Mr. Sam...might be a silly question, but is that pump hard to prime as far as it is from the water to the pump? Do you have a bypass from suction to the flow line on it to fill it with? Or do you have to haul water from river to fill it? I worked a number of years in the oilfield and used a number of different types of pumps and sometimes they could be a booger to prime. So, when I see something like that, I had to ask. It just looks like with the large of a suction and that long from pump to water it could be troublesome?
