Rumblefish 360, no accuasations intended, your pic shows exactly what I suggested to 93ragtop, and I'll have to set mine up the same. Did your intake come new with the hose nipple hole that you are using alredy at 3/8"? Ours is 1/8 at that far passenger position. You said you didn't have to drill and tap that one? But you did have to drill and tap for stock temp sending unit? Sorry for the confusion. Pic of my new 7577.
