Hey everybody. Living in Phoenix, I've been dealing with vapor lock on my 60 for a long time. I've taken a few measures to improve it - an electric in-line pump mounted low, shielding the hard line up by the head/manifold... But still have the occasional issue when I drive it on hot days. I understand an in-tank pump is the best solution, but one thing I haven't been able to find is anyone trying is a check valve. Putting a check valve just downstream of the pump should prevent the vaporized fuel from pushing the cooler fuel back past the pump... Right? It seems like a sure and easy solution, but then why hasn't anyone done it? I feel like I'm overlooking something. The valve would keep the pump fuel wetted and force the vaporized gas into the carburetor, which shouldn't be a problem, right? I'm not familiar with the fuel circuit... I don't believe there's any bypass back to the tank. Has anyone tried? I bought some good fuel-safe valves and might just do it unless someone foresees an issue. Thanks!
