Is this the right ink pump?

There are two types of pumps that can be used in the Sp-300 and the one you picture is the old style. There is also a newer style one that only has 1 intake and output see below. Also, be careful with the white tube pumps. Some are not solvent resistant. If the tubes are clear they are solvent resistant for sure.

If your SP300 has the old type installed, you need a conversion kit to mount the new pump. And you need to change a setting of the ink pump motor.
