Bruce.. how close is the 3 bar MAP to the intake and where is the nipple feeding it. My concern stems from alcohol getting blown into the motor finding its way into your MAP and damaging it. If it can be mounted higher than the intake, probably not an issue.
Also if you can think of some idea to make a filter or liquid/separator so the MAP stays clean.. Having a few feet of line between the engine and MAP has worked out 100% so far, but I have one documented case on a non-Buick app whereby the MAP got hit.
Ohh.. Metco made a 7 gallon plastic fuel cell that fit in the spare tire wheel well now that your car is an addict :biggrin:
