A magnet assembly for attracting and retaining ferrous particles in a liquid fuel comprises a mounting 54 with a plurality of magnets 53 arranged on one side thereof in a common mounting plane, wherein the north/south axes of the magnets are parallel. At least a pair of magnets are spaced apart and have oppositely directed north/south axes. The mounting has a magnetic permeability selected such that the magnetic field on the side of the mounting is reduced, whilst the spacing between the magnets is selected such that the magnetic field on the magnet side is enhanced. The magnets are coated to prevent corrosion thereof by fuel. The assembly may be housed in a moulded plastics housing 51. Preferably, the magnets consist of neodymium and may be cylindrical. Suitably, a flat, ferrous plate can be utilised as the mounting. A fuel tank and fuel delivery module comprising the magnet assembly is also claimed. The assembly may be oriented such that the reduced magnetic field is directed towards the fuel delivery module and/or any electrical components provided therein. In another aspect, a vehicle comprises the fuel tank, fuel delivery module or a magnet assembly. |
