Before you go any further, a Question.
Does your car still have the Trap Oxidizer in the exhaust? It's a football shaped metal can behind the turbo before the exhaust downpipe.
If so, that needs to be removed as they are prone to plugging and the factory will replace it under a warranty recall, actually they will install a CAT device under the car and bypass the Trap.
The symptoms of sluggish engine can also be attributed to a sticky wastegate flapper in the turbo. And a plugged fuel filter.
The hoses are available through Fastlane, you probably need to call Phil and describe the hoses, the clips are necessary to prevent the injector lines from vibrating against each other and the brackets and wearing through, a common problem in this model with the thin metal lines.
