[, petrol is too expensive for it to be leaking out!
that's not the reason to worry about it Tunnie.
if you can smell petrol, it means there are fuel fumes around... and it's the vapour that's dangerous... the liquid itself is actually relatively safe (as things that can go bang go.... or for a given value of "safe" )
sorry I was thinking about what caused fumes in my Sennies... which largely happened in the 12 valve ones.. as graham spotted ....... forgot yours is 24 valve and has a different injector system. I'm sure we had something similar in the 24 valve version as well though... I'll have to dig out my old notes and manuals if i can find them... and havea quick memory refresh....
but it's still worth checking every single joint and length of fuel line...
the thing is, it need not necessarily be a big, and obviously wet, leak... just not being tight enough might allow vapour to escape....
the 12 valve flaw was basically as the rubber aged... the ends harden up and it ceases to provide a flexible seal under the clamp..... and the injector rail, being at fairly high pressure, will encourage anything to leak where ever it possibly can. and it did.....
just seeping slightly is potentially a more insidious danger than pissing out everywhere... as you may be inclined to leave it for now as it SEEMS less important.
remember , it's not the liquid fuel that explodes in the cylinder , it's fuel vapour and air mixed.
(of course pissing out onto a hot manifold is going to create a LOT of vapour... so that trumps the "subtle leak" easily.......)
