I have noticed it leaks a small amount of fuel (1 drip per 5 seconds). I am going to talk t my instructor about it but wanted to know what it was called. I am not seeing it in the fuel system diagram.
Updates: I believe it is a part of the electric auxiliary fuel pump, but want any input.
The aircraft is a Cessna 172R made in 1997.
It is 100LL that is dripping.
