    Typical mechanics ripping people off.. The supply line comes from tank n goes to davco filter first n there is no return line to davco..so only way for air to get to davco is from tank when air is returned to tank from bad cups But that's not gunna happen because in tank return line is higher that pickup line n air is going to immediately rise to top of fuel level there for can never make it to pickup tube.

    I was seriously asking. Perhaps they loosen something up or something. Once Caught a heater guy doing something similar to a gas line.
