900ml i think, how big are the rc4wd cylinder you are using? im sure someone said they are 18mm? As for the tank, use an rc car/heli fuel tank much better capacity

Outside is 19mm but the piston gasket is 16mmID @1.5mm thick so about 17.5mm or so inside bore.. i have to measure it again for exact sizes. The shaft is something odd like 7.6/7/8mm however. Really weird number

for some reason at first i thought they were 14. not sure why
