The only (repeat ONLY) thing I've purchased from Mylex is new Delphi's. The reason is, no one else had any at the time and I wanted to get my Moose injectors under the EDM machine. I bought a new set from them and shipped them directly to Mel for Moose mods.
Man, I hate to hear about all the trouble you've had with those injectors. Here's to hoping the new Delphi's all will pop open when they should, have an excellent pattern, and give you many trouble free miles.
