You didn't mention. So I'll just throw it in;
If your tank isn't emptied, that is, if you don't empty the water accumulation in the tank. It will limit the tanks (air) capacity, which also effects the run time for the pump -- seems to run constantly.
But in the end, even if you
do find that there is a lot of water in the tank. It looks that if your wallet will support it, it's probably in your best interest to simply get a good (better) replacement pump for your tank.
Harbor Freight often has decent pumps on sale for a good price, and most of them offer a lifetime warranty -- and made in the US of A.
