Pressure washer question

[retroedaddy]

So I have a pressure washer and I want to be able to use it out at my shop. There is no water connection there and I was thinking of getting a 125 gallon water tank that I could fill and take out there. Anyone know how this works ? Would I need a pump of some sort in line to the pressure washer or does the pressure washer create enough pull ? I've seen mobile pressure washing set up's and never noticed a pump, but mine is a regular washer, designed for home use.

Should be able to just gravity feed. The pump will actually cause a little suction.

No pump needed. I do the same thing with a 120 gallon tank. Just hose from bottom side to power washer.
