Where does the gas go? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi Everybody,
I have a 86 CC, 1-ton with a 454 that after setting for a few days, needs to be cranked over quite (40 sec.) awhile before gas will get up into the carb so it will start.
Does the fuel system have a check valve that keeps the gas from siphoning back to the fuel tank? This did the same thing with another carb so I know it's not that. The engine doesn't run hot so I don't think it's boiling off. Where does it go??

Thanks everybody.......John
