My bet is the tank is damaged from lifting or vacuum collapse. After it
runs dry, you will need some extra to get the sump to fill. Part of the
design is that the return is dumped back to the pick up sump and it is
designed to keep fuel from splashing away from the inlet as the van moves,
goes uphill, etc. Once the sump is dry, you need extra fuel to fill it and
get the pump primed. You should also plan on a near future pump
replacement.

Subject: Ran out of gas; only took 13 gallons to fill

I ran out of gas today and it only took 13 gallons to fill it. What could
be going on here. The tank is a few years old. I don't remember having
problems back then, but I think the gauge is not so accurate on the low
end now. Could something internal to the tank be wrong? Pick-up tube? Does
anyone have a pic or drawing of what the inside of a tank looks like?

Thanks,
