It all started at 0700 this morning when I filled my car up with gas at the base service station. I was getting ready to head up the California coast to visit my mom, and wouldn't you know it, I had sprung a leak. It looks as if it's coming from the top/upper area and the leak has stopped after dumping about a half gallon of fuel.

Questions:
1. Anyone know of the most common leak locations?

2. Any particularly reputable mechanics in San Diego? (I'm pressed for time otherwise I'd do it all myself)

3. Is there a racing fuel cell made for the 928? Contact info?

4. What can I expect to pay for a fuel cell replacement? Assuming the worst (including replacing fouled injectos).

All help is appreciated, Happy Independence Day

I assume you think you sprung a fuel tank leak. This is a common problem with older 928s.
No need to replace the fuel tank.

There is a hose that connects the filler tube portion of the the fuel tank to the top of the fuel tank. When this "breather hose" gets old and cracks, it will leak when fueling as the level nears full. As long as your filling leak has stopped and all the fuel has evaporated, you are OK to drive if you keep the level lower than where it spills out.

You need a breather hose P/N 928.201.194.03. The fuel tank needs to be pulled down for access to replace the hose. Start the job with as little fuel in the tank as possible, because you must remove the fuel line at the bottom rear of the tank.

Thanks Rich, I'll get that part on order and start burning down the fuel in the tank. I went through my manuals and came to a similar idea, with any luck at all we're both right.
