Designed and manufactured exclusively by Stromberg
Carburetor, TwoStep Big Bore fuel lines are supplied ready to install,
complete with special 5/16in Ford Nut style 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 5/16in 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 matching range of chromed 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.

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.
