First of all we have a dash 6 an fuel line (3/8"). we disconnect at the carb and use a length of dash 6 and a union and run the fuel into a 5 gallon container
we also pull the fuse in the panel for the coil(ignition) so only the pump runs,we have done this several times to set the fuel guage at empty(which is programable) and we should have said we have a Painless fuse panel with everthing on its own circut.
