1 x SE831. Our highly recommended  In-Line Metal Cased Fuel Filter Kit with Fittings. Our own, universal,  metal cased filter kit, for fitting under a vehicle, designed so you can just  cut into your standard  1/4" fuel line and easily bolt it in wherever you wish. We suggest it is best fitted between the fuel tank and fuel pump ( to protect the £300 pump) as there is only a very crude gauze cage on the end of the pick up pipe in the tank and a roll of similar gauze in the pump base.

Equivalent XK150 Fuel Filter Ref : C13681

NOTE : This is an ESSENTIAL fitting for anyone even thinking of using a steel or original fuel tank, as steel tanks corrode badly and drop sludge into the fuel system, guaranteeing to wreck your fuel pump.
