Good photos! I've not looked inside of one, but I am sure that hose has to connect
with the outlet. And that's probably why, when you get the tank off, no gas drains
from the outlet.
I recently dropped the tank on my '88 Westy and the leak was coming from a broken
cross-over tube. The tank was in good condition, so I gave it a quick paint job and
re-installed it.
The condition of the tank will of course depend on where you live, the salt belt or
the southwest.
I would think you definitely need the screen. You could have a lot of crud in the
tank, but with the gas constantly sloshing around, it won't accumulate on the screen,
whereas a filter would clog.
Just my thoughts.

Subject: Gas Tank Restore
I have to drop the gas tank on my 87 to fix the typical leak when full. Since I'm
going to already have it out, I want to clean it up, paint it and put a liner in it so
I don't have to worry about it again for a while. A fellow list member suggested the
POR-15 sealer kit and the how-to instructions found at
http://www.ratwell.com/technical/FuelTankRestoration.html
However, when a local shop recently went to have it lined, they were told it couldn't
be done because of a screen inside the tank. Well I finaly got my hands on a doner to
do a little pre-investigation. I was suprised to see the screen was not something at
the outlet pipe but rather a round plastic thing in the bottom with a hose running
from it. I managed to take some pictures looking in from the sending guage hole and
posted them here.

Now I'm totally confused. The green hose comming off the screen is only about 6" long
and doesn't seem to go anywhere.
Is this hose supposed to somehow connect to the outlet pipe? Seems like this is the
only way to ensure the gas drawn out passed through the screen. Otherwise I don't see
a purpose for it?
Am I missing the rest of my hose and some sort of connection on the other end?
Is this screen really needed?
What about just putting in the liner and letting it cover the screen?
One option I considered if I don't use the screen is to install an inline filter
between the tank and the pump. Another list member noted that pre-pump filters can
cause problems if they get clogged such as vapor lock, fuel starvation and all sorts
of inconsistent running problems. I guess you could mitigate this by changing the
filter often.
Any insight appreciated. I'm not really sure where to go from here. I guess one
option if the tank itself isn't leaking is to replace the cross-over pipe and seals
and leave the actual tank for a later day. I'd much prefer to restore a good used
tank if possible than buy a new one. My understanding is the only new ones available
are made in China and is prone to rust quickly.
Thanks,
Mike
