Add on to my UTV Overall I am satisfied with the 25 gallon tank and sprayer. I found that on hills or inclines it's best to keep the tank full at that point...otherwise the vacuum was not operating correctly and the fluid was delivered intermittently. After leveling out it continued so I opened the filter housing for relief. It seemed to correct itself so I followed those steps each time it occurred. I wish the hose was a bit longer but adequate for my needs. The website shows a link to the 25K manual but if you click on it you are taken to different product. As far as a power source I deployed an external 12 volt deep cell battery (listed below) It worked well with the provided parts that are packaged with the pump (alligator clips and cabling). https://www.batteriesplus.com/productdetails/sladc12=35j I would recommend a 12 volt trickle charger for the battery as well. For my needs I ran the tank for two times, totaling 50 gallons. The battery was at about 65% capacity so I would assume I could run out about 125-150 gallons before recharging. Tioga county, Pa.
