ive got a rumbling in the back end of my car...it only happens when i first start up .....it dosent happen very much and when it does happen it lasts for only maybe 5-8 sec. Usually happens when its hot...but sometimes when its cold.

....my first thought was the fuel pump...but dont those make a high pitched sound when they are going out.

My PGT does this too sometimes and it is in the gas tank. I think either the pump is cavitating or the fuel coming back from the return line has vapor bubbles in it, causing a muffled gurgling sound.

Mine's done it for some time and I stopped worrying about it a while back :D
