Technical Notes

The fuel filter is one of the most important service items on any diesel engine. Its job is to remove dirt, rust particles and water contamination from the fuel before it reaches the injection pump and injectors. Regular replacement of the fuel filter helps protect these precision-engineered components and can reduce the risk of expensive fuel system repairs.

This Fleetguard filter is manufactured to high filtration standards, making it an excellent choice for both working tractors and restored machines. Choosing a recognised premium brand helps ensure consistent filtration performance and dependable engine operation.

Before ordering, please compare the dimensions of your existing filter with those listed above. Over the years, many tractors have been fitted with alternative filter heads or conversion kits, meaning the original filter specification may have changed.

We specialise in supplying quality service parts for classic Nuffield, Leyland and Marshall tractors, including premium filtration products from trusted manufacturers such as Fleetguard.
