Tom, about that pump that runs off the exhaust cam, do ALL Testarossas have this pump? I see it in my parts manual...but info. is sketchy. |

Tom, I have an '87 U.S. version Testarossa. I'll have to borrow a camera for pics, not sure yet. I may just bUy a "generic" cannister and replace that thing. I wish I knew what the reasoning is behind it....why do I get a bad feeling about this? |

Jeff, exactly what model is your TR and is it US or Euro? I would love to see some pictures of what you are describing. |

Thanks Tom and Adam, I did some reading in the manuals and they only show a vacuum cannister that accumulates vacuum to operate the climate controls. And that vacuum is drawn from the left side intake plenum. NO PUMP ! The pump on my car appears new, and has an electrical wire going across the rear bumper to the area under the right rear fender. And here's the kicker, it is not hooked up to anything, just a terminal tucked into the wiring! It now looks to me like someone was doing a "band aid" job to create more vacuum rather than figure out the problem, which is likely in the dash or console area. Since my car is in pieces I'll have to wait until spring to find out. I would like to hear more information before I tear that pump out and put the proper cannister in. Plus I have to find a cannister first. This car has been, and I'm sure will be, a real head scratcher. |

Jeff...it looks to be the Vacuum reservoir for the A/C system. It should have a small hose from the engine to a one way valve and then into the canister. The larger hose runs to the push button system in the center console. |

Jeff, it sounds like you are describing the vacuum pump that is run off the back side of the left bank exhaust cam. This helps make vacuum for the brakes and climate control. |

Hate to be a pain, but what is the function of this pump? A hose goes out from the pump into a "t" fitting where it splits off, a small hose going to the left intake plenum, and a large hose heading towards the front of the car. Does this make vacuum to run the climate controls and whatever.....? I see a vacuum cannister or resevoir in the manuals, my car does not have one of these and I'm thinking it's missing in action? Please educate me on this. |

With my car in pieces for a 6 month detailing, I happened to notice a pump of some kind in the left-rear fender near the tail lights. What does this do? What ever it does, my car has a brand new one (about the only nice clean looking item in the engine bay) |
