Figured I'd pull the fuel tank and check it out- wouldn't want a bunch of rusty crud messing with my eventually rebuilt motor. Glad I did!

I thought it'd be a simple job, but the weather stripping-like sealant foam between the trunk and the tank was super nasty to deal with. It had me double- and triple-checking that I had removed all of the hold down clips/bolts, because it really held the tank down! I put a floor jack under the tank to try to break the adhesive grip, and nearly got both front wheels off the ground before seeing any play. Eventually a sacrificial box-cutter blade into the sticky and tar-like adhesive broke it free.

Here's the tank, removed. You can see remaining strips of the adhesive foam. There's no record in the car's history of any work that would require tank removal, so I guess that's the original stuff; it's a goopy mess that won't be fun to clean up.

I spent an hour or so rinsing and flushing w Simple Green. Lots of rusty material came out, so it'll need some work. My plan is to have the tank professionally flushed and coated, assuming no major flaws are revealed.

Here's the fuel outlet "filter". Hard to imagine this working properly- it looks like it must have been restricting the flow in a bad way. I guess that's why Porsche went to the swirl-pot design shortly after this gen...

Glad to check this off the list!
