Description of Change: The alternate pressure gauge is filled with silicon to dampen the vibration of the needle inside the pressure gauge.Since the alternate 190-6637 Pressure Gauge has a 1/4 inch thread size and the previous gauge has a 1/8 inch thread size, the mating fitting will also require change as shown in the Table 1.An alternate course of action is to replace the gauge and fittings with a 5M-6214 Pipe Plug (9/16 inch thread) or a 9S-4182 O-Ring Plug (7/16 inch thread).Adaptable To: The alternate 190-6637 Pressure Gauge is adaptable to the above engines back to first production.The alternate 190-6637 Pressure Gauge replaces the former 266-0889 Pressure Gauge and the 295-0758 Pressure Gauge.
