Decided I couldn't wait- so started to work the frozen bolt on the fuel filter. It finally did loosen- using the line wrench. It never would turn without muscle until it was completely off the filter. When the filter was completely off- still could not hand turn the fuel line bolt.
Ran into another problem- could not get the filter off the strap. The bolt that holds the strap was also frozen an unaccessable. It also started to pour rain and I was outside. I decided to lube the outside of the old filter, and then turned the 20mm bolt for about 10 minutes and it finally came out.
Couldn't find my never seize, so I used wheel bearing grease on the threads of the new filter. Also greased up the outside of the filter so I could slip it easily on through the strap. Installed the new filter, started it up- checked for leaks- all is well.
I think I would have stripped or bent the fuel line and/or fuel line bolt if it were not for the16mm line wrench. Also- the fuel filter bolt/ nut is 20mm for those who don't want to use an adjustable wrench.
Finally- I have a new lube point for the Bravada and Bonny- the point where the fuel line goes into the flared threaded nut. I will be spraying that with teflon or something every few months. That being near seized really added an additional worry.
