the spider assembly is simple and easy, your best off just purchasing a new one, and it only goes in one way and the lines are pretty much orinated to go to the correct cyclinder. they just push in and thats it. I wouldnt even mess with the old one your just going to be chasing issues, this way you know its going to work 100%.

second thought you didnt mention the fuel pressure regulator valve on it in most cases with spider injectors it can cause problems hard starts or no starts no resistence for the fuel to build up pressuere3 and an oring kit
spend the extra cash get the new and improved style

PLEASE HELP!!!! I have read the GM Bullitin that has been posted repeatedly throughout this forum. There have only been vague references to the NEW STYLE spider assembly installation. I have one in hand, and desperately want to install it, but it did not come with instructions to tell me where each line goes. The new style is somewhat different from the old one. I really need this answer. I keep getting the runaround from the people at GM and AUS Injectors. please do not respond with "just put the new one in the same way the old one was connected". I would not be asking for help if the old one was connected properly in the first place. I need some specific direction here....thanks in advance.
