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,
