System Looses Pressure
I have a 1992 RS camaro with TBI of course. When I check the fuel pressure with the engine running it is normal. After shutting the engine off pressure slowly drops until there is none. What are the possible causes? Isn't the system supposed to stay pressured up.

Nope, fuel pressure will bleed off through the Fuel Pump (there are no one way check valves as far as I know). Slow pressure drop is perfectly normal. As long as you are getting 11 to 14 PSI with engine running you should be ok for stock setup.
