Thanks Markus.
You are the man!

Markus,
You don't happen to have a picture of the back side of a Euro Gas Tank from a SEC Do you?

My tank is really different than what that schematic shows for the vent line. on mine there is one small vent line exiting the top cent of the tank and it 90]sto the rear and then 90's down behind the protective trunk wall(I haven't removed that yet) to see if there is a connection to the vent line behind that wall I do know that vent line exits through the sheet metal under the car......I think.

Is this any different? This is the file for the 500 series, the other ones I posted were for the 560 series, didn't realize they might be different....

That looks more like it.
Thanks.
My Indy said that the Euro tanks are different than the US ones because they had this vent line and that is what my tank has. I'll take the trunk panel off and see just where that sucker goes.

Actually mine comes from the top center and loops (2 90's) down the center of the back of the tank....Don't have the foggiest idea where it goes from there...yet! I could have that one too for asll I know. But if I have to remove the tank it's not so daunting a project now, But I'm betting that it's the seals around the sender and maybe the feed, return. and vent lines that is allowing the loos of pressure. hopefully not the filler neck joint to the tank.

My 1980 has a vent line that exits the bottom of the car and used to end in a check valve and a cone shaped end. That got lost probably diving over a snow drift. However the line that feeds it CANNOT be from the bottom of the tank or the tank would drain.

Yep I realize that the vent cannot be from the bottom of the tank, so this line must travel through the body sheet metal and exit where the vent line is connected. Yes I do realize that there is a feed line (big one, and a return line(small one) and the vent line. My vent line is hooked up to a vent valve and that line goes to the Charcoal canister.
What I don't know yet is IF the vent line from the top of the tank is connected to the vent line under the car via a hose connection, or if it is a single hard line to the connection under the car, (which is what I suspect).

Hey guys. I bought my SEC a couple of months ago and gas wasn't great. I mean, I thought it was partly because of the V8. But majority of it was because the fuel distributor was damaged. I replaced it with a new one a little after I got my subs (and amp, obviously) and noticed that gas became a lot better from what it used to be. But not necessarily great. The reason why I emphasize the AMP along with my subs, is because the amp is normally drilled onto the back of the backseats. That being said, I JUST found out the gas tanks on SECs are behind the backseats and not under the cars. That explains so much why gas milage isn't so great! And my car always reeks of gas whenever I load it. I never really noticed wet spots in my trunk, though. Nor does it smell after a while. Would you guys recommend getting a new tank or is this an easy fix?
