Built to fit in congested engine bays, the vertical design raises the fill neck to create a high point in the system. Vertical tanks feature two 1/4" NPT fittings, a tapered tank bottom to a 3/4" OD tube with a beadroll, and a billet clamp for mounting to any 1-3/4" pipe. The billet clamp comes in a straight vertical or an angled style. The angled clamp is 15°  clockwise from vertical.
