A 50mm billet fuel filter designed for inline mounting in a performance fuel system. The 50mm body is the compact option, which matters when the filter has to fit between a surge tank and a pump, or along a chassis rail where there simply is not room for a larger housing. Machined billet construction means the housing can be opened, the element cleaned and the filter reassembled repeatedly, rather than discarded like a sealed canister filter. That makes it a far better proposition for a car that sees track use and picks up debris more quickly than a road car would. Mount it with the correct bracket so the weight is not carried by the fuel lines alone.
