You guys amaze me, cluster removal question

[troutin55]

I sit behind a computer all day, and I probably spend way too much time trolling on this site. The stuff I see you guys do absolutely blows me away. I've had my 66 C10 for about 7 months, and I have a few projects in mind. My next project is refreshing my gauge cluster, and add a tach. After many hours reading over Classic Industries site and this site on how to do it, I decided last night to give a shot. I can't even get past step 1!! How the he!! do you remove the oil pressure line?!?!? Looks like you unscrew it from the cluster, but I can't get my fingers back there! Pretty frustrated and a bit worried that I'm not cut out for this.
