I am trying to decide my best course of action. I have a 1996 PI Crown Victoria set up with GFI for Bi-fuel and the Compuvalve is sitting right under the hood. My nose tells me that this lovely device is leaking. I am fairly handy, but have never pulled one of these apart. From what I can tell the source of the leak seems to center on one of the visible fuel injectors and I assume it would probably be the O-ring. I have seen people write about rebuilding these things on their own and cleaning things out, but not sure I want to take the risk of doing something wrong and costing myself thousands in replacement cost for this nasty little contraption.
