Final Fuel Filter Assembly with Lift Pump for John Deere 4045 Engine — AT443179 | 12V & 24V

This isn't just a fuel filter — it's a complete final fuel filter assembly with an integrated electric lift pump, engineered for John Deere's 4045 engine family as fitted in the 310 and 315 series backhoe loaders. The lift pump draws fuel through the filter and delivers it at the correct pressure to the injection system, ensuring clean, consistent fuel delivery under all operating conditions. Available in both 12V and 24V configurations to match your machine's electrical system. Brand new, direct-fit, and ready to install.

Why Replace Your Fuel Filter Assembly?

A clogged or failing fuel filter assembly restricts fuel flow to the injection system, causing hard starts, loss of power, rough running, and accelerated injector wear. When the integrated lift pump weakens, fuel starvation becomes a real risk — especially under heavy load. Replacing the complete assembly ensures both clean filtration and proper fuel pressure in a single service operation, saving time and protecting your injection system.
