Well, in this case I have to beg to differ with what Dale posted. All of the GM cars of that time that have the filler neck in the bumper require a non-vented cap. The reason that the EC & wagons have a vented cap is because the filler neck is on the side and the tank does not have a vent line. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Larry Shouse Sent: Sunday, February 19, 2006 8:52 PM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] Gas tank ... John, What you are saying makes sense to me concerning spills, but it's not in line with what Dale posted about what the Chevrolet book says, which said "all take the same vented cap (#3843698)". Not pointing fingers at anyone here, just curious... Larry Shouse _____________________________________________________________ Netscape. just the net you need
