Two alternatives that comes to mind: 1/ Buy an inverter and a 110V

This is going to be really stoopid, but hey it's Friday:  how 'bout using
the engine as a pump???  I'm imagining removing all plugs, ground the coil
wire, disconnect the fuel pump, then screw in a long hose with a compression
test fitting at one end & a tire filling valve at the other.  It shouldn't
take but a couple of seconds of cranking to fill up a tire  ( & it's at
least 130 psi - could do road bike tires too!!!)  ???.   Comments  (be kind
- it's been a long week).
