I have a landscaping customer that is putting in an above ground self contained gasoline pump with a 500 gallon tank, does this meet all the requirements of 514? The manufacturer said most people just run an SO cord to the control box. That doesn’t seem adequate to meet and definitely doesn’t comply with 514. The tank will be about 100’ from building/panelboard feed. So I have to trench and install underground conduit to feed this. Any help is appreciated.
