I recently made some modifications to the pure water delivery system I have installed into the back of my toyota tacoma work truck. Basically all I did was create a board that holds two shurflo pumps which are plumbed and powered into my single operator wfp system. With the use of a few shutoffs i am able to pick which pump draws from the water tank. The reason for this is because i did a large job a few weeks ago and my only pump failed me in the middle of the job. The ida was that this setup would allow me to switch to my other pump and be up running again within a minute or so.
The first pump (left) works fine however the second pump (right) is not able to draw the water out of my tank and into itself to push it through the rest of the system
I am not sure if this is a matter of the pump needing to be primed or what. Any help is greatly appreciated!!

Side note** I see most wfp systems go tank>pump>filters>hose reel>wfp then on the window.
Would there be a noticeable difference on the pump as far as strain/life expectancy if i were to set my system up so the filters and DI tank were all before my tank meaning i would use the garden house pressure to put water through my filters and fill the tank then simply use the pump to transfer pure water from my tank to hose reel?
Thank you in advance!
