Ryobi Grass Scorpion Petrol lines from tank to primer to carby where to where

The petrol lines on my Grass Scorpion have aged (12 years) and broken. I need to know the circuitry from Fuel Tank to Primer to Carby. TWO lines go from Fuel Tank, NO.1 from Internal Fuel Filter in Tank to ??? and No.2 from Fuel Tank to ???
These lines obviously go to the Primer Pump and the Carby. But which goes to which???"
The replacement of all these fuel lines is quite simple but I cannot find anywhere a Fuel Flow Circuit Diagram.
The Ryobi Grass Scorp[ion has worked perfectly for 12 years and I am loathe to put it to rest. It has become a member of the family

    You have just saved me over A$100. My wife said "After 12 years good service, just buy a new one".
    The Ryobi is just as good a workmate as our two border collies are.I just couldn't take it to the tip.
    Two years ago I had two stents put into my heart so I know how the old Ryobi feels.
    Thanks for your help.

Thanks to

The line off the top of the primer bulb goes to the top of the carburetor.
The line on the bottom of the primer bulb goes to the fitting on the center of the fuel tank and the line off the side of the fuel tank goes to the bottom of the carburetor.

    your outlet from feul tank goes to primer inlet (shorter one)
    and other hose one end should be connected to the free end of primer(longer one ) and the other end to the spigot (brass color one) on top of carby and the other one end connecte to 
    spigot at the buttom of carby and other end goes to fuel tank

Bought it at local, start alright with petrol. When try with 2 Stroke RYOBI Synthetic Oil hard to start. Should i just use normal petrol oil?

no --- 2 strokes use a special 2 stroke oil ==not ordinary engine oil==
the difference is that the 2 stroke oil is specially blended to mix with petrol and will not block up the fine jets in the carby
it also "sticks " more readily to the metal components in the engine thus preventing wear
as a point of interest most small engines do not like E mix fuels either
so for trouble free operation --2 stroke oil mixed in the correct ratio with either 89 or 91 octane petrol and it will start first pull every time
use the primer bulb sparingly or the choke until it fores

Ryobi Weed Wasp starts but cuts out after 2 to 3 seconds.

Sounds like it is running on the prime. Check the fuel filter in the tank and if it looks clogged or dark, replace it. If that is not it, now is the time to consider a carburetor clean and rebuild, with a replacement of fuel lines and primer bulb. Today's ethenol in gas is murder on small engine soft components.

Ryobi line cutter - petrol lines all broken

Petrol lines disintegrate when fuel is stored in the trimmer for long periods of time. These can be obtained from any small tool repair store. Just remove them and install new ones. They just slip through the holes in the tank, re-attach the fuel filter on the supply line. Make sure that the line is long enough so that the filter rests on the back/bottom corner of the tank. Be sure that the lines are attached to the proper ports on the carb>
