Thanks all for reporting back on this. I experienced my first fuel pump failure almost exactly like
@porkandcorn described (304k miles in my 2006 LX) after 4 hours driving in 100degF heat as I waited in line at the ranger station to check the family in to the camp site. After cooling, it started up again and got us the rest of the way and back home after the weekend was over. Some things I learned after completing the complete disassembly and re-assembly three times...(#1 install: replacing the OEM failing part with the Denso #950-0210 while I waited for the OEM 23220-50160 to be shipped to me; #2 install: installing the o-ring that came with the Denso #950-0210 after finding that install #1 wasn't sending fuel; and finally install #3 when the OEM 23220-50160 arrived at the dealership with the clips, filter, and suction gasket replacements.
This video on youtube was EXCELLENT.
although this shows a different style pump assembly than we have on our 2006-2007 trucks
#1 you don't have to remove the 2nd row passenger seat to get to the access port, but it is a little easier.
#2 a bungee cord was easiest for me to hold the carpet up after trying the nifty seatbelt trick shown in the youtube video above
#3 pay attention when
@SuperExciteBike and
@zipdoa BOTH tell you to remember the o-ring.
#4 if you don't follow the suggestion to relieve/empty the fuel line back pressure, be ready with a towel or shop vac to suck up the gas when you disconnect the fuel lines
Tools needed in the order used:
- small flathead or pick to remove the plastic covers on the plastic step platforms that we step on when admiring the roof,
- 10mm socket (and backup 10mm) to remove said platforms
- 14mm socket for the seats,
- T20 Torx for the plastic trim pieces that hold the carpet down around the seat anchors
- flathead screwdriver to back out the plastic clips
- vacuum to receive the fuel that is spraying out of the fuel supply line because you didn't listen to @SuperExciteBike
- 8mm socket to remove the screws holding the pump assembly to the tank
- bucket to put the pump assembly in to transfer out of vehicle and not spill fuel everywhere
- bent needle nose pliers to remove the fuel line hose clips (of course other styles will work, but these are easiest for me)
- For OEM 23220-50160, just install the replacement and reverse the steps (O-ring is already installed and ready to go)
- for Denso #950-0210 you'll need a small flat blade to remove the white plastic retention cage from the black plastic cage so you can slide out the old pump
- Note for Denso: Please...please....seriously...make sure you instal the o-ring that came in the plastic bag. It goes in the TOP orifice/exit of the pump before you push the pump back into the black cage and reattach the white plastic retention cage that the filter bag is attached to.
Because I'm curious, I took apart my failing OEM fuel pump to learn how it works. Did you guys know that the fuel is drawn up and THROUGH the motor?? The fuel is drawn up through the stator windings, magnets, and commutator brushes to cool it as it flows past and out the top. So the entire internals of this pump are constantly submerged in gasoline! Maybe you all already knew that but I didn't and thought that was fascinating. Also, what looks like a potential mold/casting flaw in the fuel pump pick up port, is actually an internal nozzle to support fuel suction. I panicked a bit when I first opened the denso and thought I got a dud.
