Paxton supplies a T-fitting for the oil-feed line, but Patrick felt a modified factory-style fitting would work better with the vintage theme of the car. It's actually an oil-pressure sending-unit extension that was used on GT350s. Patrick drilled and tapped the extension for the oil feed line. Also shown in this photo is the Paxton-supplied boost-reference fuel pump. It allows the pump to increase fuel pressure in proportion to boost.
