Re: AC/Blackstone Fuel Pumps

On the subject of fuel pumps, my Series 23 pump has the mounting bolts lock wired to keep them from falling out. Is that a standard Packard way of doing it? The installation of the lock wire is a (bad word). I can understand the need for lock wire if the torque on the bolts has to be reduced to protect plastic insulating washers.

Maybe a better way of doing it would be to install studs in the block and secure them with Loctite. Then self locking nuts could be used and torque reduced to protect the plastic washers.

Does anyone know the thickness of the insulating washers and gasket? I would like to use the original design for thermal insulation. I am also installing a heat shield per original.
