Who ever showed you how to bleed brakes lied to you, If you keep on pumping like that you will suck air back in, and you also aint really moving that much fluid because every time you release with the tbe in the jar ally ou are doing is sucking the fluid back in that you just squirted out.
The correct way you do it is have you friend pump a certain amount of times I always pump 3 time hold the pedal while other dude craks the screw and I would hold the pedal to the floor untill the the bleed screw is tight again.
You can buy some speed bleeders to replace your stock bleeder screws and you can do this yourself, I got them for my Jeep as I have a leak in the system that only shows its face after it has sat for awhile and they work wonders.

...vaccum has no bearing on bleeding brakes...other than it makes it easier to pump the pedal...but most prefer to bleed with the engine killed...so after one pump of the pedal (on a engine not running) you are out of vaccum, wheather its diesel or gasoline...redzone...

Boy I love it when people jump to confusions. Hey redzone if you are going to quote someone please take the time to read the entire thread so that you are familiar with all of the positions and angles in which the topic was approached from. There is a good chance that if we have posted on the issue that we are aware of how the brake system works on a vehicle, but it is quite difficult to diagnose an issue from multiple states away, so we are all doing our part to try and HELP the best we can.

What we are trying to get across is that the OP has done everything from replace just about every major component in the system including lines to putting teflon tape on the fittings. He has even replaced some of the newly purchased components in the belief that they were bad from the store. We were simply clarifying that his vehicle is a diesel and not a gas setup. The difference of which would simply include a vacuum pump. Nothing more nothing less. I was not now nor was I previously indicating that the vacuum pump would make a difference on bleeding the system, however the OP was complaining that his pedal would go to the floor even after multiple bleeding sessions. Like I previously posted, I wasn't sure if the fact that the vacuum pump may be weak would allow the pedal to go to the floor and was leaving it open for someone with more expertise in the diesel area to either confirm or deny whether or not that is the case.

No problem man, I've done it way too many times myself. Basically, the prob is that the brakes bleed fine without it running, but when he drives it the pedal goes to the floor. And a mechanic told him it was the vacuum pump. In other words , what he said , speeddemon that is.

...JMO...but i would have a hard time believing a new vaccum pump will make a difference...but hey, i could be wrong...
...again...an interesting thread...
