I have a few thoughts for you KyleQ. First of all, you're right to be skeptical of such a low budget build, heck I bought them and I'm skeptical, all mine came with the orings attached and the copper in the bag next to it. I know what would happen if those bags were somehow scratched or damaged in shipping/packing...yep the copper would go missing. I'm most concerned about how in your pictures the pintle is exposed...did these not come with covers for the pintle and inlet? They SHOULD have, mine did. All mine were Stanadyne D code, but they are probably reman to BB spec. Your best recourse is to have these injectors pop tested, you don't know what you have until you test it. The only thing you could really complain about at a price like this is if the injectors were not actually reman but instead just used and had the dirt cleaned off and shipped to you. The other worry would be if the pintle were shipped "naked" as it were, that is a very bad practice and most fuel injection and turbo shops frown on it and are obsessively cautious about keeping the pintle from being beaten up and dirt from getting in the inlet. If the reman wor was a) actually done and b) damage did not occur during shipping, brands, appearance, and other things are irrelevant IMO. Also know that Lucas/CAV and Delphi are all owned by United Technologies these days as far as I know, so it might be splitting hair to say they were different brands. Basically before I put any injectors in my truck no matter how much I like or dislike the vendor I will be pop testing and want them to be at 2000 psi +- 200 and for best performance they should all be within 50 psi of each other. 100-200 psi variance is acceptable but will net you a rougher running engine and may have an effect, however slight on injection timing and fuel economy.
