Gas lines on ryobi cultivator 410aa fell off. replaced lines, tank, and the bulb. will not crank. need info on where line go

you will have 2 lines at the tank. 1 is the supply line with one end having the fuel filter on it and sitting at the bottom of the tank. it generally runs to the inlet side of the carb. the output side of the carb usually goes to the primer bulb inlet, the last hose usually goes from the outlet of the primer bulb back to the fuel tank but only goes in 1/8 to 1/4 of an inch. it should only be in far enough to seal the hole and allow the fuel back in to the tank

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, ``

The primer pulls fuel through the carbruetor
So take your return line from the carb. and hook it to the inlet side of the primer and the other side
of the primer bulb transtions into the fuel tank.
You know when you have hooked it up right when you press the primer it fills with fuel and dumps back into the tank.

The longest, and sometimes smaller in diameter of the two fuel lines, goes from the carburetor to the bottom of the tank. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.

The other fuel line goes from the primer bulb to just inside the tank, (about an inch). make sure that you get the right size fuel lines. The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank.

(HINT): When feeding the lines through the tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.

If you need further assistance, just let me know.

it could be a pin hole leak in the primer bulb.

One fuel line (the one with the fuel filter in the end of it), comes out of the 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 fuel line goes from the top fitting on primer bulb to the top fitting on carburator. That should be the correct fuel line routing. Hope this helped and best wishes.

need brand name of your unit, but reading what you have I will say that the thick one from tank goes to carb and the thin one goes from primer bulb to tank as a return, for fuel. need more info!!

IT SOUNDS LIKE A TWO CYCLE ENGINE TO ME. THE HOSE GOING TO THE PRIMER BULB GOES TO THE HOSE THAT SITS ON THE TOP OF THE TANK AND DOEST GO IN FAR AT ALL AND IS USUALLY THE BACK. THE OTHER HOSE GOES IN THE NID PART OF THE TANK OR THE PART THAT THE GAS IS AT ITS HIGHEST POINT IN THE TANK WHEN THE UNIT IS IN THE POSITION MOST LIKE IT IS WHEN IN USE USUALLY THIS HOSE HAS A SMALL FILTER IN THE TANK. THIS SYSTEM OPERATES ON PRESSURE. WHEN YOU PUMP THAT BULB, IT PRESURIZES THE TANK FORCING GAS UP THROUGH THE OTHER LINE TO THE CARB. IF YOU ARE SYING THERE IS A 3RD HOSE HMMM, THAT PROBABLY GOES TO THE MIDDLE PART OF THE CARB

does it have a pump bulb on the side of the carb? if so,it could have a pin hole in it a be sucking air.

The linefrom the tank with the filter goes to the mixture inlet on carb. The fuel return goes to the suction side of bulb. The bulb outlet line goes to the tank. Hopes this helps
