I need to defuel the Allante, about 11 gallons.Does anyone know if I can fool a Cadillac into pumping the fuel out of the tank using the fuel pump without running the engine? I attached a hose to the fuel filter (engine side of filter) and placed the other end into an external gas can. I heard something about a fuel pump test connector somewhere in the engine compartment, urban legend?
Only a select few 95 cars had the test port. Why they still don't include it is beyond me.
If you are good with schematics and can figure out which relay is the fuel pump, you could enable it manually. No, I don't know. If you know someone with a high end scanner that can enable it through the PCM, that'* even better.
