Went to NAPA today to pick up the oil pump and pickup screen that I ordered for my 435 coupe. I did not order the high pressure pump as has been recommended here. The so called regular pressure pump which is what I ordered came with and extra spring. I have read here that the usual extra spring is yellow which should be substituted for the one in the pump. Mine however came with a dark blue spring, almost black. The instructions that came with the pump read as follows: To repair original H/P Corvette oil pumps #3876868 & 3904826 use the enclosed BLUE spring. I have not taken out the spring in the pump yet, but it is a very dark color. Do any of you guys know what I have here? Obviously I do not want to put the wrong spring in and have the oil pressure be to high. Thanks for any help on this.
