Great video. I replaced my fuel filter and of course had problems starting my 1998 Beetle TDI. I was able to fill the injection pump from the hose fitting that you reference at the 2:56 mark. I used a brake bleeding hand vacuum pump like the one you reference. It took quite a while to pull diesel, but once I had pulled about 400 millilitres of bubble free diesel I decided to then focus on the injector lines. While my wife turned the car over I monitored the loosened line connections and sure enough diesel began to squirt. I closed the first line and the car began to come to life. By the time I had the final injector line tightened the car was idling beautifully. Next time I believe I will prefill the filter with clean diesel in order to avoid this awful problem.

I used my mk4 diesel golf to prime my my wife's mk4 diesel golf (both AGR engines). I hooked fuel return from injection pump on my car to wife's car fuel filter input (wife's car got new filter + injection pump got all new seals). I put short piece of see through hose on wife's car injetion pump return to filter. As I started my car fuel from injection pump return entered wife's car fuel filter -> injection pump -> return line to wife's car tank. As bubbles mostly stopped in the short see through hose, I stopped my car. What I did not anticipate - there was residual pressure between two pumps and as I disconnected the transfusion pipes some diesel squirted out. Otherwise vorked out well.

I adapted this process to my 2011 golf TDI common rail. I did an intake and throttle body cleaning so had the rail off and all the HP lines drained. Using the bleed off line into the filter, I pulled a vacuum using a fluid extractor. There is a valve that restricts flow from the fuel filter to the HP pump when the engine is not turning, so I could not fully prime using vacuum alone. The valve is not fully restrictive though. Some fuel does get pulled through by vac. Enough fuel to prime the HP pump can be pulled by vacuum alone. I just had to let it hold a vacuum for a few minutes. Then I blocked the fuel filter's bleed-off line in and did a couple lift pump primes and then cranked. It took about 3 or 4 five or so second turns to get it to start up. Once running, I let it run until the vacuum extractor had equalized pressure and shut it off. That was it. No problem with any air in any HP lines. It was a big of a mashup of a vacuum coolant fill and the vacuum priming shown here but using cranking to get the HP valve open. Because the HP side of the fuel system is so tight, you can pull a hard vacuum on it for a long time and get all the air out without worry about lines collapsing and trapping air. Then when the engine turns and the HP pump starts flowing, all the vacuum is filled with filtered fuel. Bonus here is that potential contaminants introduced during the whole maintenance get well flushed out.

I just changed my Fuel Filter and despite priming it - ran briefly now it's a no start. Didn't know about priming the pump - I have a Pela Oil Drain suction pump will try tomorrow -thanx. TDI servicing is like a black Art!

So on my TDI ALH (2002) I sucked the fuel back into the injection pump, primed the pump, bled the injectors, turned it over, re-bled the injectors and got it running. Then, a poorly JB welded steering pump pulley fell off and grenaded my accessory belt. (It ran 400 miles before the JB weld failed, which I figured JB weld woulda lasted. My friend put the JB weld on) Anyways, I build a whole new bracket for the steering pump 10 months later. However, the fuel when I try to pull it through to the injection pump SUCKS ITSELF back toward the fuel filter. Gunna try to use a vacuum on it tomorrow and prime it that way. Its just fighting me.

Great video, How would you proceed in order to bleed the tandem injection / vacuum pump on a MK5 BKD 2.0tdi? I have re-sealed the tandem pump and can't start my engine. A fan from France.

Thanks so much. What would be the best process procedure to test if indeed all hard line nuts are dribbling fuel where they interfaced the injectors? On my MK4 ALH I have before had ONE stuck open delivery valve on opposite end of hard lines threaded into injection pump and therefore NONE of the lines built up any fuel pressure at all, they were all bone dry. I have added a newer BEW TDI fuel sending unit in fuel tank as it has an internal priming pump to help prime the injection pump. What should I test? Thank you.

Replaced everything except the tandem pump. New fuel pump New fuel filter New EGR New turbo cassette new injectors. Car runs like crap. Idles ok but won't rev consistently over 3/4rpm. This all started with a howling turbo bearing.

Dealing with a customer right now who has HPFP failure. He needs that repair plus due for TB, plus needs DPF work. And he still owes bunches on the car. :( sad face

I have an 84 1.6 diesel and I’m doing this process. If one of my injectors does not spray like the others. What could be the issue?

@@CoolAirVw I noticed I’m missing a copper washer on the bottom side of the prime bolt I’m taking out against the pump. Might be causing a small air leak through that?

Using an AC vacuum to pull from the pump and I'm not getting a steady stream. What I get instead is spurts of fuel coming through and I can hear air travelling through the T fitting in the fuel filter. My guess is that the T fitting isn't making a proper seal causing air to get through instead of pulling fuel from the tank. Any tips? Driving a 98 AHU, this was supposed to be standard maintenance, as the car was driving just fine prior to attempting to change the fuel filter.

t fitting is the return line

@@CoolAirVw I understand. What I'm trying to say is I can hear air travelling past the T fitting and the o rings, not the return lines connected to the T fitting. I don't think the T is making a solid fitting atop the fuel filter, and what it sounds like is air getting pulled through the hole in the top of the filter, past the o rings where the T sits and into the receive line instead of properly pulling from the tank when I run the vacuum. I can tell it's trying to pull from the tank because I get spurts of fuel coming through, but I'm still not getting a proper flow.

@@CoolAirVw I threw the old fuel filter back on there just to see, and sure enough it was the filter giving me a headache. Not only do they have the ports flipped on the new filter (based on the direction the arrows were facing), the hole for the T fitting was slightly too big. Guess I should just stick to Mann filters from now on. Excellent video.

Prime injection pump at fuel return line at injection pump. Might need to remove a fitting to do so.

great video, thanks for the info. I've never worked on diesels, only done gas mk2s and 3s. The info you explained was really useful. Out of curiosity, what camera did you use to record this video? I really like the way it looks

Yes.

Doesn't work for me with any of the methods shown other than the vacuum pump. Going buy one now to try it out. It seems like air keeps getting back in no matter what bc you can never fully get it out using diy methods.

Do you have a leak that allows air in? Some air in the lines is normal.

That's the hard way... just take off the rubber line on the right of the right injector and suck it with the mighty vac until the mighty vac cup is half full.

Seems vacuum would be very restricted due to the small size of the hose. Plus there is "stuff" in the fitting. Applying vacuum to the metal line is not very effective as the stuff restricts the vacuum making very slow fill of the IP. I've tried other ways. Removing the line is best.

@CoolAirVw

small hose too restrictive. plus there is "stuff" (checkvalve?) in the fitting at the IP so it doesn't suck well through it so it is slow to prime the IP. We will just have to disagree on this.
