Fuel pressure testing port, like what is on a lot of cars and trucks.  It's a nice addition.

Phil, is there a way to retrofit that?

Doe's that take a special type gauge or will a tire pressure gauge be sufficient?

It allows use of standard auto testing equipment.

No easy way to retrofit, but it would be a novel idea for the aftermarket to make a replacement fuel line and add that fitting.

those fittings are available as a Tee .......  cut the existing line and put a Tee in

Looks like a refrigeration schrader.
