I was looking on my 85 GT 2.8 today and found a loose ground strap coming from the engine. Its on the side toward the passenger compartment, near the valve cover. Also, there was a rubber hose someone cut that connects to a metal tube that runs along the firewall from midway to the drivers side. Dont know what that is either. Any clues? Its a 2.8 auto. I didnt get to change the fuel filter like I wanted today...too much to do. Oh...how do you bleed the fuel system to change the filter w/o a pressure tester w/ a bleeder valve?

The ground strap is probably the one that goes to where the decklid hinge is mounted. I usually depressurize the fuel system to change the fuel filter by removing the fuel pump fuse, and letting the engine run until it runs out of fuel. No idea on the vacuum hose, the 2.8L has about 6.78 miles of vacuum lines.

Thanks!! I appreciate it.

The hose use to hook up to the air cleaner. It is part of a recell where they removed the connection. I am not sure of the specifics to verify what they did, But you should be able to remove it if the recall was done.

As for ground straps, You should have 2 of them. The one you have that is loose attaches to the decklid hinge bracket. There should be another one going from a bolt on the transaxle/engine and mounts to the frame under the air cleaner assembly on the driver side. Make sure all your ground straps are present and clean. Dirty or broken ground straps can cause intermittent electrical and sensor problems.

I left the deck hinge ground strap on, after doping up the bolts with di-electric grease. I added a ground from the bellhousing bolts to the frame.

Having 2 engine grounds is good insurance.
