one really nice thing about waterboxers..
the way the fuel lines lay on the engine ..and in the van
there is almost no chance of anything rubbing or chafing on anything.
the only danger factors are pretty much .....
1. very old fuel hoses ..
3. poor workmanship done at some point in the van's life - it's not hard
to get the fuel lines on wrong actaully ..I have seen them were someone
put them together so the fuel pressure testing point was inaccessible,
for example.
3. ..that 'one spot' above the starter, on waterboxer 2WD vans.
other than those factors ..
waterboxer vanagons are arranged pretty darn nicely as far as the fuel
hoses go .
On conversions though ..
the stuff some people do !!
lol.
