A tank for a dry sump lubrication system for an internal combustion engine, the tank comprising:
- a body having a first portion, a second portion separable from the first portion, and defining an inner chamber;
- and
- a filter housing formed in one piece with the first portion and disposed partially inside the inner chamber and partially outside the inner chamber, the filter housing is configured to receive a filter,
- wherein the body and the filter housing are formed by a blow molding process,
- wherein the filter housing defines a first wall that extends into the inner chamber and a second wall that extends outside of the inner chamber, the first wall extending inside the inner chamber more than the second wall extends outside of the inner chamber,
- wherein the first and second walls define a cavity to house the filter, and
- wherein the first wall defines a bypass conduit that fluidly directly couples the cavity to the inner chamber.
