I have been making a lot of mods and I just don’t think the pump gauge is cutting it unless I take a real long drive and get the same pump. The less expensive boat fuel meters seem to be discontinued and I can’t justify buying on of the $400 versions. Thanks for your help!

1966 model would have virtually no inspection restrictions, at least here in Virginia.
You might consider using a burette and a t connection into you existing fuel line at the point where the rubber hose connects the metal supply line to the fuel pump (assuming it is mechanical). You would also need a means to disconnect the main fuel supply and switch to the burette (mechanical cable to a switching valve).
This would give you very precise measurement of fuel delivered to the engine, but in a limited quantity depending on the volume of the burette. You would cap the burette with a vent fitting that was directed to outside air, or just place the burette outside of the passenger compartment in one of several places. The burette should be of a plastic type, not glass, and be impervious to your fuel, with no open top that could spill the fuel.
