If This Is To Remove Air From Fuel Lines. Forget It. You Do Not Have To Bleed The Fuel Line.
you need to crack loose the injectors and let the fuel pump push some fuel (and air) out around them then tighten them back up.
The bleeder screw or air vent screw on a fuel injector is used to remove any air trapped in the fuel system. It allows the air to escape, ensuring that only fuel flows through the system and preventing air bubbles from disrupting the fuel flow or causing issues with engine performance.
A FUEL SYSTEM stores, and supplies fuel to the cylinder chamber where it can be mixed with air (air & fuel ratio) to transmit power
Engine cooling system is not a closed system you can't remove the air.
The filters such as the air filter, the oil filter and the fuel filter remove harmful contaminants from entering the system.
When your Astra diesel runs out of fuel, air can enter the fuel system, leading to a loss of fuel pressure and making it difficult for the engine to start. Additionally, diesel engines rely on a specific fuel injection process, and without fuel, the injectors can become clogged or air-bound. To resolve this, you'll need to prime the fuel system by refilling the tank and possibly bleeding the fuel lines to remove any trapped air.
there should not be any fuel in the exhaust system, if there is, you have serious problems
There is a schrader valve on the fuel rail that will allow you to blled the system. This is not normally necessary as the air will be pushed out by the fuel pressure.
no such thing. running the car unignited on "on" will prime the system and remove air, water, and will renew pressure. remove fuel pump fuse under driver's side dash and turning car "on" will drain fuel pressure. battery kill for one minute will reset ecu. these are all the things you can do to cause fuel system to revert to "default" settings.
Before you start the refuelling process. Ventilation will remove fuel vapours from the air inside the cabin.
Under the fuel tank. You have to remove the fuel tank to get to the air box, which houses the filter.
