We’ve been promising a summer packed with new products. So let’s get it kicked off with our new, ready-to-fit, Chevy 3×2 fuel line for small block engines.

Set at 5-1/2in carb spacing to fit Offenhauser and Edelbrock SBC 3×2 intakes, the new Big Bore fuel line (Part No. 9146-BIG) uses the classic 3-into-1 format with CNC-bent 5/16in OD 304 stainless steel lines and leak-free, ‘invisible’ furnace brazed joints. The round-bar fuel block sits down close to the manifold, matching the four degree Chevy intake angle to align visually with the valve covers. And for maximum versatility, it has 1/4NPT threads at both ends with machined 11/16in AF flats so that fittings can be tightened safely without damaging the line. The brass compression fittings (included) to attach the line into the three 97s retain the look and feel of the traditional ‘Ford Nut’ fitting.

Traditionally, all Stromberg 97s use 1/4in line, but for a Chevy tri-power, the 5/16in line looks far more appropriate. The regular 97 fuel inlet won’t accept a 5/16in line, though, so we’ve developed a new Stromberg S-jet inlet valve (part number 9564K-BIG) with the correct 5/16in seat, which must be used with this Big Bore fuel line. The 9564K S-jet, (standard on regular Stromberg 97s) must not be used with 5/16in line. Our forthcoming high cfm BIG 97 carburetor will come with the BIG S-jet as standard.

Prices are US$129.95 and £66.63 plus tax if you pay in sterling.

To help hot rodders install their new Chevy 3×2 fuel line, we’ve also launched a complementary range of 1/4NPT brass fittings. You can read about these in our next Bulletin post.

The new Big Bore fuel line and fittings are part of the Stromberg Linkage & Fuel Delivery range, available from a network of Genuine Stromberg dealers worldwide. As always, full instructions are included in the kit and further help is available via the Stromberg Tech Center at www.stromberg-97.com .
