Polyurethane is a very poor choice for handling fuel. For details go to
http://www.mcmaster.com/ and search for 5108KAC (a pdf file of properties
of various polyurethane formulations). Read it and weep.
PVC is even worse (5233KAC).
Some types of nylon (5173KAC) are good, and Teflon brand of PTFE (5239KAC)
is the best of the plastics, but lots of luck finding either material in a
large enough diameter, although Teflon lined hose is available in larger
sizes (at US$43.56 per foot for 2 inch ID).
The best choices for handling fuel and oil are the various Buna-N, and
nitrile hoses (search for "petroleum hose") and one of these is probably
what the Europa factory has supplied.

Hello,
I see where polyurethane plastic was mentioned as fuel line, and
wondered what its resistance to diesel/turbo/petrol fuels was, and whether
it has high resistance or if spares should be made for the title fuel line -
somewhere in the 2 inch diameter range.
I have a welder making up top and bottom fittings for the fuel
filler with perhaps a polyurethane line joining them. Any details gratefully
received.
20cm snow last night. At least the temp is rising to minus 5
tmoro.
