We recently launched some new fuel fitting parts so you can make 5/16in fuel lines for Stromberg 97s. While the stock early Ford 1/4in OD hard lines are great-looking for a typical flathead motor, many people like the thicker lines for Chevys and other applications. This includes us, of course, as our recently launched 9146-BIG 3-into-1 fuel line uses 5/16in OD stainless hard line. And more than that, all our forthcoming new Stromberg BIG 97s are 5/16in hard line compatible. You can see in these pictures how the BIG S-jet seats the 5/16in line and what happens when you try it in the regular S-jet – it leaves no seat for the ferrule. Click to enlarge.
Today we got a tech enquiry from Shane Dale in Australia that covers this very question, so we thought we’d share it here:
Hello, I have three new 97’s that I purchased in 2011 and am finally getting around to fitting up. I will be bending my own 5/16 OD hard line and was wondering what size fitting will screw into the carb? I purchased three 9180K’s and started hand screwing them but stopped quickly as it went tight.
Hi Shane, A couple of issues here. Firstly, 9180K is our 1/4NPT hard line adapter so the tapered NPT thread won’t fit into the S-jet, which is 1/2in UNF – that’s why it went tight. And as you worked out, regular Stromberg 97 inlet valves (needle & seats) were designed with a 1/4in pocket to take the line and the angled seat is positioned so the brass ferrule can compress properly to seal on the 1/4 pipe. If you put 5/16in line in, it doesn’t sit in the hole properly and covers most of the angled ferrule sealing surface. The good news is, we recently developed a new S-jet inlet valve for our 97s specifically for 5/16th line, and we also just launched a pack of compatible ‘Ford Nut’ style compression fittings for them. You need 3 x 9564K-BIG (the S-jet inlet valve) and just one pack (3 nuts and 3 ferrules in a pack) of 9081K-BIG (the Ford Nut for 5/16th line).
All the best, Stromberg Tech.

Well, we promised a summer of new product launches and it continues with traditional phenolic spacers for your Stromberg 97 carburetors, plus a complementary extended intake manifold stud kit.
Tried buying a ‘real’ phenolic spacer lately? Truth is, the real old-school phenolics are becoming harder to find and those orange colored plastic spacers we’re seeing for sale just don’t seem right on a traditional hot rod, if you ask us.
Manufactured in California, USA exclusively for us here at Stromberg Carburetor, the new 1/4in spacers are cut from Natural Canvas Grade C Phenolic sheet with the classic brown color. The full kit (part number 39447K) includes two gaskets – used above and below the spacer – and work with 97s and other 3-bolt, 2-barrel carburetors like the Holley and Edelbrock 94s, of course..
Made from layers of canvas impregnated with synthetic resin binder, the benefits of phenolic sheet for carburetor spacers are well documented. Reducing heat transfer from the intake manifold to the carburetor, they can promote a cooler, denser fuel mixture for more horsepower. If you live in a hot climate and suffer from fuel percolation, you’ll be well acquainted with the heat insulation benefits too. If you’ve got a two-barrel carb with an aluminum base casting, these should really help.
Carb spacers need extra long intake studs of course, so we’ve also launched an extended manifold stud kit (Part number 89067-E) – three 1/4in longer studs with stainless steel nuts and lock washers.
39447K Phenolic carburetor spacer – 1/4in US$25.95 £16.63 + tax
89067-E Extended manifold stud kit. US$13.95 £8.29 + tax
Stromberg phenolic carburetor spacers and extended intake manifold stud kits are available now from our worldwide Genuine Stromberg dealer network, and help with installation is available from Stromberg by email or via the Stromberg Tech Center at www.stromberg-97.com.
To complement the launch of our new Big Bore 3×2 fuel line (Part No. 9146-BIG) for small block Chevy intakes, we have introduced a range of Stromberg fuel fittings. Some are specific to Stromberg products, like the new 9564K-BIG S jet for 5/16in line. Others are just handy, traditional looking 1/4NPT brass fittings with stacks of uses around your fuel system. Like getting fuel into and out of a traditional hot rod fuel block. Or mounting a liquid-filled fuel pressure gauge. As you can see in our last picture, these fittings can be used with our 9146-BIG fuel line, which has 1/4NPT threads at each end of the fuel block.
Here’s a quick round-up of what’s available:
9182K 1/4NPT hose fitting. The most common hose barb for traditional style fuel blocks. Perfect for the Stromberg 9146-BIG 3×2 line for Small Block Chevy, but NOT to be used in your Stromberg 97 inlet valve (use 9080K instead).
9181K 1/4NPT hex head plug. If you’ve got a traditional style fuel block with 1/4NPT ports, and need to block one off, this will get you straight out of trouble.
9180K 1/4NPT hard line adapter. If you want to fit a 5/16in OD hard fuel line into a 1/4NPT fuel block, this is the fitting you need.
9179K 1/4NPT to 1/8NPT bush. This male to female reducer bush is a must have item if you’re fitting a liquid-filled fuel pressure gauge (which typically comes with a 1/8NPT thread) to your 1/4NPT fuel block port.
9178K 1/4NPT 90deg elbow. Our 1/4NPT male to 1/4NPT female 90deg elbow solves many fuel line problems, like fitting a liquid-filled fuel pressure gauge to your fuel block so you can read it! – perfect for the Stromberg 9146-BIG 3×2 line for Small Block Chevy.
9081K-BIG Ford Nut compression fittings (x 3) for bigger 5/16in hard line. Has the correct 1/2in x 20 UNF thread for Stromberg inlet valves, but must ONLY be used with Stromberg 9564K-BIG S-jet inlet valves (available now from Stromberg dealers). Regular 97 inlet valves only take 1/4in hard line.
9564K-BIG A specially designed S-jet inlet valve for use with 5/16in OD fuel lines – eg. 9146-BIG 3×2 line for Small Block Chevy. Fitted as standard on all Stromberg BIG 97s, it accepts regular 9080K Superseat hose fittings, but for hard line, it must be used with 9081K-BIG 5/16in Ford Nuts.
