Hi guys,
I used a Holley blue pump which made a real racket prior to turning the engine over - ignition on and read.
It also was noticeable when I was idling at lights etc.
The engine shop advised me to mount the pump on a plate and then use rubber between the plate and the mount point.
Used lots of rubber washers between washers,bolts, nuts also.
The end result is that it is still noticeable but a lot of the vibration noise is gone. A slight humming is heard during pre start and none whilst idling.
Cheers
Bernie
