Make sure your pump mounts have some kind of urethane or rubber bushings =
so there is little to no transmission of vibration though the fender, =
firewall, or whereever you mounted it.  Also check the fuel line and =
make sure its mounted well, that there are not loose brackets, and =
sometimes putting an insulator (rubber strip) between the clamp/hose and =
the chassis helps a lot as well.  Put the fuel line clamps into the line =
spaced out at different intervals, this way the vibration waves will be =
out of sync with each other and not oscillate so much.

If that doesn't help, you need a larger subwoofer, or put on headers.  =
I've found over the years that open headers pretty much drown out all =
the other noises <big smile>.

Cheers,

Fred
