Here is an update,
Transfer Pump ------------------ Some have suggested that I am asking for trouble trying to reuse the Pierberg pump that was siezed and now seems to be spinning. There might still be chunks of plastic or other debries in there. I am going to listen to you all as you know way more than I do and order a new one and the filter that comes with it. Mark and the team at GermanAutoparts have always been great and I ordered the Pierburg form them many moons ago when I had someone replace it for me. Top Gasket --------------- Thanks Charlie for the part number (6N0-919-133), I will check the current price at VW. Inline Reducer for Transfer Pump Motor ------------------------------------------------- Thanks Joe and Galen for the OEM part number (357919133). This part seems to cost $80-$100 online. Some people have just used a piece of hose: http://forums.vwvortex.com/showthread.php?4691808-DIY-In-tank-Transfer-Pump&highlight=transfer+pump (seems unreliable considering that the pump side is smaller than the top side) Chad has had luck using a 5/16" to 1/4" Brass reducer. I am going to try this and see if the threaded side doesn't leak: http://www.ebay.com/itm/5-16-ID-Hose-Barb-x-1-4-NPT-Thread-Air-Fuel-Water-Solid-Brass-Fitting-Coupling-/310381038541?pt=Motors_Car_Truck_Parts_Accessories&hash=item484426cbcd&vxp=mtr I am trying to track down a brass version of this as an alternative to the OEM part: http://www.amazon.com/dp/B008V22EN0/ref=biss_dp_sa1 (Not sure if Chrome is ok in fuel, probably not.) If I can find the brass double barbed 5/16" to 1/4" brass reducer, I will order that - if not I already ordered the threaded one. We'll see how this OEM alternative attempt works out. Proper Clamps ------------------ I see the result of using silly regular clamps that were used on my car when the transfer pump was replaced way back when. I am going to order some proper fuel line clamps. (Thanks Charlie and Chad for schooling me on clamps) http://www.germanautoparts.com/Volkswagen/Golf/Fuel/98/1 Submersible Fuel Line (for in between the transfer pump, the reducer and the main transfer pump assembly all inside the gas tank) --------------------------- No matter where you look, it seems this is only available in one foot lengths. So I might bite the bullet and buy 5/16" submersible hose and 1/4" submersible hose. I can reinvest the money saved by not buying the OEM reducer if that alternative works out. Seems to be $20 for each one, and a lot of seem to try regular fuel line and sometimes it fails a year or two later from being in the fuel. Gas Tank ----------- I am going to drain and vacuum out any crud in there. I am concerned with taking it off. Any safe way to clean/flush it out? Main Fuel Pump -------------------- I will be careful when trying to remove the main fuel pump (thanks for the warning Charlie) Chad was kind enough to sell me a known working main fuel pump and housing so I can at least be sure I have a working pump in the mix as I troubleshoot. Large Plastic Nut on top of Transfer Pump --------------------------------------------------- Thanks for the part number Charlie (191-201-375A-01C), mine is a bit beat up after a couple of removals with a hammer and screwdriver. Larger channel locks are definitely in order. Guess this is one of those 'special VW tool needed' parts. I'll check at VW for the current price on this. Thanks all for the great advice and education, as I progress on this revival attempt of the car I am learning more and more and getting to know the car better which makes it all seem a little less daunting.

Larry, I replaced the tranfer pump in my 8V Golf a couple of years ago. Back then I found the gasket part number had been superceded with part # 6N0-919-133. IIRC, I could not find an alternate source for the gasket so I got one from VW for around $17 back in 2009 according to my records. I got the transfer pump and screen from germanautoparts.com. They sell the OEM Pump ($70) and an aftermarket version ($43). They also have the fuel line clamps if you cannot find them locally and cheaper. http://www.germanautoparts.com/Volkswagen/Golf/Fuel/98/1 I have used this company for years for parts for my A1s and A2s and they have always been great. Best of all they don't bend you over when it comes to shipping costs. Also be careful when tightening the plastic nut that anchors the transfer pump assembly. If yours is cracked or in bad shape you may be able to get a new one from VW. Part# 191-201-375A-01C. The one I got from VW was about $10 back in 2009. Whatever you do be careful if you have to replace the main fuel pump. The fuel lines that connect to the main fuel pump and fuel accumulator are usually rusted beyond hope, break easily and have to be replaced. Finding replacement lines can be a royal PITA. How does the inside of your fuel tank look? Are you flushing the tank out to get the rust/crap out of it? Good Luck and keep us posted.

Hi all, As you all know, my 16V has been out of commission for a while. With much help from Chad from the list, I have been narrowing things down to fuel delivery. Likely both the transfer pump and main fuel pump seized. I have removed the transfer pump and confirmed that it was seized. I was able to free it up after removing a bunch of the fins that had broken off and were keeping it from spinning. 10+ fin pieces came out by the time I was done. Mental note: the metal is soft, don't bang it as hard as I did or you will dent it. After getting the little fins and one tiny rock out, the pump came to life with a little puff of dust - once I applied power. I found that the piece that connects the transfer pump to the housing (what is this called?) is not in good shape. Is this piece sold somewhere or is there an aftermarket alternative? Here are picts of the gremlins and the piece I am refering to: https://www.dropbox.com/sh/gx9d5u1ju0oo1t2/fWoRn5fDGz Here are picts of me removing the transfer pump: https://www.dropbox.com/sh/4vdx5cvto03n4na/b6HZAEttqk I will have to replace at least the top rubber gasket, transfer pump filter and possibly the pump itself and maybe other pieces. Will also need gasoline submersible hose pieces (does anyone know what sizes they should be, is there a rebuild kit maybe?) and proper fuel line clamps. If anyone has any thoughts on how to put the transfer pump back together and replace the worn pieces, so I can see if the car starts - let me know. Thanks all, I hope you are all enjoying your 16Vs.
