Feeling a little bored and destructive this Sunday afternoon, I
decided to cut into my old fuel tank.  It was pretty rusty and had
some pin hole leaks in it.  Here's some pictures if you ever wondered
what the inside of your fuel tank looks like:

Top of picture is front of van.  Line to engine on right, line from

With screen removed, there's a resevoir that the fuel must get down into:

Upper left side of tank.  Rust or fuel reacting with the weld?  That's
the vent to the expansion tanks.  Fuel sender on lower left:
