Hi all, new member here.
I have a 1977 sovereign 3.4.
having issues with the anti run on valve. I was driving on a 370 mile trip and fuel started leaking from the valve, I am sure this should not have fuel going to or from it, I have purchased a new valve (America) I was wondering if they could be an issue with my carburettors ?
Thanks all

 

Does your car have a charcoal canister? Look for raw fuel there too, symptomatic of changeover or return valve sticking or leaking which is symptomatic of rusty fuel tanks and leads to fuel in the venting system. Smell raw fuel near the C pillars etc... Can be a real fire hazard.
