This new fuel sampling port is custom-made for Pegasus with dual Viton seals to meet the SCCA requirement for a fuel sample port. In addition to the main Viton seal at the base of the fitting, a second Viton o-ring seals the stem to prevent leakage while drawing a sample.
The male 1/8 NPT pipe thread gives you several options for easy attachment to your fuel system (see table below).

The valve also has a nipple for attaching a 1/4 inch ID hose (not included) if needed to direct the fuel away from hot exhaust. Depending on where the valve is located, you may not need any hose at all. Hint: If a hose is needed to take a sample, remove the hose while racing to prevent the normal shock and vibration of a race car from acting on the weight of the hose and causing the valve to unseat. Zip-tie the hose to a nearby frame rail or other handy location so it will be with you at impound!
