Physically Impossible

The facet style pusher pump can pump right through the mechanical pumps, and the mechanicals can pull right through the facet pumps. Once you try the $10 (ebay) facet style pump you wont understand why you kept pumping the carb (and killing the starter) for so long. flip it on, wait 5 seconds and its full. Wire it to the ignition switch so you dont even need to turn it on manually. Those facet pumps can support a 440 , all the motorhomes had them . IIRC someone told me a 70's Mopar had this same setup: Motorhome chassis, Hemi Dart?
This kind.
