Precleaner for engine air intake and methods

A liquid applicator having a collapsible liquid reservoir with an elongated outer chamber wall having a characteristic length, and a liquid delivery piston having a length substantially equal to the characteristic length, wherein the piston is telescopically received in the outer chamber wall, and an elongated intermediate chamber wall having a length substantially equal to the characteristic length and wherein the intermediate chamber wall is telescopically received in the outer chamber wall located circumferentially intermediate the piston and the outer chamber wall, wherein the liquid reservoir and piston may be telescopically expanded to either a fully expanded condition wherein the combined length of the liquid reservoir and piston is about three times the characteristic length or a partially expanded intermediate condition wherein the combined length of the liquid reservoir and piston is substantially less than half the length of the liquid reservoir and piston in the fully expanded condition.
