Anyone bought an ac delco or "delphi" pump off ebay? If so, what has your experience been with them. No warranty? Buying a pump for a '98 olds bravada, dealershop wants $400+ for one. Ebay the way? Thanks

 

stuff like that is hit or miss on eBay they could be authentic by which you found a great deal! or it could be a cheap pump being sold as AC Delco, Delphi or Walbro, so you need to be careful.. remember if its looks too good to be true it probably is

 

Ditto! If you can get pics of actual part #'s stamped into the part that might be a help. Then at least if it's not what it says it is you have recourse.
