Cleaning out a used Suzuki tank and it has the "universal" hose connection" attached, can I remove and turn-in a Evinrude /Johnson connection for use? OR make an intermediate hose for the Evinrude /johnson hose?? Also, tried rinsing out tan with gas and filtering through four coffee filters, I thinking of letting everything evaporate and then swilling with lot soapy water and flush with hose and let evaporate of asphalt drive. What you you think??
