Want to sell a set of 60 lb injectors that I purchased from DC performance 2 months ago. Just can't get them to work the way I had wanted. Sale price $500.00. Purchase price was $900.00. Perhaps 20 miles use on these although I did use the "O" rings on my old injectors. New "o" rings should cost you $3.00 to $4.00 each. PM me if interested.
