Good news ! My 45 minute pump change turned into a 6 hour ordeal. I changed out the Holly Blue twice, each time trying to deaden the noise ( even trying a brand new pump ). Then installed a Carter 4600. New bracket, new plumbing, and no noise when engine is running !

I now have 3 used Holly Blues if anyone is interested in backups. 1 is shot, and the other 2 work fine. Just a little noisy, which is partly due to their bracket set up.
