Pressure Damper problem??

[metr0p0lis1927]

while replacing cracked vacuum hoses in my engine bay I pulled the vac line off the fuel pressure damper and when I did, I noticed it was wet , not the damper itself , the vacuum hose. As in it was wet with gasoline, so I blew it out (the damper which was apparently full) and reattached the hose and started the car for a few minutes, then shut it off and checked the damper again which was once again full of fuel .

my questions are :
1) is this normal?
2) if not , does this mean that the internal diaphragm is shot and I need to replace the damper ?
3) is this dangerous?

1. no
2. yes
3. possibly, you will suffer performance wise as well as emissions.

Sounds like a bad damper diaphragm to me, but the best way to test itis to use a hand operated vacuum pump and attach it to the damper. If it holds a vacuum it should be okay, nut if the vacuum bleeds off, it's time for a new one.
