if not, you might want to at least make that part of the gauge feed line common 3/16" brake line.
Do be advised the line will be very hot so you don't fry your hand.
Also be advised that the line routing, whatever it is, should not be where it can run on sharp edges/surfaces and wear/chafe a hole which will lead to catastrophic engine failure.
Just a FYI, not to criticize.

Looks a little wet... is it leaking already?
