🔧 Canyon - Fuel Pump Replacement

On your Canyon, the fuel pump is part of an in-tank fuel pump module. Replacement usually requires either lifting/removing the truck bed (often easiest access) or lowering the fuel tank (more work on the ground).

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

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area; fuel vapors are flammable.
• ⚠️ No smoking, no flames, no hot work lights near the tank.
• ⚠️ Relieve fuel pressure before disconnecting any fuel line.
• ⚠️ Disconnect the negative battery cable before opening the fuel system.
• ⚠️ Support the bed/tank securely; never rely on a jack alone.
• ⚠️ Keep a Class B fire extinguisher nearby.

📋 Before You Begin

• Park on level ground, set the parking brake, and install wheel chocks.
• Get the fuel level as low as possible; a light tank is much easier to handle.
• Open the fuel door and loosen the gas cap to release tank vapor pressure.
• Plan your access method: Bed-off (recommended) or Tank drop.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Open the hood and locate the underhood fuse/relay box.
• Remove the fuel pump fuse/relay using pliers (or your fingers if it pulls easily).
• Start the engine and let it run until it stalls; crank for 2-3 seconds more to help bleed off pressure.
• Turn the key off.

Step 2: Disconnect the battery

• Use a 10mm socket and ratchet to disconnect the negative battery cable.

Step 3: Choose your access method

• Bed-off method: Typically faster and gives clean top access to the pump module.
• Tank-drop method: Works if you can’t lift the bed, but needs more under-truck work.
• If your tank is over 1/2 full, bed-off is easier.

Step 4A: Bed-off method (access the pump from above)

• Remove the tail lamp assemblies using a Torx driver set (if equipped) or socket set (metric) 8mm-21mm depending on fasteners you have.
• Disconnect the tail lamp electrical connectors by hand.
• Remove bed-to-frame bolts using a breaker bar and socket set (metric) 8mm-21mm.
• Remove fuel filler neck screws/clips at the bedside using a flathead screwdriver and trim clip removal tool.
• With helpers, lift the bed rearward/up enough to access the top of the fuel tank (or fully remove the bed).
• Reinstallation: use a torque wrench and Torque to factory specification for bed bolts. Don’t guess bed bolt torque.

Step 4B: Tank-drop method (lower the fuel tank)

• Raise and support the truck using a floor jack (rated 3-ton minimum) and jack stands (rated 3-ton minimum).
• Support the fuel tank with a transmission jack.
• If equipped, remove any tank skid plate using a socket set (metric) 8mm-21mm and ratchet.
• Disconnect the filler neck/vent hoses using flathead screwdriver (hose clamps) and pliers (spring clamps).
• Unplug the fuel pump module electrical connector by hand.
• Disconnect fuel supply/EVAP lines using a fuel line quick-disconnect tool set. Expect a small fuel spill.
• Remove the tank strap bolts using a socket set (metric) 8mm-21mm and ratchet, then lower the tank slowly.
• Reinstallation: use a torque wrench and Torque to factory specification for strap bolts.

Step 5: Clean the top of the tank

• Use shop towels to clean dirt off the top of the tank around the pump opening.
• This helps keep debris out of the tank.

Step 6: Remove the fuel pump lock ring

• Mark the module’s orientation to the tank using a flathead screwdriver (scratch mark) so the new one goes in the same way.
• Use a fuel pump lock ring tool (specialty) to turn the lock ring loose.
• If you don’t have the ring tool, use a brass punch and dead-blow hammer to tap the ring loose carefully (brass helps reduce spark risk).

Step 7: Remove the pump module and seal

• Lift the module out slowly, angling as needed to clear the float arm.
• Have a drain pan ready to catch fuel drips.
• Remove the old tank seal (O-ring) by hand and discard it.

Step 8: Install the new seal and fuel pump module

• Install the new fuel pump module tank seal (O-ring) into the tank groove by hand.
• Lower the new module into the tank in the same orientation as the original.
• Install the new fuel pump lock ring, then tighten using the fuel pump lock ring tool (specialty).
• Use a torque wrench and Torque to factory specification for the lock ring if your tool supports torque.

Step 9: Reconnect lines and wiring

• Reconnect fuel/EVAP lines until you feel/hear a click; use the fuel line quick-disconnect tool set only if needed.
• Reconnect the electrical connector by hand until fully seated.
• Reinstall filler neck/vent hoses using pliers or flathead screwdriver (depending on clamp type).

Step 10: Reassemble (bed or tank)

• If bed-off: set bed back in place, start all bolts by hand, then tighten with a ratchet and finish with a torque wrench to factory specification.
• If tank-drop: raise the tank with the transmission jack, install straps, tighten with a ratchet, then finish with a torque wrench to factory specification.
• Reinstall skid plate (if equipped) using a socket set (metric) 8mm-21mm and ratchet, then Torque to factory specification.

Step 11: Restore power and prime the fuel system

• Reinstall the fuel pump fuse/relay by hand.
• Reconnect the negative battery cable using a 10mm socket and ratchet.
• Turn the key to ON (engine off) for 5 seconds, then OFF for 5 seconds; repeat 3-4 times to prime.

✅ After Repair

• Start the engine and let it idle for 2-3 minutes.
• Inspect for leaks at the top module area (if bed-off) and at all fuel line connections (both methods).
• Road test gently, then recheck for fuel smell or seepage.
• If a check engine light appears, read codes; EVAP line connectors are easy to leave slightly unseated.
