Stuartanders1968 Posted August 18, 2017 Report Share Posted August 18, 2017 I have a 1980 Spitfire 1500, with a terrible smell of fuel in the boot, there are no leaks from the tank, but I have noticed that the vent tube on the top now only has a clip and no hose, should it be sealed or vented, if vented which is the best & safest way to do this?

Pete Lewis Posted August 19, 2017 Report Share Posted August 19, 2017 I think if the caps seal is vented and has small hole in the vent tube is capped . otherwise its a tube down through a hole in the boot floor can be bundy or nylon tube its an idea to put a coil in the pipe route 1 Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted August 19, 2017 Report Share Posted August 19, 2017 This might help-.Mine is a Mk1V which is probably similar . It has a vented cap and the tank vent diidn't go anywhere. It was blanked off with a rubber cap held in place by a clip. The cap had perished/ disintegrated - suspect yours has and the bits disappeared resulting in fumes venting into boot. Assuming the cap is vented, then the answer is to close this tank connector off again - various approaches - renew the rubber cap (but it will gradually deteriorate again) , a short piece of petrol pipe with bolt to occlude etc. I opted for closing it off with a brass stop-end - 8 mm central heating (from the usual diy or plumbing supplier) which fits in seconds and provides a more permanent solution. 1 Link to comment Share on other sites More sharing options...
