Maybe, but many cars out there right now driving around the streets have the fuel sample port in the engine bay.
For me, the alternative would be in the cockpit; I don't have a fuel cell or any bulkheads.
WRT street cars I think you are referring to the Schrader valve pressure test port on many fuel rails? Assuming so - all that I have seen have a screw cap, which itself seals and maybe more importantly provides significant protection against accidental / foreign object activation of the valve. If I understand that Pegasus valve correctly it would be VERY easy for a hand, tool, foreign object or crash flotsam to open the valve unintentionally.
FWIW the test port in my VW is in the engine bay, but at least it takes a wrench (one hopes!) to open it.
And none of this addresses Dayle's main point which is the proximity of the port to "hot stuff" after a session. I think that if I'm ever asked for a sample when hot I should reply "sure, in 15 minutes".
