DHD,
Going on 7 years on the pump, no problems. Just replaced the original "D" batteries for the pump in November 09.
I think it is the best solution. I use the pump year round it makes the entire fuel process very easy.
Sounds like the solution.
Wow! 7 years on the original "D" batteries, thats unbelievable.
In the link you provided in your earlier thread:
American Wickョ Kerosene Battery Operated Syphon Pump (S175) - Kerosene Heater Wicks & Accessories - Ace Hardware
Do you think that pump maybe a little different than your "D" battery pump that you bought 7 years ago ?
I noticed under Product detail it states that pump requires two "AA" batteries.
Those smaller "AA" batteries probably wouldn't last 7 years like your "D" battery unit.
I wonder if it pumps less fuel per minute than your "D" battery unit ?
Maybe a "D" battery unit is still be available ?
In the "AA" battery unit it states 1.5 gallons a minute.
Thats 3.33333 minutes to empty a 5 gallon can of fuel,
that seems faster than what I could empty the 5 gallon can, via gravity feed thru the vented nozzle.
So even if it wasn't as fast as your Kerosene Pump, it seems it would be better than what I have now.
Still, I may look around for a "D" battery unit like yours.
