Anyone work on cars here?

to relieve fuel pressure you pull the "fuel pump" fuse while the car is idling or just depress the schrader valve on the fuel rail when the car is off. or if you let the car set for an hour or so the fuel press will have bled off by then.

The fuel rail schrader can be a good methor of pressure release, depending on where it is located. Some manufactures try to bury the thing in the back amongst electrical cables and vacuum hoses, while some don't even suppy a test point, so you have to use a plumbling adapter from a test kit. Once again, watch that fuel spray.

Pinching off fuel lines works on a lot of cars and truck, where the maker was good enough to use rubber fuel line. Many of the GM products use metal lines, flare nuts, and small "o" rings.

It never hurts to drape a shop rag over the connection as it is loosened to absorb the escaping fuel.
