I am curious to know what types of pumps are in use to pump liquid feed.  
I use a 4.9 GPM Sur-flow 12 volt pump to pump sugar solution through a 100 
foot hose.  I run the pump off a marine battery independent of the truck 
and have an inline filter (T-Jet) placed in front of the pump intake to 
pick up any particulates.  The hose is mounted on a hose reel and I use a 
200 gallon 'tote' for the liquid feed.  I use an aluminum gas nozzle to 
dispense the feed.  This set-up works pretty well but my pump is nearing 
the end of its useful life and I would like to go with a higher volume 12 
volt pump.  The only problem I have with this set-up is purging air from 
the line from the tank to the pump when the tank gets low and the sugar 
solution sloshes around.  I installed a 'T' with a cut off valve on the T 
that allows me to purge the air, so that solves the problem most of the 
time.  Does anyone have suggestions on higher volume 12 volt pumps?
 
thanks,
