Model 358.791570
The thing to remember is that the primer pulls fuel from the carb into the bulb and dumps back to the tank, it does not push fuel into the carb, connect the fuel line from the tank to the carb connection nearest to the alluminium pump cover held with a single screw, the other one goes to the shorter of the two connections on the back of the primer.

Yes, you are right. The larger line goes to the primer bulb and only goes into the tank about an inch. The coupling just keeps the line from pulling out of the tank. The smaller line goes to the carb. This line must rest comfortably on the bottom of the tank with the filter attached to the end.

Hi this is the way it should go: 1 from the filter in the tank to the bottom of the carby,2 from the top of the carby to the inlet on the primer,3 from the outlet on the primer back to the tank as this is the return line nothing goes onto it.

Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does

Fuel filter in tank with line going directly to the fuel pump side of the carburetor This is the end of the carb with a solid cover. . This line should have length in it inside the tank where it can flop around and stay on the bottom to collect fuel. The other line in the tank should have one of the little connectors on it and can be right up to where the hole in the tank is to hold it there.. This line should connect to purge/primer bulb on the longer outlet nipple. Another fuel line should run from the metering chamber side of the carb (the end with the hole in the cover) to the purge/primer bulb with the shorter outlet nipple.
The purge bulb "pulls" fresh fuel out of the tank via a vacuum created after depressing the bulb and the fresh fuel flows completely thru the carb and any air or old fuel ahead of it are drawn to the purge bulb which then "pushes" this mixture back to the fuel tank.
