Drive this thing until hot and when
you shut it off, open the hood and find the vacuum hose that goes to
the fuel pressure regulator. It will be on the drivers side of engine
on the fuel rail. It's a little round vacuum diaphragm with a hose to
it. Pull this hose off and see if gas leaks out the little nipple of
the regulator. I'll bet it's leaking and what is happening is that it's
flooding out the engine after it's off for an hour or more.
fairly easy to replace since they are on the outside of plenum. Just be
VERY careful as to look at the new one before removing the old one.
Check location of the retainer clip, if it is not on right the
regulator can pop out and you will have a major leak!!! Also be sure to
remove the old O-ring and screen from the rail, they tend to stay in
there when you pull the regulator off. You won't be able to get new one
in if old parts are left in the rail.
