Check valve?

[donm]

To start my car when it's been sitting for a few days, I have to turn on the ignition and wait 10 seconds for the tank mounted electric fuel pump to deliver before I turn the key to start. I'm thinking placing a check valve in the line would fix this. Anyone else done this? What kind did you use and where did you get it?

Almost any decent auto parts store will have a "universal" fuel check valve that you can put inline; you just need to find one that fits your fuel line size. However, I'd try to find a well built metal one rather than the cheapo plastic ones that may or may not seal 100%.

A thought: Fuel shouldn't be evaporating out of the carb float bowl within several days. A week or two, perhaps. Of course, if your car sits in direct sunlight in the heat, that might speed things up. Is there a chance that the carburetor float cover is open to the atmosphere when it shouldn't be?

That's a thought but if the float cover was open as you say wouldn't it be obvious? Or is there something I could check within the carb? (32/36 Weber)
