Sorry, I thought they were o-rings like on the RVF. Why don't you just get the right parts to do the job? OK, they're £1.90 plus VAT each, but you know they will fit properly, and that they won't dissolve straight away!

Is there a danger of them dissolving? I didn't think fuel touched those little tubes

Theres a lot of fuel vapour around that area, and its hot and oily, you might get some blowback too. Cheap stuff might rot away.

I used 10mm ID for the ones to the sub air cleaner and the short tubes between the carbs. Seems to work well, time will tell I guess.

It certainly isn't any hotter or oilier than around the blowoff valve on the Passat, so I'm not too worried about that. You're right that silicone hose isn't approved for fuel, though. Time will tell, I guess. Besides, $5/ft isn't exactly cheap.

That would be great!

I got the silicone hose and have re-assembled the carbs. It looks promising. Once I try starting it I'll let you know how it works.
