where is this info coming from??
The fuel pressure regulator uses vacuum to reduce fuel. at idle, there's more vacuum on the FPR, so it reduces fuel pressure slightly. under full throttle, vacuum drops and fuel pressure increases since the needed for fuel increases.
This question is much more suited to an engine forum rather than the B2/Explorer specific forum.
Ugg I was exactly opposite, I will go stand in the corner now.

Best way to check is with a fuel pressure gauge to determine if it's working correctly. If it's running OK, and no fuel is leaking through to the vacuum line, sounds like it working fine.
