I've used the bosch and the airtex and both are quiet. Almost silent with the car off (and pump running). Can't hear when car is running. Are you using the stock rubber isolators and the rest of the stock mounting? The rubber sometimes gets rotten, so people ditch the rubber and use zipties or something else to hold the pump. If you use all the stock mounting and the rubber is in good shape, it should be quiet.
Another thing to look at is the pumps will become loud if you have some restriction in the lines or pickup tube. A friend I was helping had an SE that would idle great, but would die if you tried to drive it. Sounded like a fuel issue, so he replaced the pump and filter..problem still there. The pump was louder than it should have been also. Fuel pressure at idle was fine, but if you tried to drive (even a couple feet), pressure would drop to like 10-15 psi and the car would die. We did a fuel volume test and it was wayyy low. Found that the pickup and return tubes in the tank were totally clogged up. Cleaned the tank, cleaned the tubes, and all is good now. :) You may have a partial clog somewhere in your system.
