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.
Fuel line. 15 Inches of of 1/4 inch inside diameter hose.
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.
The (clear) main fuel line with the filter (filter inside the fuel tank) goes to the bottom of the carburetor (or the elbow shaped nipple). 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 fuel rail is the last distribution point in the fuel system before fuel is sent to the injector. In return-type systems, each fuel rail is connected directly to the injectors that it feeds and relies on a fuel pressure regulator to relieve excess fuel pressure.
The return line should direct fuel close to the bottom of the tank and away from the pickup.

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 diagram for fuel line in tank fuel filter
ANSWER : The small diameter fuel line that has the fuel filter in the tank on it goes directly to the carburetor (with the built-in primer or externally mounted primer). IF the carb has the external primer, the small line goes to the nipple on the carburetor opposite the end with the hole in the cover. If it has the built-in primer on it, it goes to the carb body on the nipple furthest from the bulb. The large diameter line is the fuel return line and if the carb has the bulb on it, this line connects on the nipple closest to primer bulb.. With the externally mounted primer, this line connects on the longest nipple coming out of the primer and goes to the fuel tank (not the filter though). There is a nylon connector inside the tank that holds this larger line in place. The shorter nipple on primer bulb has a smaller diameter fuel line connected to it and connects to the nipple on the carb closest to the end with the hole in the cover. Built in primer has 2 fuel lines…externally mounted has 3.
