Just got home from xmas in the city the last 5days.. went to a large general tool/automotive store this morning (Princess Auto), got lost in there for about 3hrs    and I found this nifty little bilge pump   .. suppose to be capable of putting out 170 -200 gph meant for boats & what not, runs on 12v.
  
Outlet is 7mm id -> taper it down to 3 or 4mm should produce pretty good press for either a nozzle or spray bar the width of trk. Put it on an esc to vary the voltage, which will vary the press & flow. It can be totally submerge, so I'll just put it right in the tank! Start building my water hauler here shortly for the floor dig.

 Joe    You have that water hauler built yet ?   Time to post some photo's..
Happy New Year !
