Dashboard f/p gauge - kewl! I'm in the process of working out an elegant way of connecting and disconnecting an under bonnet (hood) f/p gauge without having to undo the cold start injector line or other crude and messy arrangements. Will put a barbed T in the cold start injector line and a click fitting with a tap. Mate the pdf is a goldmine - thanks for sharing it.
