Engine Mechanical problem
2001 GMC Yukon V8 Two Wheel Drive Automatic 132000 miles
----------------------------------------------------------------
MY FUEL PUMP WENT OUT AGAIN......
FOUND ANOTHER ONE OUT OF A 4WD 2000 YUKON
WILL IT WORK FOR MY 2WD 2001 YUKON?

Depends on the engine. You could call the dealer or autoparts store and check part numbers for both years, if the same then you are OK, if not then don't take a chance.
You would need to know what engine the 2000 had in it.

evrything is the same xcept one of the plugs that goes into the fuel pump itself, it was a simple rewire and evrything works...... even used old tank... it was worth the try since i found the pump for 25 bucks.... saved almost $400.00!!!!!! thanks
