Last nite out of the blue, primer bulb would not prime motor. Have about 3/4 tank of gas. Today I put a new bulb on and same thing. Disconnected line and hooked to another tank and nothing. If I disconnect line from motor...bulb will get semi hard....and when I press in on the quick disconnect...it will spray fuel. Only when connected to motor...it will do nothing. Usually 2 or 3 pumps to fill fuel filter....but now it will not even push anything up to it. All line is new. Can the quick connect on the motor go bad?....or the one on the line?
