Having not done it before I would prefer to not have all of that the extra weight in the tank. A half a tank is nearly 55 lbs.
fair enough.. Ive had pretty good luck with cheepo syphon pumps. you can get them at walmart or menards, may take a couple min but its really not bad
since its your first time....
The tank has 7 bolts holding it up, there are two creases along the bumper side with bolts inside them. the bolts inside those divots are to the gas tank straps and you do not need to loosen or remove them to drop the tank. the tank is strapped to the skid plate and the skid plate mounted to the jeep.
The easiest approach is...
1) remove the filler neck plate from the side of your jeep. should be 8 philips head screws 4 to the actual filler neck and 4 to the rear quarter panel.
2) push the filler neck directly back so that when the tank comes down it wont snag on the inside of that fender wall.
3) use a 2x4 or other plank of wood to distribute the weight of the skid plate evenly and jack to the center of the board under the center of the skid plate.
dont be afraid to put a little pressure on it to keep the tank in place when the bolts start coming loose.
4) remove the 4 outer nuts first, avoiding the two for the tank straps (you'll want the inner bolts in for step
** note: the 7 bolts holding the skid plate up are carriage bolts drop fed from above so be sure not to push up on them too hard or you knock them loose and have a whole lot of fun on your hands
5) let the tank down a few inches, just enough to get to the fuel line coming off the top of the pump assembly, its a pretty tight fit so you don't want the tank to fall too much and damage the clips connecting that to the fuel pressure regulator.
6) jack the tank back up to snug and remove the rear 3 nuts and your ready to slide the tank out. There are two other vent lines that just slide over some plastic fittings one on each side of the tank, pull them off before dropping as well.
** note: pull the tank towards the bumper as you let it down the back of the skid can get hung up on the rear axle and other things.
getting it back in is pretty simple, line up the inner side first jack it back into place.
depending on how old your fuel assembly and tank are. You may want to pull it off and do some simple preventative maintenance replace the bottom screen and check the tank for sediment. all that fun stuff. If you have the tank off already you minaswell
know that if the tank straps or skid plate look bad enough to replace its not likely you'll find anything local so order what you might need before you start the job.
