Here is the latest controversy on [Vanagon] rubber fuel hoses:

The only rubber hose anyone can find that is Et-OH rated (J30R9, or even the R7) is sized at 5/16" I.D.

That means that it is almost 1 mm larger ID than the OEM hose, which was 7 mm.

So, there is discussion re what to do -- i.e. is a larger ID hose that is Ethanol rated better than older material hose that matches the OEM I.D.??

Certainly, rubber is flexible -- I wonder if the additional crush from clamps will accelerate cracking and hence fuel leakage at the ends of the 5/16" hose ??

I thought I'd post it here because of the high engineer density on the Pelican Porsche forms. As lendaddy noted on another thread The Samba is pretty scattered.
