Put a filter under the truck inside the frame rail, before the fuel pump. And gas it and go. And if the carb has a built in filter thats even better. Think about all the fuel injection systems in the newer vehicles. All the filters are before the fuel pump, and nothing before the injectors (as far as I know of anyway)

The steel line GM used for the fuel line on our trucks has a double flare end just like the brake lines do ( I attached a photo for example). The fuel line is just a larger size at 5/16" They used this all the way up to 1987 when they started with TBI.

Also most factory style fuel injection fuel pumps are in the tank and have an external fuel filter somewhere under the car in line so it can be serviced. It is best for a carberated vehicle to have a filter after the pump in case the pump fails, there is a filter to catch the debris from the failed fuel pump. The in carb filter on a Quadrajet is more than sufficient to filter the fuel.
