One thing about "pulling water"
if you dont prime the feed line you, you start out sucking air.
This will cause damage every time you loose a prime or accidently run it dry.
I suggest that you plumb in a way to prime the feed line.
A simple y with a garden hose connector fitting will do.
i dont think you can get 8 gpm from a 18 hp engine.
Where would you pull that amount of water from?
"no need for hot water" no such thing unless you only wash wood.
Go with the hot water skid and a second cold water unit for rinseing.[cold water unit can be less pressure-more gpm]

Took all day to polish out the HF damaged windshield.
Even caustic soap's will do damage after a while.
I now use a polish called "liquid glass" on the paint and windshield.

i bought a float valve and drilled a hole in the top side of the tank as the feed.
Then i used GOOP[plumber's type from HD] and a FERNCO rubber fitting[also from HD] to attach to the outlet of the tank.
Then i made up a PVC pipe[1 1/2"] with a T to supply two wash unit's. I find the gray...
Hi APLUS< I would bet that the mix you mentioned ACQ would make one heck of a roof cleaner?
A spray on and leave type.
Quat's has been used to control alge for a long long time.

they have citric based truck wash that you can use with your 2 stepping.
It is great on house's also.
Zep as a degreeser that is a citric based cleaner and nothing cut's tar or oil better.
