Hi there, I am having an issue with my petrol tank cap leaking fuel through the keyhole. I have changed the o ring on the one way valve and also the main cap gasket but it still leaks through the key hole. I think the one way valve may be damaged.
Has anybody got a 1 way valve or petrol tank cap that they could let me have?
Kind regards
Fry
PS the picture shows the valve
PM me your details and I will dig one out for you
I think mine has started doing the same thing so if you do find out the cause (even if it’s “Fuel cap change solved it”), I would really appreciate hearing from you. Thanks.
Hi Gareth, there are a number of solutions on here for leaking fuel caps and quite a few folks have solved the issue. I have tried both the fixes and mine still leaks…lucky me!
The fixes are:- changing the main rubber seal if fuel leaks out the cap and changing the one way valve O ring if fuel leaks out the key hole. Both these fixes can be found with a search on this excellent forum.
Hope this helps
Thanks for the advice buddy. It seems to be coming out of the key hole so will try the O ring solution first.
