The MPI Automotive FM631DPK is the dual-battery-friendly Fuel Manager pre-filter kit, listed to fit the Isuzu D-Max and MU-X (also sold as the Holden D-Max) from 2012 on. Its mounting is laid out to share the engine bay with a second battery.

Why does the dual-battery version matter?

Engine-bay real estate is tight on a 2012-on D-Max or MU-X once a touring setup goes in, and a second cranking or auxiliary battery is one of the first things to claim that space. The FM631DPK is the kit chosen to suit a dual-battery layout, so the pre-filter mounts cleanly without fighting the battery tray. If your truck still runs a single battery, ask us which Fuel Manager kit is the better match.

What does a Fuel Manager pre-filter add?

It's a secondary diesel filter and water separator plumbed in before the factory filter. Water and fine grit picked up at the bowser get trapped and drained here rather than carried through to the common-rail pump and injectors — sensible protection on a hard-working diesel ute or wagon.

Does it fit my D-Max or MU-X?

It's listed to fit the Isuzu D-Max and MU-X from 2012 on. Treat that as the listing, not a promise — confirm your year, engine and any existing accessories with the workshop before ordering so we know it'll clear everything.

What's involved in fitting it locally?

Oak Flats Muffler Men fits these in the Illawarra. We mount the unit, plumb it into the fuel line, bleed the system and show you the drain point. The FM631DPK is supplied by MPI Automotive at a recommended retail price of $425.25 AUD.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
