How do you get air out of a fuel line?

How to Bleed a Gasoline Line

1. Fill up the gas tank with fuel.
2. Start the engine but do not allow air into the system. Have a friend turn the key in the ignition to “Start” for approximately 3 seconds.
3. Allocate approximately 20 minutes for the engine to sit if flooding occurs while bleeding the fuel lines.

What causes air in the fuel system?

Air bubbles are caused by any air leak on the vacuum (suc‑ tion) side of the fuel system from the fuel tank pick‑up to, and including the lift pump (see Figure 1). If there is an air leak in the fuel system, air bubbles will be present in the clear cover of the Fuel Pro.

How do you bleed air from a fuel rail?

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.

How do you set the timing on a fuel injection pump?

If you decide to alter the fuel injection pump, you’ll need to:

1. Use a socket wrench on the front camshaft bolt to hand-turn the engine clockwise until the first cylinder is at TDC.
2. Both the intake and exhaust valves should be closed, and the TDC mark should be aligned.

How do I test my injection pump timing?

Turn the engine so that the unit to be checked is toward the TDC of compression stroke (plunger upstroke) so that hair line marking on plunger and pump body are coincided. When hair lines are coincided, stop turning and check the mark on the fly wheel whether timing is correct or not.

How do I check the timing on my auxiliary engine fuel pump?

In Auxiliary Engine

1. Remove the fuel valve.
2. Insert the rod onto the piston (mark on rod and flywheel)
3. Turn crank until the rod previous mark.
4. Make the second marking on the fly wheel.
5. Mid point between the two points is TDC.
