Our classic stainless steel 3-into-1 fuel line (Big Bore 5/16in OD) for Small Block Chevy 3x2 intakes, combines super-clean looks with simple TwoStep installation. Designed and manufactured exclusively by Stromberg Carburetor, each kit is supplied ready to install, complete with special 5/16in Ford Nut compression fittings into the carburetor. Check out the features!
Set at 5-1/2in carb spacing to fit Offenhauser and Edelbrock SBC intakes, this kit uses CNC-bent 5/16” OD 304 stainless steel lines with leak-free, 'invisible' furnace brazed joints. The round-bar fuel block sits down close to the manifold, matching the 4 degree Chevy intake angle 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.
To help hot rodders complete the fuel line installation, a complementary range of 1/4NPT brass fittings is also available from Stromberg. Retaining the traditional hot rod look, they make it so much easier to get fuel into the block and mount a liquid-filled fuel pressure gauge. NPT fittings illustrated are not included with this kit. Please order separately.
Use 9564K-BIG Stromberg
Stromberg Big Bore fuel lines must be used with Stromberg 9564k-BIG S-jet inlet valves. Fitted as standard on Stromberg BIG 97s, they are specially designed to take 5/16in OD stainless steel line. If you have regular Stromberg 97 carburetors, you MUST update to 9564K-BIG S-jets.
