Difficulty in priming / using booster pump

check the hose clamps. They don't always stay fully tightened. It may be your banjo valve. You want to keep a couple extra on hand anyways so just swap it out and see what happens. I think I get mine from Zoro tools.

It could be the check valve in the tank as well.

Is there a multi-tap on that? Check to see if when the valve is closed, it is drawing air through the multi-tap.

I have tightened all the hose clamps. Don't see any leaks there.

I did not know that there is a check valve inside the tank. That will be difficult to tackle!!

And no multi tap on this pump setup.

I think I will change the banjo valve, if the check valve proves to be ok

You may want to reach inside the tank and make sure the tube going down into the fluid has not backed out or vibrated loose causing you to suck air at the connection point at the top of the tank.
