HWH levelling jacks fluid tank

It might be a good idea to raise all the jacks and pull in the slides (if they are hydraulic) before you add fluid. Top it off with jacks down and when they retract you will have an overflow

Tank is part of the pump. There is a vent cap on top about 1.5 inches in diameter. It unscrews to add/check fluid.

I see the pump there. the lines lead to the main control box, then off to the jacks. Still don't see a tank.

on my 96 the tank is located between the frame rails about midway of coach

My cousin had a PA but it was older and the tank was behind the rt front tire on the frame. A big pain to fill. If not there just follow the lines
