The 040-0429 pump, otherwise known as the "130" 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 (or purchase the 040-0425RP pump which does include the Flywheel). It is a single-stage, splash-lubricated, inline twin-cylinder pump with a maximum pressure of 125 PSI. We have the best price on the web for this pump, and replacement parts are also available! The larger version of this pump is the "165" pump, and is not visually different on first glance, but it has a larger stroke, with a different crankshaft and connecting rods. The 130 pump is used on units less than 5 HP, whereas the 165 pump is used on units rated for 5 HP and higher.
When ordering this newer-style 130 Pump, you can use the Head from your original pump, as it will retro-fit onto the new Pump. This is necessary for older pumps that have two outlets in the head; the new pump Head only has one outlet in the head (for your main discharge tube).
