Just something to note:
The fuel lines pictured look like they are for DCO3 Webers on a 750 Giulietta veloce.
The fuel line for DCOE's on a 101 veloce's are different and not interchangeable. DB

Dave, as usual, is very correct. Not only are the banjo fittings different, but the line length is different. On The DCOE series, the banjo fittings are made for a slightly larger diameter brass banjo bolt that the later, non screw end fittings. In short, there are a number of variations potential buyers need to match to their specific application. As I restore these fuel lines, with modern vintage aircraft "fuel-proof" yellow hose, I get to see the variations.

Where can the modern vintage aircraft "fuel-proof" yellow hose be found Gordon?

I buy the fuel line and end furules from Geoff Ohland at Partsource. He sell it to Ferrari restoration shops. He is not happy selling to individuals, as the assembly of this type of line can represent a fire hazard.

The original line was fabric, laid up with lacquer. This line literally comes apart with modern fuels. Various additives in modern fuel dissolve the binders causing the line to leak with resultant serious fire risk.

The new line is manufactured for the vintage aircraft industry and is VERY expensive, so much so, it is sold by the mm! The appearance of the new "fuel-proof" line is very similar to the older version, except the O.D. is slightly larger, and it uses steel end fittings rather than the original aluminum.

Partsource will sell this new line to those that can assemble it in a manner to avoid leaks at the fittings. This is for liability reasons. He does not wish to sell it to individuals.

When I build a fuel line for my Alfa customers, I charge ONLY for materials, plating, shipping, and a nominal $25 cleaning charge. This is essentially a free service on my part, as I make NO GUARANTEE as to a leak proof assembly. Thus far, NONE I've built, and in service, have ever leaked, but as a liability protection, I cannot offer a guarantee.

Below is a restored line, recently completed for Keith Goring at Alfas Unlimited. This assembly is for a pair of 1960 40DCOE2's. My charge for the assembly was $125.00 less shipping and plating.

I believe I've posted other information on this fuel line, here on the BB. Imagine what the cost of materials would be for the Ferrari 330 or 275 owner. About 12 FEET of this line are used on those cars!

Thanks! I have a restored example somewhere in my photo files. The inclusion of the brass banjo bolts in your photo is VERY important. There are variations on the bolts for the different styles of connecting lines.

I also should reinforce that only end fittings with a tapered thread end should be used with fabric lines. These are no longer made, as far as I know. I have tried multiple sources both US and foreign. If you need a fabric line, you must have the correct end fittings. There are a pair of DCOE fittings pictured upper left in this photo of Weber parts just back from my plater.

Here is a comparison of the 750 and 101 lines. The owner of the 750 line did not wish to refresh his plating, just replace the leaking line.
Also a 275 GTB Ferrari is shown with multiple long lines running here and there. An expensive fuel line replacement job!

Gordon, I am in need of the DCO3 carb banjo connectors. Are you aware of any place I can buy them? Thanks, Rich

These are not available new as replicas that I'm aware of. There are BB members that dig up lines that need restoration and re-sell them to users with original application needs. Contact me by PM or e-mail and I'll give you some sellers to try.
ALSO you might find someone with an extra on the BB for Sale and wanter forum.
A recent customer in Israel, needed 101 fittings to build a yellow connector hose, and accidentally bought 750, so I KNOW there is one 750 assembly out there .... somewhere!
For DCO3, BE SURE you get correct 750 fittings!

Right Uncle, the banjo fitting on the 101 yellow line is different than the 750, and both banjos and bolts do not interchange between 750 and 101 styles. DCOE, and DCO3, each require different bolts and banjos to match the application.

Let's not make a fuss over the correct bolts for attaching the fuel line.
I have an ample supply on hand, should anyone need them.

I was out bid. Should have watched it closer. Any other thoughts about where I can get the banjo fittings? Thanks, Rich
