For a test I've just got myself an atv 55 litre spot sprayer from quad bike wales to throw in the van to try out with some small benz blackwash jobbies instead of trying to run it through a standard shurflo wfp pump. Not sure how long that 60 psi 8 lpm pump will last using a weak hypo based softwash mix though but was cheap as chips so I'm not realy that bothered.
The pump that came with the tank was the following spec.
