On my 96 4.0 I found it easier to get to the filler tank hoses/clamps off if you remove the driver's side rear plastic wheel well flap which is only held on my 3-4 screws. And spray the filler tube with some PB too and will make the hoses easier to remove.
Couldn't get to the rusted clamps on the hoses on the tank itself so I just pulled the hoses through the frame with rags stuck in the hose ends. Made it easier to remove the metal exhaust shield on passenger side which is held on by three 10mm headed bolts.
Washed my tank out with soap/water but one problem is that it's a bear to get it all out since there's a baffle in front of the hoses inside the tank so it won't just pour out. Also the tank hole is recessed. Finally mopped the rinse water out with a rag and let it dry in the sun before installing.
As others have said it's best to use a floor jack with piece of plywood which fits between the tank straps. My strap bolts were rusted so bad had to use a lot of PB/wire brush and kept going forward/backward so rust wasn't building up on the nut threads. Also hold these bolts at the top with vise grips so you don't twist them out of the body. Only have to loosen them about half way and then lift the curved part of the bolt out of the slot in the body at the top.
Don't believe you're going to find any better price on a new pump assembly than this new Bosch 67649 for $120 with free shipping. The fuel regulator and check valve are built into the assembly while it comes with a new filter on the top. Bosch is the OE replacement on fuel pumps and mine runs real quiet. The vendor (e-herko) is reliable and others here have had real good luck using them. Good luck!
