🔧 CX-5 - Fuel Pump Replacement

On your CX-5, the fuel pump is an in-tank module (it sits inside the fuel tank). Replacement usually involves relieving fuel pressure, disconnecting the electrical connector and fuel line, then removing the pump module through an access cover (if equipped) or by lowering the fuel tank.

Before I give you the exact step-by-step for your CX-5 (with the correct access method), I need 2 quick details:

• ❓ Are you replacing the entire fuel pump module/sender assembly, or just the pump motor inside the module?
• ❓ Does your CX-5 have a service access panel under the rear seat (a metal cover with screws), or is there no cover?

Reply with those two answers and I’ll generate the full DIY procedure, including tools, parts, safety steps, and reassembly checks.

Difficulty Level: Intermediate | Estimated Time: 1.5-4.0 hours
