The thing on my air compressor with a +/- knob and a pressure gauge is leaking. Its a POS Meijer Shop Force 6 gallon compressor. I got it for $60, cant beat the price. Well in less than one year, the regulator part is leaking. Sears has this part for about $24. Cant see spending that much on a $60 compressor. Is there any other place to get this part (quality part hopefully) for less? Menards, lowes, online?
