excessive pressure in the gas tank?

Porsche issued a technical bulletin in this issue. Apparently, there are a couple of hoses in the fuel tank that get in the way and restrict the fuel flap from opening completely. The fix is to use zip ties to move the hoses out of the way. IIRC the procedure involves removing the fuel sending unit.

Thanks Thom, Going to meet him later today at the gas station and see if I can get more insight into how it is acting. He is a great guy and good neighbor, but is a retired pediatrician and it seems that babies and Porsches are not enough alike to help him figure out some of these problems so I help out when I can.
Any idea how I could access the tech bulletin for more info?

The TSB title is Fuel Tank Hose Modification. If you're a Contributing Member in the Renntech forum, you can download it from the DIY section. Not sure if I can download the and share because of copyright limitations.

PS: Picture of hoses zip tied in place

Thanks Thom, I will have to join renntech and check it out. Who knows, mine may do it someday. Still not clear on what is actually happening to cause the problem, but maybe the TSB will explain in detail how it is malfuncting. Thanks again
