A year + ago, I was buying a 2WD gas tank.  There was at least
one other source--in Seattle, I think.  Similar price.  Same
tank.  There is only one source of tanks now--Taiwan--even
though the labelling says Brazil, I think.

You might search the archives to find the troubles I had.
The vent was not correctly soldered where it exits the tank.
Bus Depot checked and at first thought that ALL the tanks
they had were that way.  Then they called and said they had
found (at least) one that was correct, which they sent to
me.

The posts would be around April 30, 2009.  I posted some pictures
which are still available at

and

Bus Depot went out of their way to see and fix the problem.  They
are our friends!

I wouldn't replace the sending unit if it works.  But be careful
pulling it out and putting it in, 'cause you can ruin it and you
don't want to drop the new tank....
