Another T120 added to the fold

Thanks for the very kind offer Chaztuna, I'll try a few more sources here first including lawnmower repair outfits, good suggestion

Dave,
Were you able to find the correct Tygon tubing locally? Amazon also has it from multiple vendors. This vendor offers it in 2 thru 5 foot lengths. See

Tygon F-4040-A 1/4" ID fuel tubing

Chaz,
Apologies for delay in getting back to you. Tygon F 4040 is available over here from several sources. What puts me off it is purely the cosmetics, it's only available in a clear yellow, which sort of looks like aged vinyl tubing (only a lot less brittle of course!)
It'd look fine on a European '70s bike I suspect, but a bit out of place on a 60s Triumph? I looked at some alternatives like versilon c-210-a, which is clear and apparently "fuel resistant", but only available in 30 metre rolls, and Motion Pro do some "premium" fuel line but suspect it's nowhere near as good as Tygon and it's £23 for 3 feet! Ho hum, will probably try some tygon when the inevitable hardening of the existing fuel lines happens and see what it looks like?

Thanks again for your help.

Dave
 
FYI, on a gravity feed fuel system, like your Bonneville, Tygon tubing will not require clamps, providing that the male fittings are barbed. The Amal fuel filter housings have barbs. Not sure if the 1970 petcock [aka fuel tap] fitting is barbed. I'd have to look at my 1970 parts catalog.

Thanks for the info Chaz, British fuel tap fittings aren't usually barbed as they consist of a separate spigot and nut, but you can get barbed type spigots, although I suspect the id of the spigot is probably a bit smaller as the nut has to fit over the barbs, if that makes sense. Anyway, probably not an issue as that isn't usually a pinchpoint in the fuel delivery.

I agree I'd jump at Tygon if it was either black or straight clear.
