Re: Fuel Pump Mounting Question

From what I have found out on the subject the fiber washers and spacers are to isolate the fuel pump from any source of heat to help prevent vapor lock. The need in this case for safety wire is due to the fact that the mounting bolts are tightened against a fiber washer without the use of a steel lock washer. The reason safety wire isn't used everywhere is because lock washers are used instead.

Yes, do safety wire the bolts on your fuel pump.
