Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Note: The standard work for the laser mark has been updated.Problem
Illustration 1 g06273667During laser marking on these Reman 3400 HEUI injectors both Prime and Non-Prime injectors were marked with NP. This caused confusion with dealers and customers. The NP is thought to mean "Non-Prime" and the injectors are Prime injector part numbers. The prime injectors marked incorrectly with NP but were built and tested to the correct Prime part number and should be used in fuel systems for prime injectors. Dealers can remove the two letters if they decide the two letters cause too much confusion.Solution
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.

Prime HEUI injector
NP stands for "Non-Prime". Going forward only "Non-Prime" 3400 HEUI injectors will have the NP laser mark.
