I literally did this last night, and I just saw your pic while checking on steps to drop tank one more time. Great minds think alike! Haha.I concocted this thing to help stabilize the gas skid/tank when I lowered mine, just used some standard wire shelving I had lying around and unbolted the saddle and bolted it back on top of the shelf wiring. Worked pretty well!
Just to parrot the above, try to get the tank as empty as possible and lower it SLOWLY. Those rollover valves are easy to break...

Removing and replacing the retaining ring is easy with a big strap wrench. Be aware that most strap wrenches are not big enough but but they're available. I found mine in the plumbing dept. of Home Depot, they were too small in the tool department.I feel there are two things that could possibly be a PIA about replacing the fuel pump:
1. Dropping the tank.
2. Removing the fuel pump retaining ring.
I’m pretty sure that won’t fit 05,06. I purchased one before I did my 06 and it wouldn’t fit. The 05 and 06 uses a flat metal ring. I used a punch and hammer.
There is some degree of thought that fuel pumps that are about to go out tend to do it when a tank is just filled.Fuel pump went out in my suburban years back....I had just filled the 40 gallon tank Talk about SUCK!
