If you already have Stromberg banjos (9082K or 9083K) and want to add a fuel pressure gauge to your line, right at the carburetor, this is the bolt for you. The 1/8th NPT hole in the end of the banjo bolt accepts your hot rod fuel pressure gauge, which is all the more important with Stromberg 97 carburetors because you need to ensure 2.5psi max. On Ford flathead applications, check for gauge clearance on your top radiator hoses. Note: To provide safe clearance with a 3×2 progressive linkage, banjo fittings must be used with our stainless banjo spacers (9086K). Will not provide clearance for progressive linkages on 6×2 systems. All direct linkages clear OK without spacers.
