Jersey Modeler has some really nice pump set ups for gas,nitro,kerosene and smoke for the airplane guys...but I and several other guys I race with use them for our boats. I have 2 seasons on mine 3s lipo electric pump version.(manual hand pump also available). Unit is also replaceable (electric motor, filters ect...) and or can be fitted with a manual pump. I race with some guys that have years on their set ups for nitro and gas.
