I haven't. I was able to get under the hood for a bit. Had it on the lift and quite a few little pop up issues. Had a small fuel leak from the feed off the tank. Just such a pain in the ass to drop the tank, especially with fuel in it and not damaging really any of the lines, or wires. Typically I work on the truck my self. But sometimes I need a extra hand- in this case manipulate the fuel cell around ( gmc syclone) I could probably drop a typhoon tank in half the time and I believe it can be done from the rear of the vehicle. Syclone, it's either UP in the air, or bed OFF. Haven't seen any other way.
With the 1 fuel leak, came a lower trans hard line leak also. There is absolutely a order of operations to install everything back. I was able to address the leak with a crows foot style attachment for a ratchet. I didn't have any other solution to get a wrench/line wrench in there. Maybe some one has a future tip? I didn't want to remove the top line, no way. And I have 2 small coolant leaks I found pop up, or 3. 2 of which are at hose locations. One off the heater core ( lower line) the hose must be dry and clamp dug in. Have a small weep at the rad hose off the stat and one almost right under it. I'm looking for a factory style rad hose.
My map reading was @ 88? Key on engine off. Was told it's on the low side. Ultimately I need to run the truck a little bit longer, get it up to temperature and figure it out from there. Also maybe drive it. I just had trans done ( couple years ago) but it's brand spanking new and I had a lot of the underside of the truck apart and out.
