Narrative:

After a local training flight and a series of touch-and-goes, engine failed upwind of runway 4 at fpr. After executing 180 degree turn and checklist, engine was restarted on short final to runway 27. Engine windmilled at all times. Student preflted aircraft, told me 1/2 tanks of 72 gallon capacity. I visually confirmed this, both gauges also read 1/2. Never trust gauges, lesson #1. After landing and shutdown, only 2 gallons in each tank. Lesson #2, never eyeball fuel. According to maintenance, vapor entered lines due to low fuel and caused the engine to quit. As it was windmilling, when the residual fuel entered line, power was restored on short final. Had it not been for the perfect conditions allowing a 180 degree turn back, the outcome may have been disastrous (after engine failure).

Title: A PA28-201 INSTRUCTOR PLT PERFORMS A 180 DEG TURN FROM UPWIND LEG AND AN EMER LNDG AFTER AN INFLT ENG FAILURE DUE TO FUEL STARVATION ON A TRAINING FLT NE OF FPR, FL.

Narrative: AFTER A LCL TRAINING FLT AND A SERIES OF TOUCH-AND-GOES, ENG FAILED UPWIND OF RWY 4 AT FPR. AFTER EXECUTING 180 DEG TURN AND CHKLIST, ENG WAS RESTARTED ON SHORT FINAL TO RWY 27. ENG WINDMILLED AT ALL TIMES. STUDENT PREFLTED ACFT, TOLD ME 1/2 TANKS OF 72 GALLON CAPACITY. I VISUALLY CONFIRMED THIS, BOTH GAUGES ALSO READ 1/2. NEVER TRUST GAUGES, LESSON #1. AFTER LNDG AND SHUTDOWN, ONLY 2 GALLONS IN EACH TANK. LESSON #2, NEVER EYEBALL FUEL. ACCORDING TO MAINT, VAPOR ENTERED LINES DUE TO LOW FUEL AND CAUSED THE ENG TO QUIT. AS IT WAS WINDMILLING, WHEN THE RESIDUAL FUEL ENTERED LINE, PWR WAS RESTORED ON SHORT FINAL. HAD IT NOT BEEN FOR THE PERFECT CONDITIONS ALLOWING A 180 DEG TURN BACK, THE OUTCOME MAY HAVE BEEN DISASTROUS (AFTER ENG FAILURE).
