Thanks for this great idea Deejay. I will certainly try this if my latest non-reinforced hose proves not to solve the problem (i.e. without having to disturb / remove the two fuel filler cap assemblies). I am still awaiting receipt of my new hose.

This car seems to have been 'designed' and assembled with nary a thought for future servicing needs. Thank god that most of the nuts and bolts don't have similar plain cylindrical heads!
