Where does fuel return line go?
Some fuel return hoses will run along the frame of the vehicle and go straight to the fuel tank with little as possible bends. Other fuel return lines have many bends and may be longer than normal. This helps the fuel cool down prior to entering the fuel tank.
How do fuel return lines work?
How do fuel return lines work? In fuel systems with a return line, the fuel pump is continuously pumping gas through the fuel system at a much higher rate than is actually needed. This keeps gasoline in the fuel lines cool and flushes out any vapor bubbles that might form. This prevents vapor lock in your fuel system.
Why do diesel engines have fuel return lines?
Diesel has a return line because the fuel is injected via the Injectors. In a very dynamic and transient conditions, the load or need for fuel varies very radically. in that case the Diesel Injector may have extra quantity at a very high pressure due to the previous demand.
What is a diesel return pipe?
Diesel leak off Pipe (also named Return Line)is used for returning of the excess fuel after injecting fuel into the diesel engine.
Does a fuel injection return line have pressure?
In return-type systems, fuel is returned at a lower pressure than that found in the feed line or fuel rail. These can be replaced and upgraded as required. These regulators work by allowing the line pressure to build to a level higher than normal line pressure before venting excess pressure back to the tank.
How do you unscrew a fuel return line?
Unscrew the fuel return line with a line wrench. Trace the fuel return line to under the truck. Remove the fuel line from the clips. Unscrew the other end of the fuel return line with a line wrench.

Where does the fuel return line start on a PowerStroke?

How often do fuel lines need to be replaced?
The fuel lines on every Stihl engine contain a main or suction hose and an impulse or return hose. These hoses suck gas from the tank into the carburetor and any excess fuel returns back to the tank to be reused. The lines age quickly due to fuel impurities and must be replaced almost every season.
