Over time the rubber lines that transport diesel fuel to the engine develop dry rot cracks and loose their ability to seal on the connections on the fuel filter & injection pump. This creates problems, including:
The OEM VW, factory fuel lines are nicely molded, paired lines that curve around engine components nicely. On some models the factory line is a hybrid of molded fuel line and hard plastic line. Even better, sometimes the hard plastic lines are clear. The clear lines allow you to inspect for air leaks – large bubbles that grow when the car is off or a steady stream of bubbles while running are signs of trouble. here

The good news is that the OE fuel lines are available easily. Check out the Fuel Filter to Pump Line for ALH, Fuel Filter to Pump Line for BEW and others. The bad news is that they are EXPENSIVE. Some are as “cheap” as $129.99, others can pass $300 dollars. This is crazy. here

Diesel fuel is closer to oil than it is to gasoline. It too has a distinctive odor, and also feels slick between your fingers like oil does. Diesel is not as volatile as gasoline, but you still need to address a diesel fuel leak sooner rather than later.

Diesel fuel works best under pressure. Diesel engines use this high pressure in their fuel systems to atomize the fuel when it’s injected into the combustion chamber. This is the heart of the system, really. If there’s a loss of pressure or there’s air in the fuel system, the engine won’t run. So if you have a diesel fuel leak and your engine won’t start, repair the fuel leak, bleed the air from the system, and try again.
If no other leaks are found, return fuel lines to original configuration and resume checking for leak with bubble test or visual inspection of pressure characteristics (deteriorating vacuum). here
In this post, you’re going to learn how to find air leak in diesel fuel system. Aside from that, we’ll also talk about how to bleed air out of diesel fuel system.
Let’s now look at how to find air leak in diesel fuel system. A common way to find air leak in diesel fuel system is by using a “bubble test.” more
The most common reason behind an air leak are cracks on lines near bends or at welding joints. If you notice that your engine is struggling to run, then the air leak could be caused by a faulty filter or a worn gasket.
The first step to fixing air leak in diesel fuel system is to seal the leak through a process called machining. [links]
