The fuel lines connect the tank(2) primer(2) and carburetor(2) What goes where?

Huh?

huh?
Which line from the tank goes to which primer connection? Which line from the tank goes to which carburetor connection? Which line from the primer goes to which carburetor connection?

Which line from the tank goes to which primer connection? Which line from the tank goes to which carburetor connection? Which line from the primer goes to which carburetor connection?

The line from the filter goes to the longest nipple on the primer. Then it would be hard to say without actually seeing the unit. If there is a connection on the top, or front, edge of the carb. Put the line from the primer to this one. And the connection on the bottom, or back, side of the carb to the tank.

How do I replace the small fuel line on a weed eater #GTI 19T. Current line has spli and leaks fuel.
Thanks, Fred

Tricky tricky. Factory uses a small pulling tool. I get 2 ft of fuel line $3-4. Slit the line so the thin sliver can be fed into the tank and out the filler. Stretch the line and pull it into the tank, trimming it off so the filter is always in fuel, connect other line to suction side of primer. Do the same again with return and just make it long enough to go into the tank, plus 1/2 inch. Trim other end and connect to carb. Some of the older units have 3 lines!!
