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. here
Check to make sure there aren't pinholes in your fuel tubing. You can consult your automotive manual, or get the assistance of someone who is mechanically savvy if you are not. Locate your fuel tubing, and remove it.
Locate your mounting screws. Again, consult your automotive manual or a professional if necessary. Remove the screws and place the tubing above and below each screw. Tighten the screws securely in place. [links]
Along with the joy and freedom of owning your own vehicle come the difficulties of repairs and maintenance. If you want to keep enjoying the delight of the open road, you'll need to know how to diagnose or fix a few things, or know a great mechanic. Here are a few ways to remove air from a fuel line, a truly problematic experience. Air bubbles in a fuel line can lead to stalling, hiccuping or refusal to start. Keep your fuel lines free of air to help keep your car running smoothly.
Another reason you may have air bubbles in your fuel line is due to vibration. An easy fix to this is to insulate your mounting screws with fuel tubing.

Anything connected to the top of the tank (sender, fill, vent) should have no effect, correct? I mean, they can't cause the air leak, right? more
Double check all connections. Double clamp to make to make sure. Water separators are notorious for leaking. more
If the fuel pump is doing its job it will pull the fuel over the top of the hills.
If it were to move the vapor bubbles as far as the carburetor, the float valve would just stay open a few milliseconds longer as the bubbles were sucked down the carb throat.
Here is a shot of the tank as I found it. The fitting has since been cleaned and replaced, the shut off valve eliminated for now.

The fuel is dispersed from the injection pump to the combustion chamber via a fairly simple process. Pressurized fuel enters the fuel injector. Based on a signal from an electrically controlled solenoid valve – the solenoid valve acts as a type of on / off valve – the fuel enters a plunger, which prepares the fuel for the final exit. When the fuel leaves the fuel injector, a spray tip distributes the fuel as a fine mist.
So what does a diesel fuel injection pump do? It’s about as simple as you can get: fuel injectors supply fuel to the engine’s internal combustion chamber. High-performance automobiles usually have one fuel injector per cylinder, and the pump “injects” fuel into the combustion chamber – hence the name “fuel injector.”
From these two things, a host of problems can surface. Let’s take a look at 4 common fuel injector pump complications. here
The other day I drain my antifreeze change the thermostat and now I have air in my cooling system lines what is the best way to get the air bubbles out I have tried everything and still is not working
My car has an automatic transmission.
The cooling system does not need any special procedures to get the air out of the system except to have the heater to on and warm setting. This will allow the coolant to flow through the heater core and out to purge all the air out. You should start by filling the system and then start and let it run at idle until the thermostat opens. Once the thermostat opens then coolant level will go down and need topping off. Once the system is topped up then install cap and accelerate the engine up to 2000 rpm for 30 seconds and let it idle. Do this a few times then let idle and shut off engine to let engine cool and then top off coolant. The system may need to be checked each morning to bring the level to the cold fill line before starting. This should get all the air out of the system.

once I get my truck started it will run all day, after I sit for 10 minutes or ten hours, I lose my prime. I do see small bubbles appearing in my water and fuel separator more like small form bubbles. I know the fuel system is sucky air where do I begin, I did notice when I use the prime plunger and the main filter to prime the system it leaks fuel out of the plunger, in my opinion if it's leaking fuel it's sucking air.
Is there any other places where I should be looking, did replace the fuel pump still the same problem, next on my list is the main fuel filter assembly?
