Hi Ian I read the responses to my original post and enjoyed them. My question is why the heck does a curcuit run thru the oil sensor at all....it must do something.....I thought the relay sent power thru it and it was bypassed by the computer for startup for a few seconds...and would kill the engine if pressure failed. Also....I found out a fuel filter for this thing costs over $40! Guess it has something to do with being a flex fuel engine ...or...the fact that it has 2 pipes going into the inlet, and maybe the thing circulates back to the tank from there and has a back pressure valve in the filter???? Thaniks for all the info...Thanks to everyone....Pete
