It should be noted that injector nozzles and manifold valves are supplied in two ranges. The nozzles have the size stampled on the hex (i.e. D13B) and replacement parts should be ordered with the same markings as those on the parts being replaced. The manifold valve will either be stamped with an "M" of "P" with the letter size of the nozzle. To order replacement parts for a valve stamped "M" or "P" order with the same markings as those on the part being replaced (i.e. 631427A7M). For those valves stamped with the letter size of the nozzle order the new part in accordance with notes *9 and *10.
