Fuel line routing

Hi,

Please call Toro in order to get the fuel line routing diagram for your machine. Their phone number is 1-888-384-9939.

Thank you.

Make and model please.?

Where is the fuel leaking from exactly?
Generally you don't get diagrams od fueling routes. They often go via the most direct route from tank to carb/primer

Schematic?
WELL, if it is a gasoline engine (you did not specify), there isn't much to the "fuel system..." only a single line with one or two pumps routing fuel to the fuel pressure regulator, and a single fuel line from the fuel pressure regulator routing bypass fuel back to the tank. Oh... and the fuel rail and injectors, which are all connected to the fuel pressure regulator.
If it is a diesel engine, it is even simpler!
Why would you need a diagram??

in 1980 it is pretty much forward from fuel tank to fuel pump from fuel pump to carburetor ....the return line from pump to tank

hope it helps

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, hh

Hi.

There is no "diagram" showing the whole routing of fuel lines in the bike. You need to use different diagrams in Fuel System section of the service manual. Fuel system section starts at page 15 in service manual, but what you really need starts at page 40. I have posted fuel service manual at the end of comment.

There is one forum where users discussed the routing. One user has colored the diagram from service manual to indicate lines routing. Here the diagram:



Here the forum, I quote:

"The red and yellow are the fuel lines that go to the petcock. The green one you left unmarked also goes to the petcock. The line with a question mark is a vacuum line that connects to a part in front of the battery along with the larger lines to the cylinders."

Here the service manual in PDF format.

It's hard to find diagram for older bike.
I got the pic from the tank to pet ****.

all main fuel lines should route to the fuel filter first. then to a "fuel pump" system, then up into the fuel rail or t-fitting. if you see a smaller extra hose coming off the tank that is just a purge vent tube overflow line. That should drain into another funnel like collecting device that will route to it so as to not drop onto the hot running engine. Follow the main line from the fuel selector on/off/res... there better only be one line... or that means you"ll have two fuel filter/ pump systems, i wouldn't want straight unfiltered fuel going directly into my carbs. (Plus that would mean your pump and main filter are in the tank) this could be a possibility!! Let me know if im wrong, call the dealer and ask, but this is 1993 technology not 2003 it should be very basic.

Jimmy there are no Poulan drawings with fuel system detail worth the ink it takes to print them, but that is all there is.

Routing runs from fuel tank to carburetor, (if equipped) through carburetor to primer bulb (once compressed bulb draws fuel as it returns to normal) , bulb (as it is compressed) returns displaced to fuel tank. HTH

I'm so confused. This is reported as a Poulan and McCulloch pole saw, which one? Is it a pole saw? That is the only 445 Poulan I can find. It is reported as an electric but has a fuel routing problem.

If it is a Poulan Pro gas pole saw it is here: PP445 Gas Pole Pruner
The fuel system routing is terrible, but it is all there is.
Fuel Routing follows:
Tank to carburetor (hose in tank with filter on free end)
Carburetor to primer (primer draws fuel from the tank through the carb)
Primer to fuel tank (returns any excess fuel to tank when pushed) HTH
