Whining sound only when accelerating could be...?

Has anyone foud a fix for this? I think i have this problem whit my 80.

Looks like I posted a few years ago and there wasn't a reply. I had a high-pitch whining sound electrical coming from the middle of the rear middle seats underneath which is where the fuel pump is. I completely replaced all my fuel pump components and the electrical whine for me went away.
