Tonight I just started up my LT4 (25K miles) that has been sitting in storage since last November. While warming up I used a bright light and checked everything for rodent problems (mice- none this year!) and leaks. At the back end of the left fuel rail I found gas leaking from what I believe is the fuel pressure regulator. It has a vacuum line coming in one end and fuel lines coming in the other side.

As the engine warmed up the fuel stopped leaking. The leak appeared to come from the regulator body at the center of the assembly and not from one of the fittings.

Has anyone else experienced a leak in this area and does anyone have any tips before I begin disassembly and replacement?

Yes, they have been known to leak with age.
Even though you have very low miles, the car is still 15 years old.

I bought one at Zip Corvette Parts (haven't installed it yet).

Thanks for the link. One more question, did the small oring seals come with the new fuel pressure regular?

Yes, the 0-ring comes with the regulator.
