Hello Road Warrior,
I bought a pump from Tractor Supply only to return as defective.
I ordered one from Harbor Freight for half that is amazing. Only 2" but will pump uphill a little over 400' and fills my 21x41 pool w/ less than 2 gallons of gas. 2 years with no problems and starts first or second pull. $189.99 item # 69774.
Do not but there hoses as they are junk. I did buy mine at Northern and local Tractor Supply.
One thing you have to drain and lube each winter. Mine has been outside and weekly use all this summer.
Good luck.
