pump, havent see once I placed it in, but this was some cheap garden submersible pump. Works from mains, once I connect two power leads I have a 230v inside the van, see the sockets on the first picture, one cable runs to the front and I have a switch there for the pump.
Hose reel and tank cages I welded myself.
There is 100ft of 2inch hoses and 75ft of 1.5 inch hoses. Usually use no more then 70-75ft, somethimes 100ft, more then this realy realy somethines, not recommend due to the suction.
75ft is still very good, 100ft is very acceptable but if more you start feeling the lack of power, but still prefer more hoses, lower pressure and work a bit slower then remove the machine and work with buckets.
