1tuffram, I purchased my Kerosun battery operated siphon (pump) as an accessory at the same time I purchased my Kerosun, kerosene heater, some twenty years ago. The standard, bulb operated siphon worked/works so-so, whereas the battery operated unit works extremely well!
Big White Beast, the cost when I purchased my 5-gallon can of Amalgamated DFA was $90. total... $50. for the product, $40. shipping (ground UPS). If I'm not mistaken, the shipping charge is an average... I believe the $40. price holds true regardless of where it's shipped (in the lower 48).
