Do you think it's safe...

To use an impact wrench on the HFCM filter cap? Somebody put that sucker on waaaay too tight.

I tried it with 120lbs. of pressure and that didn't work, even with long bursts. I'm going to crank the pressure up a bit.

It's easy enough to disconnect the fuel lines, electrical plugs, and unbolt it from the frame. Throw it in the bench vise to get it apart. While it's out clean it.

I got it off with 150 lbs. It was still hard to turn after it broke loose. The filter didn't come out with the cap, but it wasn't hard to remove. The fuel looked good, I cleaned everything up. This truck looks amazing underneath. Everything is in place just like it came from the factory. Under the hood as well.

Whenever I run into something fuel related that is a PIA to get apart i use a heat gun. Also works great on a part that you dont want to discolor/distort the surface on vs using a torch. Takes a bit longer but normally gets the job done.
