Has anyone tried one of the cheap, new SAI pumps on ebay? seems prices have come down a ton to where buying a used one does not make sense. Any opinions are appreciated.

 

Now that you mentioned it, I checked Ebay myself. Thanks for the info.

They indeed have gone down in price. I noticed the cheaper Ebay ones are designated for 1999 to 2002. Just wondering if the SAI pumps are different for the 4.0 and 4.6-lter engines. Or if they are interchangeable?
