Leven petrol cap problems
Discussion
Just treated myself to a nice new shiny petrol cap, however, since fitting i have noticed a lot of banging/popping from fuel tank. On inspection the old cap has a sprung cone section(assuming pressure relief) and a section of the cork seal missing. I'm pretty sure my purge filter thingy is not working properly and cannot afford to fix this at the moment. Is this dangerous? The new Leven cap does not have a relief as far as i can tell and removing the seal means it will not fit properly. Anybody else had this problem, if so what did you do to correct this(apart from replacing it with the old one).
Many thanks in advance

I am pretty sure, i gave her the spec and she was happy it was the right one (1995). It does fit well with the seal. Does the other have a relief system?
I'd give leven a ring in the morning ive got one secondhand and it's a flat base and had problems as well fitted the old one back on.I assume i had bought the later cap.
There's 2 types just listed on ebay so should sell for more than leven's retail price
, why was'nt that there yesterday!!!
I fitted a Leven one and no problems so far. I am not sure the sprung cork in the original is designed as a pressure relief because tightening the cap on removes any movement of the spring. In any case tank tends to form a vacuum anyway so that just pulls it on tighter.
Maybe your carbon can needs replacing?

If it fits you've bought the right one. I think the problem is the new cap is sealing too well and so you're creating a vaccum as the petrol is drawn from the tank.
I think the mod suggested by Leven is to drill a small hole in the neck of the filler cap or remove a little of the cork gasket to allow some air into the tank.

I think i'll take a slice out the rubber gasket and try that. will post back results just for future info but maybe a while as car is going in for new seats/carpets/hood this weekend....
(sod the rusty outriggers, knackered diff, whining gearbox, saggy suspension, exhaust manifolds etc....it'll look nice!!)

I'm filling her up every other day and seeing some crap looking cap when I open the boot. I'd like to see something shiny 
I am hoping the Leven cap would provide a more pleasurable experience when taking it off/putting it back on again that the rusty, nasty screw top bottle thing that doesn't really allow a good grip on it without clamping it like a vice, and have a definite point where it binds on the thread, too.If the Leven cap sorts that in addition to providing a quality finish to the under-bootlid 'glass I reckon it's £45 well spent (especially at the current £ exchange rate

As well as letting air in,doesn't this let the petrol vapour fill the boot area/car and make the car smell of petrol?

I would have thought so. AFAIK it's not designed to be a vented cap: if the carbon cannister and purge valve are working properly you shouldn't need to introduce a makeshift vent."I think the mod suggested by Leven is to drill a small hole in the neck of the filler cap or remove a little of the cork gasket to allow some air into the tank."
