New 6×2 fuel line solution

9080K-E 2

Say hi to our new fuel fitting. 9080K-E – Extended SuperSeat fuel hose fitting. Most people won’t need one of those – the regular 9080K fitting will do a great job. But in certain circumstances – mostly on 6×2 intakes – this is a great idea that solves a real problem.

On a typical Stromberg 97 3×2 set-up, most people mount the linkage with the sliding rod pushing the back carburetor open, but on a 6×2 progressive linkage, the sliding rods on each bank must pull the front carbs open instead, because of clearance issues with the back-bar. This WAS a problem because on a front-facing 3×2 progressive, the sliding rod (in the top adjustment hole) would rub on the underside of the center carburetor hose. You can’t move the sliding rod to a lower hole because the bottom hole is taken by the link to the back-bar. And you can’t swap them or those back-bar links hit the back carb fuel inlet! You may have seen pics of old school 6×2 progressives with slider rods bent like a big L shape to miss that center carb fuel inlet.

9080K-E simply moves the hose and clamp a little further out to leave a gap for the sliding rod to clear.  So no linkage interference and no bendy rods either.

Of course, there are rare instances on a 3×2 where the progressive linkage must pull the front carb open, and again, the 9080K-E is ready to solve the same clearance issues. Available at your local Stromberg dealer now!

5/16in fuel lines for 97s

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.

 

New Stromberg fuel fittings

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.

 

 

 

New Chevy 3×2 fuel line from Stromberg

DSC_0340We’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 .
