Classic 3-into-1 stainless fuel line for Stromberg 97/48/81 carburetors on small block Chevy 3×2 intakes.
Designed and manufactured exclusively by Stromberg Speed Parts, TwoStep fuel lines combine super-clean looks with cool hot rod styling. The big bore 5/16in OD lines are CNC-bent for an exact fit with invisible furnace brazed joints.
The round-bar fuel block sits down close to the manifold, angled to align visually with the valve covers. For maximum versatility, it has 1/4NPT threads at both ends with machined 11/16in AF flats so fittings can be tightened safely without damaging the line.
Brass 5/16in compression fittings are supplied. A wide range of 1/4NPT brass fittings is available separately from Stromberg. Please see the Associated Products tab.
NOTE: This big bore fuel line must be used with Stromberg 9564k-BIG S-jet inlet valves. Fitted as standard on Stromberg BIG97s, they are specially designed to take 5/16in OD stainless steel line. Regular Stromberg 97 carbs take 1/4in line so you MUST update to 9564K-BIG S-jets.
Every Stromberg fuel line kit is supplied ready to install in just two simple steps and comes with full instructions. Click the other tabs for help with installation.
