Got the tank in. It's from LMC. Couldn't have been easier. A slight clearance modification with the die grinder on one of the seatbelt holes.
I was concerned about how the filler neck was centered (or wasn't) in the opening. I thought about how to bend it, and finally after staring at it for awhile, I grabbed it and pulled down. It bent very easily.
I tried to install the filler neck rubber with the tank in place. Wrong move. I searched the site and got ideas, but I didn't have any luck.
After another round, I removed the tank and put the rubber in place. I lubed up the neck and the rubber with dish washing soap and put the jam to it.
It slid in so easy that I pushed the tank into the cab! Be careful trying this.
Glad I put that carpet in the back corners. It looks much better in place. I put edge guard on the tank, but it wasn't needed.
Fuel line and gauge wire installed.
Had the cardboard cover since I bought the truck. I didn't like the way it fit originally, so I never used it.
I looked it over and saw how I could make it fit better. Heavy staples on the folded edges and it fit great! Looks good too!
