The refill can stir up sediment in their tank that winds up in your tank.
--------------- Clip ---------------------
All underground tanks have condensation in them.
There are extremes where the water content gets so high that additives are
introduced into the tanks so the fuel is usable.
I've had TOO WET gasoline a few times and the first symptom is a backfiring
engine and very low horsepower.
It's not a bad idea to always carry a can of moisture dispersant. Products
recommended like Heat and Berrymans B12 have both worked for me.
------------------------------------------
You'll never get the crud out of your tank through the fuel outlet tube (it
has a filter sock).
The way I've gotten crystals and lumps of crud out of my tank was to put a
1/2" hose down through the fill neck with a weight (solder wrapped end) and
put 3 pounds pressure on the fuel outlet tube. I was surprised how much
debris I got out.
The tank always holds 1.5 Gallons of fuel so the van needs to be jacked up
on the left front about 8" to get all the fuel to a location that the 1/2"
hose can capture it.
You can keep straining the fuel that comes out and keep processing it back
through while tapping on the tank or banging it with a rubber hammer to get
other debris to move past the tank baffles.

Hi Volks,
Rust in the tank is not the only possible source of contamination.
On our way to EveryBus 2002 our group gassed up at the Citgo in Depew N.Y.
and
two of the buses were at the side of the road within an hour due to plugged
filters. My westfakia developed a vapour lock which was cleared by
dis-assembling it, Dad's vanagon pump died outright and was replaced with a
$100 ford pump and filter from a NAPA outlet in Bath N.Y.
Moral of the story: If the station is getting a refill from a tanker... find
a
different station. The refill can stir up sediment in their tank that winds
up
in your tank.
Happy trails,
