s2 roadster 1969 Boot always smells of fuel

[katalan]

I still have fumes in boot , have tried everything . Mechanic took out charcoal filter and has made the problem worse . I can not find any info on what and where the pipes should go to . The fuel tank has been tested , new gasket all new fuel lines , new pump , tried fibre and aluminium washers ,any advice would be much appreciated Thanks

It is often caused by the top cover plate not fully tightening down on the gasket. The holes into which the small screws are usually blind ones, and if the screws are even fractionally too long they bottom out in the holes and give the illusion that the plate is tightened down when in fact it is not.

Thanks but do not think this is the problem as the fuel tank has been out and tested . I think it was a mistake to have the charcoal filter taken out so would like to replace , but as I did not remove I have no idea where the four connections on the boot mounted canister are meant to go . Thanks .

Hello, and welcome. Alan is it? We like names here - in my case so people know who to be annoyed at :-)

Plus if this area leaks then assuming you've actually looked at it you can see the stains (I think it's the fuel sender holes that are blind, the large plate holes are not).

The boot-mounted thing is not a charcoal canister, it's an expansion tank. The charcoal jobbie is down by the battery. The late tanks have numerous extra breathers, any one of which could be loose and if the header tank is removed they should be blocked off except the highest one (IIRC) to replicate the old-style breather. Your fuel cap may not have a hole in it and this causes fuel to pressurise sometimes. If you've tinkered with the emissions stuff you'll be needing a vented cap, depending what was done. Look on www.jag-lovers.org for a thread this week on breathers. A guy called Ralph Knutsen ('RGK') mentions a link to a bulletin which shows all the layout of the pipes etc.

Pete, thanks for your input ,I think you have put me in the right direction . My car is ex UK and therefore does not have charcoal canister at the front ,therefore I think you are correct and I should block off all other pipes and use top one as breather . I think I will take out tank, fuel pump .lines and replace banjo connections just in case as I think the expansion tank is now a red herring .!!
Thanks again Kind rgds Alan
