In the attached picture, you can see that I'm having trouble getting the bolt out to remove the thermostat. Is it safe to remove the fuel rail ( I think that's what it is) in order to get the bolt out? I don't want to mess anything up by moving it out of the way, like springs, or something else. m/n 1150D73HY and s/n 1B776243

When I did mine I did have to remove the rail...just far enough to get to the bolt.
Be sure to lubricate the o-rings before reinstalling the rail.

After looking a little closer, it looks like I can just remove the air hose going into the top of the fuel rail. Are there any special precautions? Do I need to bleed off the fuel pressure before removing? Do I have to do anything to get the pressure built back up after reinstalling?

I thought that pulling the rail was the simplest way to go. I think that's what the manual said but I do not have my manual at hand.
I used a little marine grease on the o-rings. The whole rail just eases back and comes off the stems to get to the stat.

I took your advice and pulled the fuel rail. Very simple. All responses are very much appreciated!

Don recommends DFI oil on the o-rings and is what I used when I changed thermostats on mine.

Yes, it was DFI oil and not grease that I used. Grease will likely work but the DFI oil is thinner. Sorry for the error.Don recommends DFI oil on the o-rings and is what I used when I changed thermostats on mine.

Definitely recommend DFI or Premium Plus OIL. Grease can become trapped in the injector (potentially).
