The sending unit is also from a '74 and it has the vent built into it instead of in the tank by the filler connection. Just use a longer hose from the neck vent tube to the sending unit vent. The only thing I'm not sure about is the sending unit wiring. It looks like the wire that you connect to the truck harness has a resistor in it. If when I test it before I install the last time I might have to splice a different wire W/O the resistor. I will let you know how it goes.
