Poulan 2050 fuel line routing?

HELLO make sure u have 2 different (OD) diameter FUEL lines. The smaller one (thinner line) attaches to TOP NIB of carb and has the FUEL filter attached to it. The LARGER diameter fuel line goes to the bottom (of carb nib)=return line..this also goes into tank down about 4-5 inches.
ON the back of the PRIMER bulb in small letters is MARKED TANK and another marking names CARb..that is where you hook up the lines there....a LARGER size fuel line will suck up air and NOT work if u attach a filter to it. ..the line muct be a SMALLER diameter that goes to TOP of carb nib and into tank with filter attached.
GOOD LUCK!
