7 gpm fat boy 12 volt pump

Just gonna throw this out there; a 12v suffers from every restriction and bend. The proportioning valves and the 90, the hose barbs down to 1/2" on the supply side, etc.

Feeding with a smaller ID than your output isn’t doing you any favors. My 7gpm 12v has a 3/4" hose feeding it: no 90s, no proportion valves, and 200’ of 1/2" hose into a pvc j-rod setup. I can just about shoot an arc over a 2-story

If your water line don’t have a metering valve on it, you won’t get accurate % of mix coming out. That’s if you’re using a ball valve for water. The metered valves are more restricted than the ball valve. You won’t be able to run ball valve wide open, will need to be tweaked a bit.

There’s some good info here and I agree that you really only need 1/2" for that pump. One question that I don’t think has been asked yet is did you pull all the hose off the reel for your test? You need all the hose stretched out so it can flow it’s best.

Yes sir I did pull all the hose off the reel… I will make some adjustments and see what happens…

I’m going to try what you said… I will keep my metering set up just downsize to 1/2 inch hose and upsize my feed lines

It should help. At least it’s better than the other way around. You never want that pump to starve

It’s your gun. Use a ball valve reduced to 1/4" and use 2560, 0060 tips. M5 twist is for soft washing with a pressure washer not a 12volt

Also, stay with 5/8" hose

Get rid of the sutner and twist, those are for soft washing with a pressure washer. Use ONLY a ball valve (sch 80 preferred) reduced down to 1/4" and get a jrod with xx60 or xx50 (xx = 0, 5, 25, of whatever you prefer). Once you find the tips you like, DONT change them otherwise you will always doubt yourself. Too many times have I had things perfect later to find myself watching a YouTube video and then doing a complete remodel of my once perfect set up. Find what works best for you and go make money! PS - Stay with 5/8" hose, anytime you can have more flow at the spray tip you will do Great. Just like pump supply lines, Hose diameter should be double the inlet which prevents cavatation and starvation. You want your supply to be heavily ready at all times.

Thank you for the great information…

Does this mean you run 1/2" or 3/4" pressure washing hose?

I watched your video on the nozzels you use, but I never got the name of this one in the picture.

How come nobody suggested to use the shooter tip? My Jrod has the long assassin shooter tip and that works great for me.

@Racer It’s a fancy nozzle you got there Racer. Where did you get it?
