Do you need to bleed a fuel system?
Most secondary fuel filters are equipped with a bleed screw. Then you must bleed the high-pressure fuel system, which is done by loosening the union nuts between the top of the fuel injectors and the fuel line; it just takes a turn or two. Once loosened, use the starter to crank the engine for 10 seconds.

What causes a diesel engine to bleed air?
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. Here are the steps to take in bleeding air from a diesel fuel system: 1. Turn off fuel valve.
When to close bleed plugs on diesel engine?
Close bleed plugs after all air is removed from the fuel tank, filters, settlement bulb, and fuel pump (only one at a time working through all bleed screws beginning closest to tank and ending at nozzles if necessary). 10.
