As the car heats up there is a noise in the rear of the vehicle that gets louder the longer I drive it. I think it's the fuel pump...it sounds electronic. Does it sound like a fuel pump problem or do you have any other ideas? Thanks

If it was pump, then pull over, if noise is still there, then pump is possibility, if not then a rear suspension component.

To be sure, check fuel pressure with mechanical gauge.
