Don't know what the rush is???  Be careful of your vent tube, most vent tubes are just vinyl hose and a little plastic barbed fitting with a hose clamp around it.  Mine fell off on time and it was a son of a gun to get back on because of no room to get hose clamp tight.  After that I don't put a lot of pressure when (re-filling) or better stated displacing air inside the tank with water.
I picked up one of these.

I thought is might be good for maybe 1 or 2 seasons.  That was probably 5 years ago. I'm surprised it still works for the price I paid for it.

I hooked a pump like this up to a clean sealed plastic 55 gal drum and it worked well for 3-4 years before it quit. The experiment showed me it was well worth it so I replaced the pump with similar unit that could act as a replacement pump. I can also hose into the city water supply and use the water directly from the drum.
