Default Ruptured Fuel Filter Line.Is it under Vacuum Pressure?

Does anybody knows if the line that goes from the Fuel Filter to the engine is under Vacuum? I just changed the Fuel Filter and noticed it was ruptured at the end...it came out fairly easy from the older filter...No leaks though !!!

Fuel pumps push fuel through the lines.

Thanks Tomboy...
Do you know if by having a rupture in the fuel line could contribute to the intermittent lost of power?

Thank you !
I changed coils and cables to Accel___ Spark plugs NGK-TRS RV-Power
The truck was running fine, but ever since I changed this_It has been getting an intermitent power failure...
I could be going 70 mph and next second down to no more than 40 mph...no more ! very scary on the highway !!!
What did I do wrong ?
Things I did to try to fix the problem: :
1-Changed Fuel Filter, notice the line from filter to engine is rupture_no leaks though.
2-Cleaned the IAC valve.
3-Cleaned the Mass Air Flow Sensor
4-Changed the PCV Valve_ It had a Motorcraft Brand in it.
5-Changed the Brake Booster Vacuum Gage thinking it could be a Vacuum leak.
6-I check for Vacuum leaks with Carb cleaner method...Nothing !
7- Changed the Fuel Pressure Regulator.
I sincerely would appreciate your help.
The lost of power is the same as the YoutubeURL

Default Re: Ruptured Fuel Filter Line.Is it under Vacuum Pressure?

Just finished installing new motorcraft spark plugs...No change.Two of the old ones(they were 3 month old) had oil at the electrode end...... Is raining here so I did the work inside the garage, and notice that the truck is running the same 'bad", but very"very" rich.
Any ideas....
Many thanks gentleman.
