Another quick question or two: I have a 6 H.P. Evinrude, 1991, model E6REIA. It has a 3/8" fuel line. No in line filter under the cowl other than the fuel pump screen. I have a glass in line filter I am thinking about installing on the fuel line outside of the motor cowl First of all, should i put an in line filter in the line and secondly if so, should I install it between the tank and primer ball, or between the primer ball and motor? Thank again guys!
