You will need to drop the tank and repair the cross over tube and
grommets. Also plan on replacing the seals at the top of the expansion
tanks in each wheel well. You also need to check the charcoal canister and
related tubing and the valve. After sealing things up a non functioning or
clogged vapor recovery system can collapse the tank. If this van is new to
you consider that the upper leaks have been there for a while which also
mean that road debris and water have gotten in. Future FI repairs and a
rusted tank are on the way.

Subject: major fuel leak

Several issues tonight, but I'll post them separately in the interest
of keeping the thread topics focused.

Filled up my van for the first time since I've had it -- it was just
above the reserve mark when I got it, and I put 5 gallons in it to
get home that night.

Today I filled it up full.  But, just as the pump shut off, I heard
splashing under the van.  Looked underneath, and a significant amount
of gasoline was spilling out of the center "valley" of the tank.
Probably at least a pint, maybe more, went onto the ground.

Looking at the Bentley illustrations, it appears that the most likely
suspect that could leak that amount of fuel that quickly would be the
fuel sender opening.  That's assuming, of course, that the tank does
not have a completely open rust hole in the top.

What's likely here?  Anyone dealt with anything like this?  I guess
I'm going to have to drop the tank, too bad it's full to the brim of
fuel now.
