Brackets and tanks mounted, made coolant catch can out of an aluminum automotive freon bottle
(making oil catch can/breather out of one too). Since the Facet fuel pumps do not have a check valve and I will not have both running at the same time (one will turn on with boost) I made my own check valves with no springs so there is very minimal "cracking" pressure, gravity will close them or pressure back flowing from the other pump. The check valve is to prevent fuel from just looping back through the non running pump and never make it to the carb. The "seat" for the valve was made by just using a hammer and punch with bearing in the fitting and gently persuading the fitting to take the shape of the bearing.
