Have had this little motor for 30 yrs. Runs fine with the Sears tank with the little bulb pump and tiny hose. You can still but these tahks. Problem is i am tired of buying them. Have bought $200 in tanks for a motor that is progbably now worth $100. These things just seem to discentegrate in this 100 degree TX heat. I tried using a big tank once but the bulb seemed to suck shut or something so had to go back to little tank. Does anyone know if these motors will run on any kind of good metal tank assembly? Sure thanks for any help. dlange
