Inline feed pumps

First question does anyone use 12v pumps to feed the pressure washer from the tank. Second question what size line do you use.
 
Do you think it would suck the water through if I mounted the hose up on the wall of my truck 4feet or do I have to keep it on the floor until the pressure washer
 
I have always kept my hose on the floor from where it exits the tank and have it rise right right before the pump. I wouldn't create more than one rise in your run to the pump.

4 ft high seems a little high. Not sure why you would need to do that, however, I run my water underneath the trailer and then back up to the machine. My PVC is probably about 18 inches under the pump and the water must come up that far to reach the pump.
 
Booster pumps foe tank-feed should be avoided

"up 'n over" is an accident waiting to happen..
WHEN it looses prime, the pump seals will suffer.
..same reason as these guys don't use a booster pump..
It will fail, and you still loose what you were trying to protect.

If you run 1 1/4" rigid suction hose UNDER the floor,

split it into TWO 3/4" or 1" flexible (nylon-braid) feed lines..
.. one to EACH side of the head,
and you achieve your goal..
Reliability without going across the floor.

this is 7gpm with dual 1" lines.. still on original seals, 4 years later.

Reasons for dual-feeding a pump

Whats the reason for having the supply line come in on both sides and not just the one side of the pump?<br>
<br>
the easier the pump can get water..<br>
the less cavitation it is subjected to,<br>
the longer the seals will last,<br>
the less likely you'll have cerasmics cracking,<br>
the less stress there is on the back-end,<br>
the less wear and breakage there will be on the seal retainers, <br>
the less chattering there will be on the v-belt, or especially at the crank-shafts (direct-driven),<br>
the less downtime you will have,<br>
the more reliable you can be,<br>
