Plumbing two units that im running "Siamese"

Hey yall, I’ve got a newbie question for you.

I have 2 4 gpm 4000 psi direct drive pressure washers. On my trailer is a 330 gal ibc water tote. Off of the ball valve is a 2 inch 90 degree reduced down to a garden hose fitting.

I am looking for advice on how to plumb both units which I will be running at the same time from that one water tote. I have tried to gravity feed them with no success. My intent is to feed each unit with 2 5.5 gpm water pumps. With that said, how would you guys plumb this? Can I go from the ibc tote ball valve into a Y then use suction line from there? Tia for any help you can offer!

I’d probably go: 2” ball valve → 2” Y or T → reduce to 1” non-collapsible → mesh filter → 5.5 pumps → 4 gpm machine.
