Hi all, please help, ive got a strange fuel leak, i fill my nova, maybe 10 or 20 pound, its a project ive had for about 2 years now, so it mainly sits in the garage, after i put the fuel in start her a few times on weekend maybe, leave till weekend after or few weeks shes nearly empty!? I cant see no obvious fuel leaking from anywhere, no patches on the floor, has anyone got any ideas, i might try changing the filler cap, thanks all in advance
