I too have stickers on most of my tool boxes.
Have been a small engine mechanic for the last 45 years.
I have accumulated lots.
Unit comes in for repair I pull off the last repair guy's sticker and put my own onto it.
All stickers then end up on my tool box.
A small sample
Not wanting to high jack Wilcoy02's post on fuse box challenges I've started a new one.
Wanting to put a new fuse box into my GL1100 as the old one is all melted.
I too have done a lot of searching.
Working as a John Deere technician for the last 20 years I've seen a lot of electrical wiring...
I'm thinking that you would want to make sure the main tank
is close being empty before opening up the extra petcock.
Head pressure might cause the lower tanks to leak fuel out tank vents/filler caps.
