i hear my fuel pump constantly running is this normal...and asso when im at a stop sign and i hit the gas it sounds like my leafs or my axle is shifting , also when i make a turn it sounds like it moves side to side

 

its normal to notice the fuel pump noise after you modify certain parts of your rig .... i.e. rhinolining the floorpans ... removing the stupid plastic panels and stuff like that ... its always making that humming noise people just dont really realise it because most pumps are directly on top of the tank and not off to the side like ours ... as for the shifting of the vehicles suspension .... what kind of lift do you have ... do you still have sway bars ? all of this will factor into the "drivability" of the truck ... my buddys F150 is lifted 13.5" with 37.5" tires on it and whenever im in the truck im just waiting for the whole thing to fall apart thats how bad it sounds inside lol but it hasnt happend yet
