My first choice is to use a vehicle with multi port fuel injection but I do understand that one must use what they have in most cases . Personally the only trucks I will gasifie will be multi port. They operate so smooth and nice with the computer and very little maintenance .
With that said I have had 3 trucks with carbs over the years and have put down thousands of miles with them . Two of the trucks I piped the gas under the carb to a mixing box or plenum . On these two trucks I use two throttles and hybird very easy if needed.
The last truck I used with a carb was a 85 , 250 ford with a 460 motor. On this truck I ran the wood gas into the air filter housing just as I do now on the later model trucks . This is a much simpler build than the under carb plenum but any hybrid driving doesn’t work out very well. It is gasoline or wood.
I bypassed the mechanical fuel pump and installed a small inline electric fuel pump that I could operate from the driver seat.
Below is a short video of switching the truck back and forth from wood to gasoline .
Also a short video of working the ole truck .
