Bleeding diesel fuel system

If pressure builds up in fuel tank then tank vent is clogged.
True, but it depends upon the pressure applied. I omitted removal of the cap by mistake, but it needed to be said. Thanks @ruffdog.

Several yrs ago I mistakenly got logged off this site by no fault of mine. I had to contact the site moderator to get logged back onto this site. My handle reference got changed to new member at that time & has just stuck there no matter what my post count is. It hasn't really bothered my ability to post threads so I've just ignored the fact that I have 10,317 posts as a "new member"!!;)

Keep an eys on the time that you actually run the starter. There are very short run times followed by very long let it cool times. Burning up a starter because you failed to adhere to the duty cycle time will hurt your back pocket ALOT!
Bleeding a fuel system is never fast.

Some systems are easier than others. On my Case tractor, I usually just need to get the air out of a couple of injector lines, all the way up to the injectors, and then it'll fire up and clear the rest of the lines on its own. On my VW TDI, though, even AFTER getting fuel right to the injectors, you still have to crank it hard (and have a battery charger ready). I suspect air gets trapped in the injector pump. Rotary pumps are worse for that than inline pumps.
