ever tuned it up? sounds like its due. plugs, wires, fuel filter (if equipped), PCV, and an intake system cleaning should restore your fuel economy to where you want it.

If you are referring to the pickup screen tube size, it would be either a 3/4inch or a 5/8 inch Most rplacement pumps use the 3/4. If in doubt, buy the pump and pickup at the same time and get both of them in the same size.
