My Rioby trimmer ned fuel hoses change how i do?

Typical fuel line routing is:

One line (the one with the fuel filter in the end of it) comes out of the fuel tank and goes to the bottom fitting on the carburator. The second line comes out of the tank and goes to the bottom fitting on the primer bulb. The third section of line goes from the top fitting on primer bulb to top fitting on the carburator. Hope this helped and best wishes.

Take one part of the hose off and have it matched. also buy a small tube of dielectric grease.this is sometimes called tune up grease.replace hoses one at a time. when you get to the fuel tank you will probably find the hose just disapears into it for this next part you will need a piece of wire and needle nosed pliers. empty the tank and fish around for the line grab it with the pliers and pull it through the filler. cut the other end off where it enters the tank and remove.remove the filter from the old line and cln w/carb clnr. take the new line and make an angled cut on the end then grese the inlet hole and the fist section of lie and work in. when you have enough line in the tank that you can see it and pull it through the fiiler do so and cut the line off flush and reinstal the filter.stuff all back into tank and pull about one inch from the other side.then cut off excess being sure to allow enough to hook back up
