Abstract
An oil pick-up tube for carrying oil from an oil reservoir to an oil pump, comprises an oil pick-up end disposed in the oil reservoir, a pump end disposed in the oil pump, and a transporting tube portion to deliver oil from the oil pick-up end to the pump end. The pump end includes an insert cylinder having outer diameter D and an oil outlet, an outer diameter d tube portion, and a flared portion tapering from the insert cylinder to the outer diameter d tube portion. The pick-up tube further comprises an o-ring seal disposed about the outer diameter d tube portion, wherein the diameter D of the insert cylinder is greater than the diameter d of the outer diameter d tube portion for keeping the o-ring seal about the tube prior to assembly with the oil pump.
