Air gap intake and heater hoses

Barbed fittings: Good or bad?

As per the attached thread, I was working through this same issue last month and turned to FABO to decide on whether to use barbed brass fittings like that. I ended up opting for the stock style nipples from Mancini, as posted above in post #20.

Not sure why the piece you just bought wouldn't work fine, capacity wise; it's the same as stock. With my six banger, a new heater core and that size (but stock) fitting, I could have cooked a turkey in the car.
