I'm trying to locate the fuel temp sensor, can anyone help? I think I've found it, but want to be certain. I think its at the front right hand-side of the engine. In the fuel line being held in with a green spring clip? This might seem like a silly question, but what is the tandem pump? I may know what it is, but just know it by a different name. I've only really worked on fords, so don't know all the Audi terminology. Any pics would be really useful too! Thanks guys and girls!
