🔧 Savana - Fuel Pump Module Replacement

The fuel pump on your Savana is part of an in-tank fuel pump module (pump + level sensor + strainer). Replacing it usually requires lowering the fuel tank so you can remove the lock ring and swap the module without damaging fuel lines or wiring.

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

Assumption: Your Savana uses an in-tank fuel pump module accessed by lowering the fuel tank; torque specs can vary by hardware—verify exact values in a service manual if available.

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area; fuel vapors ignite easily.
• ⚠️ No smoking, no sparks, no hot lights; keep a fire extinguisher rated for fuel fires nearby.
• ⚠️ Depressurize the fuel system before disconnecting any fuel line.
• ⚠️ Support the tank with a transmission jack; a fuel tank can shift suddenly.
• ⚠️ Disconnect the negative battery cable to prevent accidental sparks.
• ⚠️ If the tank is more than 1/4 full, siphon or drain to reduce weight.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Disconnect the battery: use a 10mm socket to remove the negative battery cable and isolate it.
• Relieve fuel pressure (simple method): remove the fuel pump relay/fuse, then start the engine and let it run until it stalls; crank 3 seconds more.
• If possible, drive until the tank is near empty to make lowering the tank safer.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Safely raise and support the van

• Use a floor jack (rated 3-ton minimum) to lift the rear, then set it down on jack stands (rated 3-ton minimum).
• Keep the floor jack lightly supporting as a backup.

Step 2: Support the fuel tank

• Position a transmission jack (specialty) under the center of the tank.
• Place a flat piece of wood (if you have it) between the jack pad and tank to spread the load. Prevents tank dents

Step 3: Disconnect the filler neck and vent hoses

• Use a flat-blade screwdriver or hose clamp pliers to loosen/remove the clamps at the tank connections.
• Twist hoses gently to break them loose; do not rip them off.
• Use a permanent marker to mark hose positions if more than one hose is similar.

Step 4: Unplug the fuel pump electrical connector

• Locate the harness near the tank/front of the tank area.
• Release the lock tab by hand or with a flat-blade screwdriver, then unplug the connector.
• If it fights you, don’t force it; check for a secondary lock.

Step 5: Disconnect the fuel lines

• Place a drain pan under the connections and wrap with shop towels.
• Use a fuel line quick-disconnect tool set (specialty) to release the quick-connect fittings (the tool slides into the fitting to release the internal spring).
• Cap or wrap the open lines with shop towels to keep dirt out.

Step 6: Remove the fuel tank straps

• With the tank fully supported by the transmission jack (specialty), use a breaker bar and metric socket to remove the strap bolts.
• Lower the straps away using a pry bar if needed (rust can stick them).
• When reinstalling later: Torque strap bolts to 50 N·m (37 ft-lbs).

Step 7: Lower the tank just enough to access the pump module

• Slowly lower the transmission jack (specialty) a few inches.
• Stop and check for anything still attached (wires/hoses/lines). Disconnect as needed using the same tools above.
• Once clear, lower the tank enough to comfortably reach the top of the module.

Step 8: Clean the area around the pump module

• Use shop towels to wipe dirt off the top of the tank.
• Cleanliness prevents repeat failures; dirt in the tank can damage the new pump.

Step 9: Remove the lock ring

• Use a brass drift punch (specialty) and dead-blow hammer to tap the lock ring counterclockwise until it releases.
• Do not use steel chisels; brass reduces spark risk.

Step 10: Remove the old fuel pump module

• Lift the module straight up carefully; angle it as needed to clear the float arm.
• Let fuel drain from the module into the drain pan.
• Remove and discard the old seal using a flat-blade screwdriver carefully (don’t gouge the tank sealing surface).

Step 11: Install the new seal and new module

• Install the new Fuel pump module seal O-ring into the tank groove by hand.
• Lightly wet the seal with clean fuel (from the old module) using shop towels; do not use grease.
• Lower the new module into the tank, guiding the float arm and aligning the index marks.

Step 12: Reinstall and seat the lock ring

• Install the ring and tap it clockwise using the brass drift punch (specialty) and dead-blow hammer until fully seated against its stops.
• Fully seated ring prevents leaks; check the ring is even all around.

Step 13: Raise the tank and reconnect everything

• Use the transmission jack (specialty) to raise the tank into position.
• Reconnect fuel lines using the fuel line quick-disconnect tool set (specialty) only if needed; otherwise push until they click.
• Reconnect the electrical connector by hand until it locks.
• Reconnect filler and vent hoses using hose clamp pliers or flat-blade screwdriver for clamps.

Step 14: Reinstall tank straps

• Position straps and start bolts by hand to avoid cross-threading.
• Tighten with a ratchet, then final tighten with a torque wrench (10-150 ft-lbs).
• Torque strap bolts to 50 N·m (37 ft-lbs).

Step 15: Restore power and prime the fuel system

• Reconnect the negative battery cable using a 10mm socket.
• Reinstall the fuel pump relay/fuse by hand.
• Prime: turn key to ON (do not crank) for 5 seconds, OFF for 5 seconds; repeat 3-4 times.

✅ After Repair

• Start the engine and let it idle while you check for leaks at the pump seal area, fuel line connections, and filler hoses.
• Verify the fuel gauge reads reasonably; a wrong reading can indicate a float arm issue.
• Test drive 5-10 minutes, then recheck for seepage/drips.
• If you have a check engine light after the repair, recheck electrical connector seating and EVAP/filler hose connections.
