Rot 911,
I ordered one of the pumps that you have experience with. It arrived this week and I tested it out and it worked great! However, I do have a question: inside that plastic bag containing the instruction sheet, there were about 10 white ribbon-like pieces of material that were about four inches in length. Do you know what the purpose is for these items? Nothing was mentioned on the instruction sheet.

Length of fuel line and a one way valved priming bulb
