The mounting holes in the pump are much larger than the bolts that go through them. This space was taken up by little insulator bushings to cut down heat transfer. In additiion, there were insulating washers under the washers on the bolts. Often, all of this stuff is missing.

When the bushings are missing, I cut a strip of thin gasket paper and roll it around a bolt to make a tube and then stick it in the fuel pump flange. I make the insulating washers from a couple of disks of gasket paper cut with a punch.

Without the bushings it is possible to put the pump on either crooked or too high or low.
