Need about 3 inches of pipe between the fuel filler and the tank. This pipe isn't immersed in petrol, nor does the petrol flow down this pipe, because the nozzle of the pump reaches past this pipe. The pipe is there (as far as I can guess!) to stop fumes entering the passenger compartment and to catch the occasional drip from the garage pump nozzle. Being an old Triumph, the pipe is 41 mm (1&5/8 in proper English!) and the nearest size I can find is this www.cbsonline.co.uk/product/40mm_%281_12%22%29_Duct_Hose_PVC_DCTHS40So apologies for the rambling thread, but will this type of PVC stand up to petrol? And have this for thanks (No race drivers were harmed in the making of this picture)

Breather hoses really should be proper fuel-rated hose. Other things will work for a little while, but they generally break down within a year or two. On Beetles, there's a short piece of large-diameter breather hose like you describe. A lot of people use heater hose, but it disintegrates fairly quickly. I searched for quite a while and eventually managed to find some fuel rated hose in the right diameter. I had to call around different hose suppliers with the diameter that I needed, and eventually found it at an engineering supply shop.

Is this the standard setup or have you altered it in some way?
Would have thought that a shout out on Triumph forum would net you a used one and they seem pretty durable? Failing that a call to TD Fitchetts, Earlpart or Chris Witor would probably get a good result.
Otherwise I'd be wandering down to my local scrappy looking for a suitable donor or trying my local farm supplies or hydraulic specialist (though with those I'd be concerned about material compatibility).
Various silicone hose suppliers also as mentioned. Not all are suitable for immersion in petrol though, especially with ethanol content and it will getting constant wetting whilst on the move with a fullish tank.
Cheers

To be honest, it's just that originals are a proper PITA to fit!

Only if you bolt the tank in before you start trying to fit it....... Need to get it in place while positioning the tank.

?? Removed and refitted mine a couple of times relatively recently. Don't remember any aggro at all.
Contrast to removing and especially refitting the Vitesse one which always reduces me to a gibbering rage while trying to rediscover the exact sequence of moves that lets it fit into place.......(though I've not done this for quite a few years the horror remains fresh!)

While we're on the subject, I wonder how resistant to Ethanol these original hoses are?

Me too. So far I've not had any problems with this part. I have had problems with some of the new hose (smaller dia) I put in when I did the EFI conversion. No actual leaks or falling to bits but serious petrol stink due to porosity.
I've changed the 8mm stuff in the pressure and return lines to R9 spec (correct for ethanol containing petrol) but still need to find some R9 spec 10mm for the pump suction side.
Interestingly the Vitesse has mostly the older R6 spec stuff and this seems to be ok though nearly all the pipework is outside the car.

Might have what you need. On my 1300FWD which I am breaking there is a flexible rubber section in the filler neck about 4 maybe 5 inches long. Its in good condition and proper fuel rated hose.

I'll measure it tomorrow but there is a good chance its the same as both are Triumph models and they did like to use the same parts between models as much as possible.
