Im having air suspension problems on my ford 1999 expedition.

(1999 Ford Expedition)
Im having air suspension problems on my 1999 Ford expedition v8 engine. I've tested all the lines and bags for leakes with out problems. Replaced a rear height sensor. Checked the front height sensor works fine. The pump turns on and off no problem. The relay under the right fender is fine and the pigtails are good as well. I'm unsure why the bags aren't getting air it's driving me crazy.
What seems to make the problem better or worse? Nothing
How long have you had this problem? 6 months

The pump may sound like it's working but is not actually creating any air pressure. Try taking the feed line off, activating the pump and testing for air flow

So disconnect the air dryer from the pump and feel for air flow?

Should I disconnect the hose lines from the drier and feel for air or remove the drier and feel air from the pumps unit?

(Update) I removed the drier from the pump and felt air moving when the pump was on but i don’t know how strong the air is supposed to feel when it’s pumping. It wasn’t strong but it wasn’t weak either.
