No I think we were both referring to the big bolt in the middle of the pump head. Where is the leak coming from? If it's from the head seal, you may have pinched the seal or didn't clean the head and the seal groove well enough or perhaps your leak is from the aforementioned bolt in the middle of the pump head. It has a seal that may be leaking and you need a special socket or a customized one to re&re the bolt.

My seal change appears to have been successful as it's been a couple months and it's still dry. BIG SHOUT OUT to Crawdaddy for lending me the tools required and to Nigel/Wingnut for coming through with the seal.

If done carefully, it's not a difficult job, and can be done on the car as per the video, just need to make sure you clean everything well, including the little seal groove and don't pinch the seal on the way back in. I powerwashed the pump beforehand and cleaned it with break cleaner as well.

Default Update:

so I cleaned up the area around the pump using brake cleaner. I removed the fuel injection lines and disconnected all the electrical connections sitting under the injection lines, just to have some room. Stuffed plenty of paper towels to catch as much fuel as I could. Removed the bolt sitting in the middle of the larger bolt with the weird head (pic below) and used this tip (http://forums.tdiclub.com/showpost.p...90&postcount=3) to get the pump on cam. Got the pump head to expose the seal and used a q-tip to wipe off any debris that might have fallen in the groove of the o-ring. Used some air to blow off any loose debris in the gap or on the o-ring itself. Not sure if that did anything but once that was done, I slowly tightened the head bolts (T-30) to get the head back onto the body. Put everything back together and primed the pump using a mity-vac. Anyway, cranked engine a bit and got the engine to run.

checked for leaks and so far, a day later, haven't seen any. I think the most important part is to make sure that you bolt up the head back onto the body of the pump as evenly as you can so that the seal doesn't catch on any side.

Thanks for all the awesome input from the TDI Club community!
