richie rich Posted July 26, 2014 Share Posted July 26, 2014 Hi my km motor fuel cap leaks unless I tighten it that much I can barely undo it again is it worth getting a standard hpi one are they any better or will a alloy one be best ?

atom3624 Posted July 26, 2014 Share Posted July 26, 2014 Check that you haven't cross threaded it. Is it an alloy cap? Al. Quote Link to comment Share on other sites More sharing options...
MattyDunkley Posted July 26, 2014 Share Posted July 26, 2014 both mine and my mates Km done this but we fitted o'rings on the inside lip of them cap and they dont leak anymore not sure how long the o'rings will last with petrol though ? :/ Quote Link to comment Share on other sites More sharing options...
goldman Posted July 26, 2014 Share Posted July 26, 2014 I had same thing on a Punisher,so made a gasket for it,worked for a fair while,Some Orings are ok with petrol, so should work well,and even if they don't last,spose cheap to have a few spare.
