“Attractive unit, don’t know if it’s durable because I can’t use it on a 5/16 fuel feed. The 5/16 measurement is taken from the outside edge of the barbs on the in and out feed of the filter which means it is not even tight in a 5/16 fuel line and the actual fuel feed is 3-3.5mm making it unusable on high performance engines requiring a 5/16 flow rate. Attractive unit though.”
