Hello,i just signed up yesterday. In the past i have found some good,information at this site,so i decided to join in. I have owned a 75 280Z, for 31 years original owner. I try to do most all maintence and service myself now.In the past i paid a mechanic to do all service,restoration etc. If anyone has any ideas of why a newly replaced,(rebuilt) fuel pump is squalling like a banshee.The sound inside is unbearable! Let me know your ideas. People at Courtsey Nissan,TX. said check (Dampner) Guess what its NOT there, I have no dampner! Anyway any thoughts or *fixes* will be appreciated.
