Poulan 2050 chainsaw. Fuel line routing: Replaced all fuel lines which had rotted away. Primer bulb is marked tank and carb side. Tank side is for larger line and runs into tank. Is this the "vent line" that only sticks in about 1 "?. Carb side is smaller diameter line and runs to carb but which fitting? Remaining carb nipple with small line runs to tank and I guess the fuel filter? Cannot find specific info anywhere. I had the fuel filter on the larger line in the tank but that does not work as air is pushed OUT of filter that way. Thanks. Rick
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!
