Pump extension is made from billet aluminum and is black anodized for corrosion protection. It uses Teflon O-rings to insure proper sealing between the three sections as well as a heat treated steel fuel pump driveshaft with a 3/8" female hex on the pump end and a 3/8" male hex on the camshaft end.
Anodizing is faded but all the threaded holes are in good shape and the bearing feels smooth.
