconnect filler neck and EVAP hoses

• At the fuel door area/under bedside, loosen clamps using a socket set or flat trim tool (varies by clamp style).
• Disconnect the large filler hose and smaller vent/EVAP hoses.
• Plug hoses with clean rags to keep dirt out.

Step 4: Support the fuel tank

• Position a transmission jack under the center of the tank and snug it up.
• Use a flat board on the jack pad.

Step 5: Lower the tank slightly to access the top connections

• Remove tank shield(s) if equipped using a socket set and ratchet.
• Remove the fuel tank strap bolts using a socket set, ratchet, and extensions.
• Slowly lower the tank a few inches with the transmission jack so you can reach the electrical connector and fuel lines on top.
• Torque to 25 Nm (18 ft-lbs) for tank strap bolts (if your hardware spec differs, follow the spec for your bolts).

Step 6: Disconnect electrical and fuel lines on top of the module

• Unplug the fuel pump electrical connector using a flat trim tool to release the tab if needed.
• Disconnect the fuel feed/return line(s) using a fuel line quick-disconnect tool set.
• Disconnect any EVAP line(s) the same way, as equipped.
• Have shop rags ready—some fuel will drip.

Step 7: Lower and remove the fuel tank

• With all lines free, lower the tank fully using the transmission jack.
• Slide the tank out from under the truck.

Step 8: Clean the area around the fuel pump module

• Wipe and clean the top of the tank with shop rags so dirt can’t fall inside.
• Cleanliness prevents repeat pump failure.

Step 9: Remove the lock ring and remove the pump module

• Use a brass punch and hammer to tap the lock ring counterclockwise until it releases.
• Lift the module out carefully—tilt as needed to clear the float arm.
• Remove the old tank seal (O-ring) by hand.

Step 10: Install the new seal and new fuel pump module

• Install the new tank seal (O-ring) into the groove on the tank opening.
• Lower the new module in gently, keeping the float arm from bending.
• Reinstall the lock ring and tap clockwise with the brass punch and hammer until fully seated on its stops.

Step 11: Reinstall the tank

• Lift the tank back up with the transmission jack.
• Reconnect the electrical connector and all fuel/EVAP quick-connect lines by hand until they click.
• Raise the tank fully and reinstall straps using a socket set and ratchet.
• Torque to 25 Nm (18 ft-lbs) for tank strap bolts (verify if your strap fasteners specify differently).
• Reinstall any shields using a socket set and ratchet.

Step 12: Reconnect filler/vent hoses and battery

• Reconnect filler and vent hoses and tighten clamps using a socket set or flat trim tool (clamp dependent).
• Reconnect the negative battery cable using a 10mm socket.

Step 13: Prime the fuel system and check for leaks

• Turn key to ON (do not start) for 5 seconds, then OFF for 5 seconds. Repeat 3–4 times.
• Start the engine and let it idle.
• Inspect every connection for wetness/smell using safety glasses and a bright light.

Alternate Access Method (If dropping the tank is not practical): Bed removal/lift

• This method can give top-of-tank access by removing/loosening the bed bolts and unplugging tail lamp harness connectors.
• Use a socket set (13mm–18mm typical), extensions, and 2–3 helpers to lift/slide the bed.
• Then perform lock ring/module steps from above using a brass punch and hammer.

✅ After Repair

• Confirm the fuel gauge reads reasonably and the truck starts quickly after priming.
• Recheck for leaks after a short 5–10 minute drive.
• If a check engine light appears, scan codes—an EVAP line not fully clicked in is a common cause after tank work.
