Mike's on the right track timing wise. I wonder if there was a special tank for '85.
Ooooh, I wonder if there was a CA only tank. Yours is a federal (ie 49 state) car? I wonder if you put a CA tank in and maybe its not exactly the same shape as the federal model. Otherwise maybe a wire got pinched or something. -Curt Date: Sun, 23 Jun 2013 12:54:54 -0400 From: Michael Canfield <slozuk...@gmail.com> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] I give up!

Only thing I can come up with would be if the tank is supposed to be grounded to the chassis and maybe the coating on the new tank is preventing a good ground? Does the circuit have it's own ground or is it depending on a connection between the sender and the tank and the tank to the chassis? Maybe........ Mike On Jun 23, 2013 12:42 PM, "G. M.
