How to tell which Super Yank you have
a little help?!? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Yank puts a sticker on it saying what it was. If the sticker is off there is no to tell from a visual inspection of the housing since the difference between the SY 3500 (most common, especailly for a C5) and SY 4000 is the blade angle on the pump.
