Fuel line in tank dry rotted how do you replace

Buy some new fuel line then put the line in from the motor side into the tank and feed up and through the opening on the tank. Then you can put on a new filter with a tiny clamp then put it back into the tank making sure the filter is resting on the bottom.

The diameter of the fuel lines are bigger then the holes in the fuel tank. Make sure u get the right diameter fuel line. The fuel lines are basically crimped by pressure. Sometimes its like there welded in place. There should be two fuel lines. One is short goes from carb to tank. When you use the primer bulb it takes fuel from tank through carb spits it back into tank. The longer one has the fuel filter on it. Empty all the gas from tank. Look inside of tank with a flashlight and try to locate the fuel filter. Take a piece of wire make hook on one end. Try to snag the fuel filter and pull out. Might as well replace filter while it is out. Take a pair of long nose pliers and grip the hose as close to the hole as possible. Try to pull with even pressure(no yanking). The lines may break because they could dry rotted. Make sure to hook lines back up the same way they came off carb.

Tank should not have a breather, the fuel cap does that function. Check your fuel lines and where they penetrate the tank. Today's fuel will eat the fuel line over time and there is also dry rot. The fuel lines on these need to be monitored over time to ensure continued safe operation of small engine equipment.

I hope this is helpful for you.

There should have been a fuel filter attached to the fuel line. So when installing quite tricky, put line in tank, place filter on end of line while in the tank, let filter lay flat on bottom of the tank.
In those carbaretors there are gaskets and a diaphram. After awile they ware out and the diaphram which is rubber gets hard, so it will no longer pump fuel. You can buy everything for the cab in a kit. I hope this helps you.

By your question, I assume that the fuel line runs dry after the engine runs a few seconds. The first thing to check is for a plugged fuel filter in the tank and the condition of the connecting fuel lines for rot, hardness, or cracking. If the machine has a primer bulb, does it pump fuel into it after several pumps? Remove the line from the primer that goes back to the tank to make sure it is pumping fuel from the carburetor only. If you replaced any lines, they may have been reconnected incorrectly. Hope this answers your question!

Have it replaced at a lawnmower repair shop.
1.) Have them check the grommet (black round rubber like a thick coin with 2 or 3 holes), replace it if it is crumbly. It holds the fuel line and the fuel vent line - if your trimmer has it. Grommets on the average cost about $6.00. Not all trimmers have fuel grommets, some of them only have holes right on the fuel tank. 2.) Replace the fuel line with Tygon fuel line hose. Tygon can withstand UV light, petroleum, high and low temperatures while retaining its shape. Just make sure the replacement tube is of the the same inside diameter. For a small piece of Tygon hose, ave. cost no greater than $8.00. 3.) Replace the fuel filter. The one inside the tank, connects to the end of the fuel line. Fuel filter, good ones are about $4.00.

it's in the fuel tank it goes from the carburator into the fuel tank and replace the fuel filter while you have the tank off.

First, you sould have one with a filter in the tank going to carb. Next run one from tank to primer bulb and from one from primer bulb to carb.

Was there any gas in the car before you added 5 gallons? If there was, it is the problem. The gas goes bad, especially if left in the car unused that long. The system will need to be flushed out (lines, tank, carb/or injectors cleaned.
Also, carefully inspect the entire brake system, as flex. rubber lines can dry rot, steel lines may be rusty (if rust was present when parked, even though the garage is dry). You will probably need to disassemble the calipers and brake cylinders, clean them, and flush the system out. Your tires probably need to be replaced also, as they may fail under high temp conditions (dry rot). I have stored cars over the years, not always in the best conditions, and the worst thing for a car is to have it sit unused.
