  1. Hello everybody. Thank-you so much for your comments. I really do appreciate your help. After liasion with the very helpful Adrian, at Kingsley Cars Oxford, we have figured out that the second nipple or spiggot is used on only a limited number of classics. This is what he sent me: "There should only be the one nipple which goes to the fuel pressure regulator. BUT on some models a vacuum pipe, from a second spigot, operated a hot water valve via an electrically switched valve. The hot water valve is located on top of the right hand rocker cover in a Y connector in the water pipes. The electric valve is located on the bulkhead just behind it. http://lrcat.com/#39/4/49254 The tail of pipe number 8, I think, should go on the 2nd nipple." Indeed my classic does have this hot water valve so I have ran a pipe from the 2nd spiggot to this valve. I will try it at the weekend and report back. Those guys at Kingsley Cars are very knowledgeable and for someone to e-mail at 21:30 says alot for the commitment they have. Thanks again David.
  2. Hello I have a 1994 LWB Classic Range Rover 4.2 that I have just finished restoring and I am a little confused on where 1 particular vacuum pipe goes. On the rear of the plenum chamber I have 2 small male nipples where the IAC screws into.The part number for the plate where the nipples are is MKF100200. I have worked out from pictures that one vacuum pipes goes from 1 of the nipples to the fuel pressure regulator but I am stumped by the other nipple. The vehicle runs rough on idle if the spare nipple is left open and once blocked the engine idles fine. I take it that more air is been forced into the plenum chamber confusing the ECU. If you place your finger over the nipple it is sucking air rather than pushing air out. I have searched online for the plate on which the nipples are attached and they all seem to only have 1 nipple. What I am wanting is a diagram of where the vacuum pipes go as at present I have simply blanked it off with a piece of tube with a stop in the end. Any help would be appreciated. Regards David
