How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. The return line (blue) comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.
Replacing the fuel hose on your vehicle is going to take time and patience, and it could require getting underneath the car. It`s also going to take the right tools for the job.
The yellow fuel line is 3/32-inch ID x 3/16-inch OD x one foot long and the blue fuel line is 1/16-inch ID x 1/8-inch OD x one foot long. The fuel line fits Blowers, Chainsaws, Trimmers and other gas-powered equipment that use this size fuel line.
Most vehicles have rubber fuel hoses connecting the fuel pipes on the chassis to the fuel pump or carburetor on the engine. Rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.
A typical fuel system

A single fuel pipe runs from the tank, under the floor of the car to a mechanical pump on the engine. The pump delivers fuel to the carburettor. Whenever you check fuel pipes, disconnect the battery to prevent stray sparks igniting petrol or petrol vapour.

In gasoline cars in U.S., the return line was the fuel flow outlet of a back-pressure regulator on the fuel injector rail on top of the engine. It flowed back into the fuel tank.
Primer bulb size: OD 1 3/4 ”, height 1 1/2 ”. Fuel line size: ID 3/16” x OD 3/10”.
Using a fuel line disconnect tool helps you disconnect the fuel line from the connector without causing damage. The tools put the right amount of pressure on the connection to disconnect with minimal effort on your part. Many fuel lines only disconnect using the specialty tool.

I need to replace to fuel lines on a Craftman 32cc trimmer. The old ones cracked apart. 2 of the lines look like 1/8″ OD one line looks like 3/32″ OD. Larger line looks like it hooks to filter, Smaller line to a fitting in the gas tank. I am assuming the smaller line ges to the primer inlet. My question is the lines penetrate the bottom of the gas tank. How do they seal. How do I install the filter and the fitting. I am assuming to thread the new lines in from the bottom of the tank and pull through the gas cap hole. Then I attach filter or fitting and pull back through. So do I pull the line so as to create a seal from the swell caused by the fitting/filter?
ANSWER : Depending on the brand of line you use, Tygon line is self sealing but seems to shrink faster then factory supplied because of the ethanol in the gas. The stone gas filter is designed to fall to the lowest part of the tank, not stop the line from falling out.

Need to replace fuel lines on my Troy Bilt gas hedge trimmer. Where can I get replacement fuel lines… or better yet… what size are the lines and where can I buy a few feet of the lines. Note: I have reviewed the parts assembly and it would seem to indicate I have to replace the entire handle assembly (Part #1) instead of just buying replacement hose(s). Any help to resolve my issue would be greatly appreciated and thanks in advance
ANSWER : Replacement fuel lines should be readily available at your local lawnmower repair shop. Your TroyBilt hedger uses fuel line that is 3/32″ (2.4mm) interior dimension, 3/16″ (4.8mm) outside dimension, with a 3/64″ (1.2mm) wall dimension.
Most manufacturers don’t offer replacement line, only fuel tank assemblies. Find your local shop, and try to get the TYGON brand…it is yellow. Tygon lasts the longest. You should be able to buy it by the foot for less than $2 per foot. You will need 2 feet of hose to replace both lines.

Make sure to clean the in-tank filter when replacing hoses.

Good luck.

The fuel lines have rotted out of the edger gas tank. How do I fix or do I need to replace entire tank with new fuel lines?Since there are no male fuel line connections exiting the fuel tank and just two holes where the lines were, I guess I need to replace the entire tank and get a new one with lines already attached. Thanks.
ANSWER : No you can buy replacement fuel line but you must reconnect the filter in the tank that line goes to the bottom of the carby then out the top of the carby to the inlet on the primer then out of the primer and back to the tank.

How do the fuel lines in a weedeater trimmer pe550 hook up inside the gas tank
ANSWER : I have an older model that has a weighted filter in the tank. The filter flops around and can ‘fall’ into the fuel no matter which way you tilt the trimmer/tank. You should have one in your tank. Feed in the new line and make the end come out the gas cap. Push the filter/weight into the end of the fuel line. Pull the extra fuel line out of the tank to match the original position. You should have cut the new line to approximately the proper or same length as the old fuel line with an angle cut so you could push it into the tank.
