4M fuel filter

They maybe just tolet rolls the bigger the aplication the more rolls you put in!

Check the number marked on the element, and places like Repco, or Bearing service should be able to cross reference it for you. Pyshical dimensions might be another guide for you too.

4M fuel and oil filters use plain old dunny rolls. To be more specific they use 400 sheet x 2ply rolls. Any brand will do.They are an extremely tight fit but do go in with a bit of persuasion
Had them fitted to my old MQ short wheel base Patrol 3.3 diesel 24 volt model(round 80-81 vintage). Single roll on the fuel and a double for the oil.

4M filters were designed to ASSIST NOT REPLACE existing filtration sytems already fitted to the vehicle therefore can be removed (if fitted correctly) without changing the original setup. Fuel filter INLINE with original and oil on a bypass system.
Instead of changing your oil every 5000 k's (diesel) you changed the dunny roll/s, the original filter at 10000 and the oil at 20000 k's intervals (normal usage). Can't remember the fuel filter change time but for the price of a few dunny rolls, who cares!
The oil certainly lasted longer than with standard type filters and it was possible to check some conditions of the engine depending on the shape of the "roll' when removed eg; carbon buildup, fuel dribble past injectors etc.
As stated earlier, they were already on my SWB Patrol when purchased and I had that car for approx 12 years and can assure you they do work. And the dunny rolls didn't break down when immersed in oil of diesel (they are in a confined space).
So, if you haven't tried them don't knock them.
And no I'm not nor never was a rep for the company.
