Its a pretty simple system(but costly)... really all
you have is 3 major parts.... pan(really any pan can
work), the holding tank(this is where the oil is held,
and the biggie... the pump... they have different number
of stages... when they talk stages they are saying
how many suction sections AND the pump section...
mine is a 4 stage pump... 3 suction sections and 1
pump section... you will also need a breather/puke
tank for it(some holding tanks have it mounted on them.
Ok so far we have talked about the major parts...
now you need a drive system for the pump,,,, and ALL
of the lines and fittings... a complete system will
run ABOUT $3000 depending on the pump... lines and
fittings can get crazy pricey
