Default Replacing gas tank filler neck gasket - Need advice please.

When I top off my gas tank it leaks around the filler neck gasket till I run the level down below it. I decided to replace the filler neck gasket and figured it to be a simple job (until I tried to remove the filler neck).

I can easily get to the lower bolts and the bolts going up around the side of the radius. When I get to the bolts around the top of the radius I can't get a screwdriver on them. Any suggestions how to get these bolts out would be appreciated. I sure hope I do not have to loosen and move the tank.
Thanks, Roy

I just put a new tank and filler neck in my 65 coupe. My tank was loose but in order to get to the upper neck bolts I stuck my small hand into the body, then lifted the tank up a bit to tilt the front of the tank towards me. That allowed me to get to those bolts.

It's a relative easy job if the tank isn't bolted in yet because you can move it around to gain better access to the neck bolts.

loosen the straps - you dont have to drop the tank, you just need to be able to rock it up a little.

the other issue that maybe you havent thought of is when you go to put those little bolts back in, you will be pointing straight down, and the bolts will fall right out of the socket. make sure you either have a magnet to keep the bolts in place, OR use a little rtv on the bolt heads. that will keep it in the socket long enought to get it in.

Thanks for the advice. I still have the spare tire tub out from doing the differential work recently. I'll loosen the straps ang give it a try.
Thanks again, Roy

I would use a little gas-resistant sealer on the gasket to prevent the leaks you are experiencing. Although I had a new tank and worked the filler neck flange over to get it as flat as possible I still had some weeping. I finally used two gaskets with Permatex between them, the tank and the filler flange. So good so far.

Good suggestion Dan (thanks), I'll use my favorite sealer, Permatex The Right Stuff.
