🔧 SRX - Fuel Pump Replacement

On your SRX, the fuel pump sits inside the fuel tank as a complete “pump module” (pump + level sender + strainer). Replacement is mostly about working safely with gasoline, relieving fuel pressure, disconnecting the lines, and swapping the module without damaging the tank seal.

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

Assumption: Some SRX builds have a service access cover under the rear seat; if yours doesn’t, you’ll follow the “Tank Drop” path below.

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area—gasoline fumes are highly flammable.
• ⚠️ No smoking, no heaters, no grinding/sparks, and keep a fire extinguisher nearby.
• ⚠️ Relieve fuel pressure before opening any fuel line to prevent fuel spray.
• ⚠️ Disconnect the negative battery cable before opening the tank/module.
• ⚠️ Use jack stands—never rely on a floor jack alone.
• ⚠️ Clean the area before opening the tank to keep dirt out of the fuel system.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the front wheels.
• Run the fuel level low (about 1/4 tank or less). A lighter tank is much easier to handle.
• Relieve fuel pressure: remove the fuel pump fuse/relay, start the engine, and let it stall; crank for 3 seconds more.
• Disconnect the negative battery cable using a 10mm socket.
• Tip: Take photos of connectors and line routing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure (double-check)

• Use a fuse puller or needle-nose pliers to remove the fuel pump fuse/relay.
• Start the engine and let it run until it stalls, then turn the key off.
• Use a 10mm socket to disconnect the negative battery cable and secure it so it can’t spring back.

Step 2: Choose your access method

• Try the under-seat method first: remove the rear seat bottom using a plastic trim removal tool set and your hands (most cushions pop up from front clips).
• If you see a round/oval metal cover (service access), continue to Step 3.
• If there is no cover, skip to Step 9 (Tank Drop method).

Step 3: Open the fuel pump service cover (if equipped)

• Use a Torx T20 bit or 10mm socket (varies by cover fasteners) to remove the access cover screws/bolts.
• Use shop rags to wipe dust away so dirt doesn’t fall into the tank.

Step 4: Disconnect the electrical connector and fuel lines

• Unplug the pump electrical connector by releasing the lock tab using a plastic trim removal tool set.
• Place a drain pan and shop rags under the lines.
• Use the fuel line disconnect tool set (specialty) to disconnect the quick-connect fuel line(s).
• Tip: Pull straight—don’t pry the plastic fittings.

Step 5: Mark the lock ring and module orientation

• Use a permanent marker or paint pen to mark the lock ring and tank so you can reinstall in the same position.

Step 6: Remove the lock ring

• Use a fuel pump lock ring removal tool (specialty) to turn the ring counterclockwise and remove it.
• If you don’t have the ring tool, use a brass punch and small hammer to tap the ring loose (brass reduces spark risk).

Step 7: Remove the fuel pump module

• Carefully lift the module out by hand, tilting as needed to clear the float arm (fuel level sender).
• Use shop rags to catch any dripping fuel.
• Remove the old tank seal (O-ring) using a non-sparking plastic scraper.

Step 8: Install the new module and seal

• Lightly lubricate the new seal with clean fuel and set it in place by hand (don’t twist it).
• Lower the new module in, keeping the float arm from bending.
• Install the lock ring and tighten using the fuel pump lock ring removal tool (specialty) until it fully seats and aligns with your marks.
• Reconnect the fuel lines using the fuel line disconnect tool set (specialty) and verify they “click” and lock.
• Reconnect the electrical connector and apply a tiny amount of dielectric grease to the seal area of the connector (not the terminals).

Step 9: Tank Drop method (if no access cover)

• Raise the rear of the vehicle using a floor jack (rated 3-ton minimum) and support it with jack stands (rated 3-ton minimum).
• Support the fuel tank with the floor jack (use a block of wood to spread the load).
• Disconnect the EVAP/fuel lines as needed using the fuel line disconnect tool set (specialty) and catch drips with a drain pan.
• Disconnect electrical connectors at the tank using a plastic trim removal tool set.
• Remove the tank strap bolts using the appropriate socket set 8mm-18mm.
• Torque to 25 Nm (18 ft-lbs) when reinstalling tank strap bolts.
• Lower the tank slowly with the floor jack and move it enough to access the pump module on top.
• Perform Steps 5-8 to replace the module, then raise the tank back into place and reconnect everything.

Step 10: Reinstall covers/seat and reconnect battery

• Reinstall the service cover using the original fasteners with a Torx T20 bit or 10mm socket (snug, do not strip).
• Reinstall the rear seat bottom by aligning clips and pushing down firmly.
• Reconnect the negative battery cable using a 10mm socket and Torque to 15 Nm (11 ft-lbs).

✅ After Repair

• Turn the key to ON (engine off) for 5 seconds, then OFF for 5 seconds. Repeat 3 times to prime the system.
• Start the engine and let it idle for 2 minutes while you check for leaks at the pump top and fuel line connections.
• If the check engine light comes on, use a scan tool to read codes (often EVAP-related if a line isn’t fully seated).
• Test drive for 10-15 minutes, then recheck for fuel smell/leaks.
