I have received the 42ltr auxiliary tank and prefitted that in the same location as original. The Monte Carlo cars had twin tanks with a total of 102ltrs of fuel capacity and an electric Stewart Warner fuel pump to transfer fuel from the auxiliary tank to the main tank. the standard Ford mechanical fuel pump was used to feed the carbs.
This tank will be used as the fuel cell after some mods
Below was the set up on the 1963 Falcons, The 64s were a little different but still twin tank
