Pump extension uses a sealed ball bearing to allow the pump shaft to run concentric to the fuel pump giving the fuel pump a longer life and has a O-ringed sealing surface to seal against the gear drive cover.
Fuel pump driveshaft is made from heat-treated steel that is black oxide finish. Fuel pump hex is .375" on the male and female end. Cam cover has a .790" hole so the racer can run a cam-sync.
The extension uses the industry standard quick release fuel pump clamp and RBS offers quick release plates for the fuel pump. Extension length is 7.00" end to end and fits RCD LS gear drives only.
