Can a purged fuel injection system purge air?

A properly-purged fuel injection system should dribble diesel fuel immediately out of the lines. If nothing comes out, this affirms there is air in the IP and/or lines. First, check to make sure you are getting fuel to the Schroeder valve on the diesel fuel filter. Read this article FIRST which explains how to check your Schroeder Valve.

How to remove air from fuel injected lines?

Locate your fuel tubing, and remove it. Once you have removed the tubing, clean it well and place it in a clear container filled with water. Blow into 1 end of the tubing and look for any bubbles in the water. If you see bubbles there are holes, and you will need to replace the tubing with new tubing.

When to torque down diesel injector lines and purge air?

As soon as possible, torque down the remaining injectors. Any delay will result in diesel fuel spraying all over the engine bay. There may be a few minutes of a rough idle, because remaining bubbles might need to work their way through the injectors. At this point, the IDI should be idling.

How do you fix a bleed plug in a fuel pump?

Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator’s manual.) Pump several times until full flow, without air bubbles, escapes from the bleed plug holes. 8. You may need to bleed filters, fuel pump and lines to the injectors.
