I have been given 3 Robart Super Pumpers # 209 (they are black with set screw for flow adjustment) they each have 4 hose barbs,,

can anyone give me info on them, are they still being made, how well do they work ??,,

they are for gasoline, but can they be used for glow fuel ???????


I have a 3rd one that is all metal (sliver), with NO adjustment and only 3 hose barbs, it's manual doesn't say if it's for gas or glow, can I get more info one this one too please..

thanks !!
Jim
