Finally....
....figured I'd update this thread I started a while back. I actually swapped out the tank and all of the innards in late August at CDan's house with the help of CDan and Mrs. CDan.
Some interesting things:
1. Rust sucks. Got to replace more bolts on this operation. Soon, I won't have any rusted bolts. I must have over $600 in new OEM Toyota nuts and bolts on my rig.
2. It was nasty in the tank after 12 years of use.
3. Dan figured this would be a good time to actually test the theory that the "low gas" indicator light comes on when there is 5 gals. left in the tank. Since we started with a completely new and empty tank, we put a 5 gallon jug of petrol into the thing and lo and behold the light went off exactly as Dan finished pouring in the 5 gallon jug thereby confirming the "low gas" light indicator. When that goes on, you've got 5 gallons left (as long as your tank is still in OEM shape....

)
4. Fuel pumps are expensive.
5. I really need to fab (or have fabbed for me) a gas tank skid plate. At the rate I wheel, I'll need a new one after every Rubithon.
6. While you have the fuel pump bracket out, it would be a good time to either sheath or ziptie (or both) the wires that run to the fuel pump out of the way of harm so you don't run into the issues NorCalDoug had in Death Valley a few years back or the same problem I had on my way home from the Rubithon this past summer--basically the gray wire running from the top of the bracket to the fuel pump chafes on the sharp edge of the fuel pump bracket and shorts out thereby rendering your cruiser un-moveable. I grabbed a bit of commercial aircraft grade teflon sheathing/tape and wound the wires with that and then ziptied them out of the way. Should be a good solution.
In any event, onto the pics. The wrenching on this was pretty straight forward. Nothing really interesting whatsoever.
Best regards.
