'99 Silverado, Drop Tank or Lift Bed

[bigdump]

I did mine at about 65,000 miles. I would definately take the bed off. Took three of us to walk the bed out of the garage, and you can sit on a stool to do the rest of the work. Total time with putting the bed back on was about 1 1/2 hours and a few beers. Avoid laying on your back when you can. Just my .02.

I dropped the tank. I found it easier to remove the drive shaft first, this gives you all kinds of room to manovor your tank around. By the way I have a spare sending unit for a 2001 silverado, the motor is a 6.0

well im replacing my fuel pressure regulator today cuz it wont run at all.i then dismantled the regulator and put it back in.now the truck will run, just really bad, which leads me to believe its only the regulator.unfortunately, i have also had the "guage jump" since i got the truck like so many others.and even tho i replaced my filter, the pump has always whined.advance says a sending unit is $350 so i dont wanna do that.but anyway,to get to the point.im doin this in my driveway pretty much alone, so i never really entertained the thought of pullin the bed.if i gotta do it im droppin the tank.ive taken many out before and its not so bad doin it again.

If the fuel pump runs (as yours obviously does), disconnect the fuel lines and short the f/pump relay to pump the gas out with it - this will make it a snap to drop and reinstall.

If you decide to drop the tank.. keep in mind that gas is 6 lbs/gal... or in my 34 gal tank.. 204 lbs full!

Too bad you don't have more time. Ebay has some GREAT prices on the pumps with sending units.

I've done one or two. Dropping the tank takes about 20 minutes if you're not slacking. I doubt that bed removeal would be anywhere near that fast.

Also, pumps can be had for under $100. A sending unit can be repaired instead of replaced. Usually, it's only the bifurcated wipers that lose tension, and/or the pivot wears and allows some play and poor contact.



Another thing to check closely is the connector in the top of the tank. They frequently fail from overcurrent/heating.



You can get a replacement harness for about twelve bucks.

I know this might not apply, but July 3rd I replaced the fuel pump in my 97. Unbolted the bed, lifted it up and moved it (with the help of several friends) changed the pump, lowered the bed and all was well in about an hour.

Total cost = $106.50 for the new pump
