I picked up a used craftsman model 358350370 and discovered that the fuel line is broken up. I can see that a line goes to the priming bulb, and one comes from the priming bulb and there are two connections on the carb, but I do not see how the line exits the fuel tank through the hole in the side of the bottom and where it goes. I have three lines which must connect in five places excluding the filter, and only find four connecting points. Help!

Fuel lines probably need replacing. Have you been using ethanol? The alcohol eats the fuel lines on most 2 cycle motors up.

The second line you are asking about is a pressure line that just goes inside the take and when you prime the bulb it puts pressure in the tank it is not attached to anything in the tank only to the primer bulb.

hello sir,routing fuel line for craftsman,homelite,ryobi,hedge and line trimmers,fuel tank under engine, looking at machine from rear, shall fuel line on left with filter attached goes to bottom port of carb, fuel line from right side coming out of tank with inside tip attached goes to bottom port of primmer bulb,top line on primmer bulb goes to top port of carb, fuel tank under engine,fuel line routing,looking at machine from left side, left fuel line coming out of tank(drain back only) goes to right side small port of primmer bulb, left side larger fuel line from primmer bulb to top port of carb, fuel line coming out of tank (larger line) on the right side with filter attached goes to bottom port of carb, when replacing fuel line it is very important to use the same ID and OD line the homelite takes a special line that is black in color and a bigger size,the bigger line is ID .08-OD140 small line ID3/32 X 3/16.when the lines dissolve small pieces will get in the carb clogging small passages and screen,it is advisable that you clean out carb,and use a new filter.hope this helps,any comments welcome,thank you. if the filter has broken off of the line half way that is where you will run out of fuel, hh

Make sure the line is near the botto ofthe tank.Thanks you for asking and I hope it helps.Please leave me a 4 thumbs up.

The smaller diameter line (fuel supply) goes from the fuel tank (w/filter) to the carb body. Look carefully at the 2 nipples on the carb. You can tell one is slightly larger than the other. Another larger line (purge line) goes from carb body to the right nipple on the primer bulb. Another large line (return line) goes from the left nipple of the primer bulb into the fuel tank. completing the purge circuit. This info pertains to the Craftsman 32cc with Zama carb and may work on the 25cc model as well.

the inlet line has the filter on the end in the tank
that goes to the bottom nlet of the carby
the return line goes from under the primer bulb back to the tank
some units run a 3rd line with a filter on the end ( outside of the tank0as that is used to vent the fuel tank as the cap is sealed
the fuel flow is this
through the carby through the pump back to the tank and is only used to prime the float bowl ( needle and seat and diaphragm with fresh fuel and to remove any air in that chamber

1) Check fuel lines from tank for cracks, fuel filter in tank, primer bulb for cracks

2)Remove Carburetor
replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

A new carburetor would be simplest solution. You could try disassembling the carb, cleaning and replacing diaphrams, but just replacing the carb would be my choice. What is the model # on the trimmer and I can tell you the part # of the carb you need.
