Pump – GM (86563318)

Factory part number 86563318: a pump supplied by GM. It is catalogued under Motors & Pumps > Pumps.

• 6.0L
• The number stamped on the old part is the only reliable identifier, since two parts can look identical and differ by a millimetre or by rotation direction.
• Fitment lists are a guide rather than a guarantee, because the same model year can carry different parts depending on the production break and the option code.

Genuine parts are made to the drawing the vehicle was built from, so dimensions and materials match the part being removed rather than being close to it.

Match this against the part you are taking off rather than against a photo. If the number is unreadable, send us the VIN and we will confirm it. Ships from our US warehouse in one to two business days, free over $59.
