Jim, the basic answer is yes. Ideally you can use a plastic straw on the end of an aerosol can of carburetor cleaner to start the initial dissolving of the dried gasoline. I am assuming you are using an electric pump, but however you can mix some Seafoam in about a 50/50 mixture and get it into the carb. bowl, it will likely start working on the accelerator pump circuit too.

Once you have it cleaned, find a small municipal airport where you can purchase some 100LL fuel for your boat in a jug, and then install that into your truck's fuel tank away from the airport. The AV gas does not sour or taint like ethanol fuels do, so this should keep the passageways open during stowage. Around here, we are paying about $5.30 a gallon for the AV gas, but it is a much better solution IMO.
