Hey fellas I'm trying to figure out which hose I'm suppose to tap into for the temperature gauge hose adapter. I see other folks say the upper radiator hose but im guessing the 30mm hose adapter I bought is not gonna work because the inside of my upper radiator hose does not measure 30mm id it measures 25.5mm so the adapter I bought which says 30mm is was too big for some reason. Is there something I'm missing here?
