How to drain and clean a VW Beetle fuel tank.

Dude, you're not dumb haha. Not everyone knows how to work on things and hey, we all started somewhere!
First off, that Beetle is effing sick!
1. Disconnect the wire that is plugged into the fuel level sending unit. (Wire that is plugged into the VDO sending unit located directly in the top of the tank.) It looks like your may actually twist and pull out?
2. Disconnect the small vent hose that is connected right below the filler cap.
3. Remove all 4 bolts that hold the tank itself down. (They are directly on top on each corner of the tank.)
4. Remove the gas cap.
5. This is the hardest part. Make sure you have a large catch can! I use a big oil drain pan from Wal-Mart.

They are around $10.
Get the car on jack stands so you have plenty of room underneath.
Look underneath the tank, you will see one or two hoses coming out towards the back of the tank.
Loosen the hose clamps or whatever is holding the hoses on and place the drain pan underneath.
Now, it's fun time! Get the hell out of the way and reach up and pull one hose off. Get your hand out of the way and wipe off any gas you gt on you quickly with a rag. The shit burns after a bit if you leave it on your skin so wiping it off is best!
Let it drain and keep and eye on the catch can.
When it get's about 75% full get the hose back on where it was and dump the can. Repeat until empty!
6. Remove the other hose attached to the bottom of the tank if there is one. Then remove the tank from the car!
