Holley eletric pump sometimes louder!! Like bad loud??

The other thing i forgot to mention, is i am not sure that the holley elec pump is designed for "continuous" use. I know the Aeromotive pumps had a 400 hr life span to them, that was years ago, i am sure that has been addressed. Barry grant pumps had all sorts of issues as well.

When i had my camaro, i had an SX pump on it, was designed for 1000 hp and continuous use. It took a #10 feed and an #8 return line, that hurt the pocket book. But that pump is still on the car after 10 years no issues at all.
