Pump doesn't shut off

So, I finally fixed all the leaks in my 72 tradewind. But, my pump never fully shuts off when all the valves are closed indicating that I have a leak somewhere. I let the pump run for 30 min or so and no leaks or running water of any kind. When standing above the tank area if I put my head close to the floor I can hear a faint bubbling sound. But, no leaks or running water. I have the old fresh water refill. Could it be sucking air through this and not allowing the system to pressurize? Any help would be great. Thanks.

Are you sure the pump is good? How about the seal around the pump inlet? Could it be sucking air? How's the water pressure in the lines? Good or weak?

Did you open all the faucets for a few seconds to let the air escape ?

No faucets are installed yet just shutoff valves. The pressure is good. Not great but good. However when I open both hot and cold valves in the bathroom the hot line is a dribble and the cold line runs good. What's the pressure suppose to be?

can you stick a temp line on the shutoff valves and let the air escape ?

I've let the lines empty into a bucket and closed them under water to ensure the air is escaped.

If there is no air coming through the lines then the pump is suspect. It could be leaking back through the check valve.

Pump doesn't shut off

That was going to be my next fix. I don't know how long the pump has been there. I bought the trailer in the high desert in CA with the door and the back window removed. So the WHOLE thing had roughly 1/8" of dirt inside. Amongst other adult "goodies". Lol. So gross!!
