Well, it's not the fuel pump, I dropped in a new toyota factory fuel pump. Now I have a spare! <img src="/forums/images/graemlins/shiner.gif" alt="" />

I swear it's louder driving home at night than going to work in the day, probably just less traffic noise at night.

I am now fairly certain that I'm coming completely unglued. <img src="/forums/images/graemlins/scared.gif" alt="" />

Anyone want to crawl around on/under my truck to locate the noise? I promise I'll keep the speed down below 50mph....
