Ian C Posted April 3, 2005 Share Posted April 3, 2005 The sequential system on the Supra can seem very intimidating with it's mess of hoses and pipes, and these hoses and pipes are the main cause of problems when they age and split or fall off. When you are trying to track down problems with the sequential system you'll need to know what all these hoses do. Here is a pictorial guide as to what plumbing goes where, and also some of the other hoses scattered around the engine bay. -Ian Link to comment Share on other sites More sharing options...
