If you have a big horsepower, big fuel system, big flow application, chances are that you are running a serious carb to introduce that fuel into your engine. Getting the fuel into that carb in the most efficient and restriction free way is an important piece of the entire puzzle and Fragola Performance Systems understands that better than most. As proof of that understanding the company has introduced new O-Ring Boss Carburetor fittings for the new Ultra HP series of carbs from Holley and the always serious Braswell units.

These fittings were designed with flow in mind and that’s why they’re the ticket for your big horsepower hot rod or racer. Simply put, the high flow radiuses used in these babies can keep a torrent of fuel moving and not stand in the way. There’s more engineering that goes into these pieces than you can imagine and you know if Fragola is standing behind it, the performance will be just as it is advertised.
