Chainsaw fuel lines enter the gas tank from holes in top of tank. They are sized for a tight fit to prevent leakage. Make it easy on yourself when pushing the line through the tank by cutting a long lengthwise taper cut with razor knife 3 inches or longer to easily feed through that tight hole. Once started you will then have to grab it through the gas cap hole with needle nose pliers, then cut the tapered end flush and add fuel filter. Readjust inside length by pulling from above, then cut to length to upper carb fitting. If connecting to primer bulb a filter is not required and make sure the line goes to fitting on primer bulb marked tank.
Check the fuel lines for cracks/breaks. If they are o.k., then:
Youwill need to disassemble the carburetor and spray withcarb.cleaner.Make sure the small screen is free of debris. (Should beable to see daylight through it.)
The Smaller line goes on the Lower inlet tube on the carborater the other end goes to the gas filter inside the gas tank.
The Larger line goes on the upper outlet tube on the carborater the other end goes to a fitting that holds this tube from coming out on the gas tank .This tube is only for Air, it helps fill the primer bulb when pushed.
I hope this helps.
Mechs correct me if I have made a mistake.

it is the carburator if you take off the carburator their is two plates one on each side one is the pump and one is the inlet which has a screen the screen is probably clogged other side is the needle and seat but you will probably fine its the screen
You have/had a fuel filter in the tank.The connector goes to that filter, I think. The length does mean something but I don't know any way to figure it without a manual. You could try to figure from the total length. The fuel filter hold the line toward the bottom. Good luck.
1st get new line. find where it goes on carb. pull the line out of the tank .cut a pc. of new line longer then what you need ,cut the end of the tubing with dia.pliers at a long angle then push it into the tank untill you can fish it out hook it back to the filter pull the extra tubing back towards the carb. leaving the filter at the bottom of the tank
