The 040-0430 pump, otherwise known as the "165" pump, is one of the most popular pumps we sell and has been used on Coleman Powermate and Sanborn units for decades (albeit with a couple minor changes throughout the years). This pump is not sold with the Flywheel, but you can use your old Flywheel. It is a single-stage, splash-lubricated, inline twin-cylinder pump with a maximum pressure of 155 PSI. We have the best price on the web for this pump, and replacement parts are also available! The smaller version of this pump is the "130" pump, and is not visually different on first glance, but it has a smaller stroke, with a different crankshaft and connecting rods. The 165 pump is used on 5 HP and higher, whereas the 130 pump is used on units less than 5 HP.
The 165 pump which has been used for the past five years or so has 1/4" FPT & 1/8" FPT outlet ports in head (your old head may be 1/2" and will need an adapter). Part# 68-6-4 is the adapter for old pumps with a 3/8" OD discharge tube; part# 068-0063 is the adapter for old pumps with a 1/2" OD discharge tube.
