DO NOT run it anymore (not even 10 seconds) till you swap the reg. I'm assuming you have an OE type electromechanical type reg? Your parts house has a Wells VR 706 (iirc) electronic replacemnt reg (does not look identical to OE) and mrrandyj at aol dot com has an electronic version with an black cover that does look identical to the OE electromechanical ones for $29 to your door. Reportedly you can swap your current cover to an electronic parts house replacement reg but I ain't sure which one that is.
