I have 2 questions 1st- about a year ago i had a new fuel pump installed. (delco) In the last week i have noticed a sound like a high pitch squeal. I crawled around under the van while it was running. The noise seemed to be coming from the gas tank area. I hope its not the fuel pump going out. It cost $900 dollars to have it replaced. 2nd- i have an occasional popping sound in my right front on accelerations and sometimes when i hit a bump.

First of all $900 for a fuel pump? You got ripped! Sorry ,I just replaced one myself and fuel pump only cost me $214 with life time warenty. if you are the least bit mechanically inclined? Get a piece of plywood about 2ft-x2ft and place on floor jack under gas tank ,siphon as much gas as you can out of gas tank,mark the three lines on the passenger side of the gas tank on top(1,2,3)and dis connect,.jack upplywood to gas tank to hold weight while loosening 2 metal bands(straps) around gas tank, there are 2 bolts on each strap, lower tank to ground and slide off jack,jack up rear of vehicle to slide gas tank from under vehicle, remove the "C" clip to release fuel pump from gas tank. reverse this procedure to reinstall new one. The only problem I had was the new O ring gasket that came with new fuel pump was too stiff not allowing enough clearance to install C clip so I used the old O ring gasket and had no problems. That occasional popping could be a cv axle assuming you have all wheel drive.
