    85 C10 Gas Tank Removal

    I just bought my 85 C10 with a 305/SM465 2wd about 2 weeks back. It has a pretty nasty fuel leak at the front of the tank. I have a replacement but Im not sure how I remove the tank itself. It appears to have a shield of some sort that runs from the top of the out-side of the truck that goes down under the tank and bolts to the frame. Do I have to remove this shield or do I have to take the bed off to do this? Are there bolts above that hold the shield in place? I havent had much time to look due to work but Im going to change it this weekend.

    Thanks,

    Tony

    Best way I found on my 85 is to unbolt the tank support brackets from the frame and drop the tank and all together.

    When I had to replace the fuel pump on my 87 w/TBI 305, I had to drop my tank.

    The flexible lines above the tank were too short to allow me to drop it enough to get at them. There also wasn't enough room to get at the sending unit with just the bed off, had to also drop tank.

    USE LOTS OF PENETRATING OIL

    It must vary a lot from truck to truck and from tank to tank. Many people have said that they have just dropped tanks with no problem, while others, myself included, have had to remove beds as well.

    It should become more clear when you get in to take a better look.

    Good luck.

    Yeah, I took it off this weekend. It only took me about 4 hrs of messing with it to change the tank. The hoses are far too short and I spent a good deal of time hooking them back up. When I get my new sending unit, Im going to make these hoses much longer and tie them up out of the way so I dont have to go through the hassle if I have to remove the tank again.
