TXBILL,

I should have more specific, I meant fuel oil or Diesel fuel. You said you filled the new filter with Diesel fuel from the old filter. The problem is that the fuel from the old filter may have dirt in it and you are pouring that dirt into the new filter. It might be OK if you made sure not to get any of the fuel oil from the old filter into the center hole of the new filter, but I would rather use the hand pump to fill the new filter.
