Pressure release valve for fuel system

[crd8481]

I own a 1990 Reatta convertible.  I need to replace the fuel filter.  I don't know where to release the fuel pressure before replacing the filter.  Can somebody tell me exactly where to find the pressure relief valve for the fuel system?

It is on the fuel rail on top of the engine. You should see it protruding thru the engine cover shroud above the letter "N", or pull the shroud off to get better access. There should be a small cap you need to unscrew.
