Great write up. Just want to add what I found with my tank.

Perhaps looks like a common failure point?

Background.
I had been chasing a gas fume issue for ages..checked all the usual culprits first..charcoal canister ..Y fitting etc...

I narrowed it down to the back of the car when I noticed the black cap/lid was loose that sits over the fuel sender fitting in the rear hatch area. After I secured that the smell was decreased dramatically INSIDE the car...but it was still there.

I had dreaded dropping the fuel tank but today went at it with the aid of this write up. My crossover vent hose was in great shape and there wasn't any outwards signs of a fuel leak on the tank. As I cleaned it I found what you see below, a small crack in the very upper corner part of the tank. Almost EXACTLY where Dwayne found his.

Dwaynes is the one with the green arrow on it.

Congrats.
Many little things in the 928 drive people nuts. It is finding them and fixing them that gives people great pleasures.

Quick question, i dont plan on jacking the car up on 4 jack stands, i am planning on putting the rear on ramps. It should give enough clearance.

My question is.... is it really necessary to remove the rear wheel by the fuel cap?


Let me know!

There is a vent line from the top right side of the tank that goes THROUGH the body rail to the filler neck. This needs to be fed through the body hole as the tank is lowered, so it would be difficult if the wheel is there. I removed my tank with the rear of the car on stands as high as I could jack it on the cross member, and the front end still on its wheels.

I can see that being a pain.. Did you place the jacks on the designated areas? I use to put them on 2 points close by the cross member. I believe it's where the shocks meet.

I think I used the designated jacking points for the stands, but jacked on the centre of the cross member. Dont think it matters too much, but it needs to be higher than average jacking - wheels clear of the ground around 6" from memory, otherwise the tank wont come clear.

Any idea what is causing this damage? Does anyone think the tank is rubbing at this point, too much stress or a manufacturing error on some tanks?

Hi Tomkat, hopefully some other members can help but i have a feeling that i have the same issue as my tank is wet all the time(pleased that i haven't died yet). I will be inspecting the areas around and see if anything is wrong where it sits. But mostly likely its just the pressure and how old they are.
