Bart, the AD 81-07-06 Teledyne Continental Motors.; Amendment 39-4071, is simply to check for corrosion and/or sediment in the fuel pump, mainly due to the potential transfer of water from the fuel tanks. The Ad requires annual checking of the fuel pump , and cleaning if necessary / or replacement if damaged. The gaskets on the top holding bolt and the cap are to be replaced to prevent leakage. One of the most important issues is the proper torque of the bolt " 30 +/- 5 inch pounds". Often one doesn't use a torque wrench,a nd tightens the bolt "as needed", leaving the bolt too loose, and the gasket leaks, and often even sucks in air, instead of sucking fuel. Hmmm, bad fuel pimp ? NO, simply serviced poorly. Note the outlet port of the pump REQUIRES a special 45 Deg fitting that has a very small hole (1/16 inch)... This restricts fuel pump from overloading the header tank and the return lines...limiting the output of the pump to about 7 gallons/hr. You must install this fitting into the new pump, or it will cause the header tank to overflow gasoline thur the header tank cap. Fly Safe - Have Fun Harry Francis

I assume the gasket included with the new fuel pump satisfies the requirement for the fuel pump AD. Am I correct or is a special gasket required? Bart
