🔧 Transit Connect - Fuel Pump Replacement

The fuel pump on your Transit Connect is part of an in-tank fuel pump module. Replacing it means safely relieving fuel pressure, disconnecting lines/wiring, then removing the module (either through an access panel if equipped, or by lowering the fuel tank).

Assumption: Some Transit Connect trims have an interior access panel; if yours doesn’t, you’ll lower the tank (both methods are included below).

Difficulty Level: Advanced | Estimated Time: 2.5-5.0 hours

⚠️ Safety & Precautions

• 🧯 Work outside or in a very well-ventilated area; fuel vapors ignite easily.
• 🔥 No smoking, no heaters, no drop lights with hot bulbs; use an LED work light.
• 🧤 Wear safety glasses and fuel-resistant gloves; fuel can spray when lines open.
• 🪫 Disconnect the negative battery terminal before opening the fuel system.
• 🛑 Support the vehicle with jack stands; never rely on a floor jack alone.
• ⛔ Keep a Class B fire extinguisher nearby.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the front wheels.
• Try to run the tank close to empty; a lighter tank is much safer to lower.
• Relieve fuel pressure before disconnecting any fuel line (steps below).
• Have a place ready to set the tank down (cardboard or a clean mat helps).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Open the fuel door and loosen the fuel cap to release tank vapor pressure.
• Open the hood and use the metric socket set (8mm-19mm) and ratchet to remove the battery cover if equipped.
• Disconnect the negative battery cable using a 10mm socket.
• Locate the fuel pump fuse/relay in the under-hood fuse box (diagram on the fuse box cover).
• Remove the fuel pump fuse/relay using pliers, then reconnect the negative battery cable with a 10mm socket.
• Start the engine and let it run until it stalls; crank for 3 seconds one more time.
• Disconnect the negative battery cable again using a 10mm socket.

Step 2: Raise and support the vehicle

• Use a floor jack (rated 3-ton minimum) to lift the rear jacking point.
• Set the vehicle securely on jack stands (rated 3-ton minimum) placed under solid rear support points.
• Give the vehicle a gentle push to confirm it is stable before going under.

Step 3: Check for an interior access panel (Method A) or plan to lower the tank (Method B)

• Inside the rear passenger area, look for a service cover in the floor above the tank.
• If you find a cover, use a trim clip tool and flathead screwdriver to remove it and proceed to Method A.
• If there is no cover, proceed to Method B to lower the tank.

Step 4A (Method A): Remove the pump module through the access opening

• Clean the top of the pump area using shop towels and non-chlorinated brake cleaner; dirt must not fall into the tank.
• Unplug the electrical connector and apply a tiny amount of dielectric grease on reassembly. Grease helps prevent corrosion.
• Disconnect the fuel line(s) using the fuel line quick-disconnect tool set (5/16" and 3/8").
• Mark the module position with a paint marker so the new one aligns the same way.
• Remove the lock ring using a fuel pump lock ring tool (specialty), turning it counterclockwise.
• Lift the module straight up slowly; angle it as needed to clear the float arm (the float reads fuel level).
• Remove the old seal O-ring and install the new fuel pump module tank seal O-ring.

Step 5A (Method A): Install the new pump module

• Lower the new module into the tank carefully, keeping the float arm from bending.
• Align it with your paint marker marks.
• Install the new fuel pump lock ring and tighten with the fuel pump lock ring tool (specialty) to Torque to factory specification.
• Reconnect fuel lines using the fuel line quick-disconnect tool set (5/16" and 3/8") and pull back gently to confirm they are locked.
• Reconnect the electrical connector by hand until it clicks.
• Reinstall the interior access cover using the trim clip tool and flathead screwdriver.

Step 4B (Method B): Prepare to lower the fuel tank

• Place a catch pan (3-gallon minimum) under the tank area.
• If the tank is more than 1/4 full, remove fuel using a hand siphon pump (fuel-safe) into approved fuel containers.
• Support the tank with a transmission jack (specialty) (this is a rolling jack designed to safely hold heavy parts).

Step 5B (Method B): Disconnect filler neck and vapor lines

• At the filler neck area, loosen hose clamps using a flathead screwdriver (or use the metric socket set if they are screw-type clamps).
• Disconnect EVAP/vapor lines carefully using pliers where spring clamps are used.
• Use shop towels to catch any drips.

Step 6B (Method B): Disconnect fuel lines and electrical connector

• Locate the fuel line connection(s) at the tank/pump area.
• Disconnect using the fuel line quick-disconnect tool set (5/16" and 3/8").
• Unplug the pump electrical connector by hand (use a flathead screwdriver only to gently release a stubborn lock tab).

Step 7B (Method B): Remove tank straps and lower the tank

• Keep the tank supported on the transmission jack (specialty).
• Remove the tank strap bolts using the metric socket set (8mm-19mm), ratchet, and extensions.
• Lower the tank slowly while watching for any remaining hoses/wiring that may still be attached.
• Set the tank down on a stable surface.

Step 8B (Method B): Remove and replace the fuel pump module

• Clean the tank top using shop towels and non-chlorinated brake cleaner.
• Mark the module position with a paint marker.
• Remove the lock ring using a fuel pump lock ring tool (specialty), turning counterclockwise.
• Lift the module out carefully; avoid bending the float arm.
• Install the new fuel pump module tank seal O-ring.
• Install the new module, align to marks, and tighten the lock ring using the fuel pump lock ring tool (specialty) to Torque to factory specification.

Step 9B (Method B): Reinstall the fuel tank

• Lift the tank back into place using the transmission jack (specialty).
• Reinstall tank straps and bolts using the metric socket set (8mm-19mm) and torque wrench to Torque to factory specification.
• Reconnect electrical connector by hand until it clicks.
• Reconnect fuel lines using the fuel line quick-disconnect tool set (5/16" and 3/8") and tug-test them gently.
• Reconnect filler neck and EVAP lines using pliers and a flathead screwdriver; tighten clamps firmly (do not strip).

Step 10: Prime the fuel system and check for leaks

• Reinstall the fuel pump fuse/relay using pliers.
• Reconnect the negative battery cable using a 10mm socket to Torque to factory specification.
• Turn the key to ON (do not start) for 5 seconds, then OFF for 5 seconds; repeat 3 times to prime the system.
• Start the engine and let it idle while you check underneath for fuel leaks using an LED work light.

✅ After Repair

• Confirm there is no fuel smell and no wetness at any connection.
• Test drive for 10-15 minutes, then re-check for leaks.
• If the check engine light appears, have the vehicle scanned for EVAP or fuel pressure codes (a loose vapor line is common).
• Dispose of fuel-soaked towels safely; let them dry outdoors away from flames.
