Cant get lines off of the fuel filter
 

I've got the metal removal tool, I put it in place but the lines don't budge.
I have been messing with this for 3 hours.
And I swear I have the hacksaw in my left hand as a last resort.

I've read several write-ups on how to do this.

Anyone have any tips for me?



Thanks,

Nevermind

I got it.


I didn't realize once I got the tool into postion I had to pull the line.
I kept pushing the tool into the line.


BTW my rough idle is gone :)

There are two filter line sizes...3/8" and 5/16"...are running change on the production line.

fuel filter
 

Picked up a filter, and now I see it might be the wrong one? Didnt know about 2 dif fuel line sizes. guess I have a 50/50 shot at having the right one tho.

I think the Flex Fuel motors use the part (1038) with the larger diameter (3/8") fuel lines. The other part # (can't remember off the top of my head) is for smaller diameter lines.

Fuel filter for the 5.4l according to the owners manual is the Motorcraft FG-986-B.
It is the same for all three engines 4.2L, 4.6L or 5.4L offered in the '08
