*** IN STOCK SHIPS TODAY *** For the racer that runs a Moroso Dry sump oil tank with a thread on cap time to time the O-ring under the cap that seals the cap to the top of the oil tank becomes damaged and allows a leaky mess to begin.
Fear not friends RBS carries the Moroso #97751 Buna O-ring that is fuel and oil resistant and a perfect replacement for the Moroso dry sump tank oil cap.
Carry a spare or two and make your day at the track a leak-free one.
