Examined Fryer Electric unit, found leak coming from return valve where handle connects. Tightened connections but still leaking. Will order parts and return. 10-11-18 Pulled out the fryer and drained the oil into the sump. Loosened a fitting and noticed a puddle of oil on the floor. Found the oil sump pan with a hole in it. It was cracked. The manager made a phone call and said to go ahead and replace the fitting I had and not to obtain a filter pan (sump). Did as directed and replaced the return valve. Had to manufacture a new pin to replace the cotter pin that fell apart when pulled out of the old valve.
