Experienced gardeners share their insights in answering this question :
If your carb has a remote primer bulb, the fitting on the carb closest to the plate that is held on by four screws goes to the primer bulb. The fitting closest to the plate with only one screw goes directly to the fuel tank and is usually the thinner line.

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) 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 return line should direct fuel close to the bottom of the tank and away from the pickup.
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.
The return line opens to the fuel bowl of the carburetor. This return line is separate from the fuel line. A fuel pumping means is connected to the fuel line for passing fuel at a desired rate from the fuel tank through the fuel line to the carburetor.
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.

The supply hose is connected to the fuel filter. The return hose is connected to the top of the fuel tank. The vapor return hose is connected to the charcoal canister.
Most vehicles have rubber fuel hoses connecting the fuel pipes on the chassis to the fuel pump or carburetor on the engine.
The fuel is drawn into the carburetor by the vacuum created on the downstroke of the piston. As air accelerates through the Venturi, it creates a low pressure area and velocity of the intake air increases. This rapid acceleration causes the air and fuel to mix and vaporize.

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.

Replaceing fuel line in polan 3300 chain saw – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
ANSWER : Hi owjbhend…
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line…lubricate the fuel line with some vaseoline very lightly…about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.
Below is a drawing of how to route the fuel lines.

Which fuel line “port/inlet” on the Walbro wt-380 goes to the fuel tank? It’s on a Craftsman 25cc Gas “Weed Wacker” Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer bulb. The carb has two inlets for attaching fuel lines – one to gas tank, one to primer bulb. One inlet is on diaphragm side of carb (side with the two Low/High speed adjustment screws). Other inlet is on “reservoir?” side (side with air/fuel mixture screw). Which inlet gets the “fuel tank line”? (Other will obviously go to primer bulb. I found all kinds of diagrams on web but none that showed this. Your assistance is greatly appreciated. (Problem occurs when replacing gas lines and forget which line goes where:)
ANSWER : Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does

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.
