How do you bleed air from injector pump?
To purge air from the low-pressure side of the fuel system, open fuel-line unions and bleed ports downstream of the pump, one at a time, beginning with those closest to the pump, and continue pumping until fuel, and not air, runs out.
Why do you bleed air in a diesel injection pump?
When reaming the fuel, fuel pumps suck some air. It’s important you bleed the air out of the fuel circuit prior to refilling to maintain your fuel pressure and to keep your engine functioning smoothly.

Can you prime a fuel injected engine?
Gassing and Priming

Why do I have to prime my fuel pump?
The fuel pump has a check valve built into it that is supposed to keep pressure to the injection system when you shut down and vehicle sits. If the pressure drops then the pump has to prime the system to bring the pressure high enough to start and run the engine.
How do you bleed a Stanadyne injection pump?
To bleed the fuel filter loosen three turns the bleed screw on the IN side of the filter. Pump the priming lever on the fuel lift pump until fuel spurts out without any air bubbles. Retighten the screw and move on to the OUT side of the filter and repeat the purging process.
How do you get rid of an airlock in a diesel engine?
You can attach the fuel lift pump to the engine and filter the engine fuel. Keep an eye on the bleed screw when pumping either the lever or the plunger. A bubble will form as the air leaves your system after it has departed. A splash of water or other absorbent material along with your rags can wipe the fuel clean.

What is airlock in diesel engine?
When you change a diesel fuel filter, run out of fuel or disturb the fuel system, air is trapped. When you try to start the engine this air acts as a lock, preventing the normal supply of fuel into the cylinder.
Why do I have to prime my diesel engine?
When priming a diesel engine, you will ensure that your engine starts up because the fuel filter has diesel available and that all air is removed from the fuel system. This may be necessary if you are changing the fuel filter, or if your diesel engine runs out of fuel.
How do you start a fuel injected engine that has been sitting?
The most appropriate way to launch any EFI engine in a car or truck is to turn the ignition key right up until it fires up. Your fuel rail needs to prime and when your fuel pump relay has been shut off, start working into crank mode now. The proper sequence is executed, a hold is given, and the crank is clicked.
How do you lean out a fuel injected engine?
Half a turn in either direction should ensure the smoothest idle speed you can find. To idle the idle, you have to turn your screw clockwise and half clockwise from the middle position. To balance the fuel mixture, position the screw at an optimal level so the engine’s idle remains constant.

How does a Stanadyne injection pump work?
The Origin Of The Stanadyne DB2 Pump
With the DB2, engine rpm is controlled by a rotary fuel-metering valve. When the accelerator is depressed, the throttle linkage opens the metering valve in the injection pump, allowing more fuel to be delivered to the pumping chamber.
