It is frequent practices that shops think those supports under the tank
are suitable for lifting the van with the lift. Of course the tank get
damaged. Another possibility is that there is a problem with the tank
venting and the fuel pump suction is collapsing the tank. The tube at
the bottom of the carbon canister. It is common for the screen in the
canister to rust out allowing the fine carbon to fill the tube and clog
it. This is the only way air is supposed to enter the tank as the fuel
is used. Also, make sure the valve for it, (The black valve near the air
filter) is getting the proper vacuum signal. You should hear it click
when the throttle is opened.

Subject: Gas tank dents

I was under my '87 the other day it looks like the tank is pushed up
on one side. It's not even touching the support strap on the drivers
side.
Anyone ever pulled this type of dent before?
