🔧 Wrangler - Fuel Pump Replacement

- ⚠️ Keep a Class B fire extinguisher within reach.
- ⚠️ Support the fuel tank with a jack before loosening any straps/skid hardware.
- ⚠️ Disconnect the negative battery cable before opening the fuel system.

📋 Before You Begin
- Park on level ground, set the parking brake, and place wheel chocks at the tires.
- Run the fuel level as low as possible. Lighter tank = safer job.
- Disconnect the battery: use a 10mm socket to remove the negative cable and isolate it.
- Relieve fuel pressure before opening any fuel line connections.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: I need 2 quick details to give exact steps + torque specs
- Tell me if your Wrangler is 2-door or 4-door Unlimited.
- Tell me if the fuel tank/skid area is stock or if you have an aftermarket skid plate/body lift (even a small lift changes access/fasteners).
Step 2: Prep while you reply (safe, no-disassembly checks)
- Use shop rags to wipe dirt from around the fuel filler area to reduce contamination.
- Use a flashlight (not a hot work light) to visually inspect under the Jeep for heavy rust on tank/skid hardware.
- Use a hand siphon pump (specialty) and drain pan to remove extra fuel if the tank is over 1/4 full.
✅ After Repair
- Cycle the key to prime the system (key ON 2-3 seconds, OFF 5 seconds, repeat 3-4 times) before cranking.
- Start the engine and check carefully for leaks at every quick-connect and at the pump module seal.
- Clear any stored codes if present and verify the fuel gauge reads normally.
