[urq] fuel smells

[Martin Pajak]

I had a small pin hole leak in the plastic line from the pump to the
accumulator.
It was so tiny that it would mist i.e. no puddle on the ground, once the
pressure was down no leak could be seen.. only way I noticed is right after
shutdown I got down and saw it.
Obviously it would also give me a big hot start problem if the car was
sitting hot for more than 15min.

Hope this helps.

Subject: [urq] fuel smells

I keep noticing a whiff of petrol from my car. Most noticeable at the
nearside rear wheel arch – the one nearest to the fuel pump. There is no
sign of a leak at all. I mentioned it at it’s MOT test yesterday and the
tester had a real good search and could find no evidence of a leak. This is
also roughly where the tank vent pipe emerges (the pipe vents to atmosphere
via the big grommet beneath the takn that also serves the feed and return to
the tank. There is no charcoal fume trap or any other valve in this vent
pipe. It simply vents direct form the top of the tank. Is it because the car
is not doing any miles and so doesn’t have air passing around it so often
that means I notice it more or is there something I cant see that is causing
the smell? Should the vent pipe have a trap of some kind? Any
recommendations? Anyone suffered the same and subsequently solves it? Will
be interested in any suggestions/advice/guidance.
All the best
Keith
