When to install a fuel return line or not?
Go with what you got for now and see how it works. If you have bad “pressure creep” at idle or the pump is howling loud enough you can’t stand it, install a return-style system. 1) The pump is pumping at full capasity therefore it is kept cooler than a pump that is dead headed.
Why do I need a return line in my EFI?
EFI systems require a return line to move unneeded fuel from the fuel injection system back to the fuel tank. This process of cycling fuel from the tank to the injectors or throttle body and back to the tank is a complex process.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
What happens when the fuel leaves the injector?
When the fuel leaves the fuel injector, a spray tip distributes the fuel as a fine mist. Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.”
What happens if the return line of an injection pump Kinks?
Diesel Fuel Return line Kinked. This will kill your engine. The diesel engine requires a supply fuel line (fuel from the tank to the engine) and a return fuel line (fuel from the engine back to the tank). What happens is that the injection pump will supply more fuel than is necessary to the injector.

What happens when you use an injection pump on a diesel engine?
This will kill your engine. The diesel engine requires a supply fuel line (fuel from the tank to the engine) and a return fuel line (fuel from the engine back to the tank). What happens is that the injection pump will supply more fuel than is necessary to the injector.
How can I tell if my injection pump needs repair?
Injection pump needs repair No Start, no fuel delivery to Injectors 1. Electric Shut off solenoid failed or not getting power 2. Shut off linkage in stop position. 3. Check for insufficient fuel supply, replace fuel filter. If equipped with a fuel supply pump check for minimum of 2-3 psi fuel supply pump pressure. 4.
