Looks good Swoosh - nice job with the crimping. So important to have tight fitting ferrules.
How about some time lapse photos of them going yellow.
Right, crimping. No, I bought the complete setup.

A mate has got only 14 months out of a pair of these inlet rubbers before they splitI keep forgetting how long it’s been since I rebuilt the bike. It’s getting time to replacing a lot of things.

He phoned the shop and they told him "nobody else has had a problem with them"
I guess it's man made rubber that just doesn't last?
I have been told that putting footrest rubbers in a freezer bag with "waxoyl" stops them from splitting/perishing but I've not tried it myself
"I think the reason that they switched the fuel line to be moved to behind the Amal's was due to the possible blowout of the head gasket..."
Well, maybe but I think they did it simply because it was cheaper to produce.
There was a service bulletin about replacing the old crossover type fuel lines. It was changed for safety reasons.
Mine is completely brittled. I will go with AN fittings and quality hose. I will be starting with this from the tank on each side and move my way downwardshttps://www.ebay.com/itm/183253934543I found the earlier type with plastic three way connectors to be very prone to leaking and deterioration with modern fuels. The whole line goes yellow, hard and brittle.

Yes it is indeed. It is my understanding that the threads is 1/4 " BSP on both sides of the petcock. From there I will be using 1/4 Bsp to AN 6 adapterThat's a pipe connector.
The normal fitting is a nut and spigot.

Not very complicated in my opinion .AN hoses and connections are used within the drag racing industry all over the world.
When I saw the original fuel lines on my commando I have to admit I was amazed. Not even a hose clamp on the tee connections.
I guess we all spend our money were we feel its worth-
On earlier models the 3 way connectors were metal ( brass and plated ) and yes the lines went yellow and hardened but not so it became brittle .The fuel was not like today's .I found the earlier type with plastic three way connectors to be very prone to leaking and deterioration with modern fuels.

The lines go brittle because gasoline leaches the plasticizer out of the PVC tubing. Modern tubing designed for gas and oil like Tygon F-4040-A should be a better choice. The downside is the translucent yellow color and it is somewhat less flexible than regular PVC. There is also a clear version from another company (Excelon) that is supposed to be fuel resistant. I have made a set of lines from the latter, but it has only been holding fuel for about 6 months. There is also a thin walled, bright yellow tubing from Motion Pro that seems to be holding up well.On earlier models the 3 way connectors were metal ( brass and plated ) and yes the lines went yellow and hardened but not so it became brittle .The fuel was not like today's .
