I have a direct drive unit (3800 psi, 4 gpm) that I want to use mobile for some side work. The owners manual has in big bold print that it must have 5GPM at at least 20PSI.
Should I not even bother with trying to draw water from the tank and go right with a positive pressure setup like a Flojet On-Demand Pump 4.9 GPM, 12 Volt, 3/4in., Model# 04300143A | 12 Volt Pumps | Northern Tool + Equipment
I have searched on this topic and it seems to go both ways.
