Wow Derek...this will most likely be a very helpful diagram, to the guys (just makes my head hurt to look at HAHA) I will show them this and get back to you though. This is really a great forum for these RVs! Thank you again, I feel like this will be a huge help to my mechanically inclined people! The mechanic said the whole metal part of the line was rusted, including where it went in to the tank and said we would have to replace the whole thing...there was really no discussion of just replacing the line (I assumed this was just a safety issue since it's the gas tank?) But this is a pretty fancy shop that does mostly high end classic cars, you could eat off the floor in there! I'm waiting to hear back from an rv mechanic who may have some more economical suggestions...stay tuned. The new tank isnt too bad but he said it will be like 4 or 5 hours labor and like I said, our plan was to smog it and sell it before finding all this out. In California you have to have a current smog cert to sell.
