📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Drive until the tank is near empty; a full tank is heavy and harder to control.
• Disconnect the negative battery cable using the correct socket/wrench for your battery terminal.
• Plan to relieve fuel pressure before disconnecting any fuel line (I’ll walk you through it once I confirm your exact configuration).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm two details so I can give exact connector steps + torque specs

• Is your Wrangler a 2-door or Unlimited (4-door)?
• Are you replacing the entire fuel pump module (recommended) or the pump motor only?

Step 2: Stop here until you reply

• This job has a couple of configuration differences (tank/skid layout and line routing). Once you answer Step 1, I’ll give you the correct removal sequence and the correct torque specs for your setup.
• Tip: reply with “2-door/module” or “Unlimited/module”.

✅ After Repair

• Prime the system (key ON for 2 seconds, OFF, repeat 3 times) before cranking.
• Start the engine and check for leaks at every quick-connect and at the pump seal area.
• If the fuel gauge reads wrong, recheck the module electrical connector and that the seal isn’t pinched.
