LSFM Tanker won' fill sprayer (FS19)

[dogwalker1]

Pretty much what the title says. Bought the LSFM Innovations UTT 7500 tanker (from the popular Universal Tank Pack) , filled it with liquid fertilizer, then tried to fill my stock game sprayer from it. Ensured the correct implement is selected (G). Tried it first with the sprayer attached to the tractor, then tried pulling the tank itself up to the sprayer with the tractor. Tried from all possible positions & angles. No luck either way, the trigger never appears, not the [R] option. What gives? Ty.

Ah nm, found it in an old post. Need to buy a hose, attach it to the tanker and sprayer, open the tanker valve, set the pump to correct flow direction, then with the sprayer attached to a running tractor press 'R' to finally fill it.
