    The fuel line on my 2004 is spitting out fuel right above the gas tank. Looks like corrosion from what little I can see. Since it looks like I'm dropping the fuel tank I was just wondering if I should go ahead and replace other things while it's down. Things such as fuel pump, strainer, other lines, etc. I've never done this before, so I'm kind of guessing here. Any tips would be well appreciated. I'm looking over in youtube land for videos as well.

    Thanks in advance!

    Mileage? Over 200k, I’d be inclined to replace the fuel pump assembly myself (provided it isn’t on back order).

    If you do replace, don't buy parts store brand. The number of people who've had parts store fuel pumps die within the first year (and even DOA and/or first month) on this forum is too damn high.

    Buy Denso brand, look up part# at www.densoautoparts.com

    Or buy the fuel pump assembly (so you get a new sender, new pump, and everything else) from Toyota Parts system online.

    Do not order on scAmazon or fleaBay, risk of counterfeit parts is far too high.

    If you're in the rust belt, you may want to consider replacing the straps. Dorman makes a replacement tank also.

    @Jack McCarthy Yeah, it's at 315K now - that's what I was thinking.

    315k, I'd replace the entire assembly with OEM. Truck should be good for another 300k miles. I realize it's a chunk to spend, but ... you should literally never need to do it again. But it appears you can't buy the entire fuel pump assembly with pump installed for your year. Strange.
    I'd at least replace the sender (83320-34050) and the pump (23221-07010), the screen (23217-0F010) and screen clip (23219-03010), the pump pickup hose (23233-02010) and two clamps (2 x 90467-13054), and lastly the fuel pump gasket that seals the assembly to the tank (77169-04010)

    The fuel tank supply lines appear to be the main supply line (77209-0C030) and the return line (77207-0C030), I assume both are quick disconnect, which may require a disconnect tool.

    1 minute of copy/pasting, no prob. Verify part numbers before order. Those two lines show as being on top of the tank so they may be stubbies, if they're full-length (from tank to engine bay) shipping may be exorbitant.

    Drain the fuel tank completely before you try to drop it! https://www.tundras.com/threads/tacoed-tundra-project.130491/page-5#post-3346692

    The tank holds 26.4 gallons. 1/4 tank would be about 6.6 gallons. Multiply that by 6 pounds and it's only about 40 pounds. That isn't heavy whatsoever, but it will sure get awkward fast when it starts to slosh when you're trying to balance it with one hand...while you're on your back. It would be much more manageable with only 2~3 gallons in it, but it will still be totally doable with 6 gallons. Just be prepared for the sloshing and it won't be too bad.

    Got it down. Seems that what I thought was corrosion was actually a critter taking a bite out of things. It took care of my evap canister hose as well. Sheesh.

    Yup, that's classic, and the point is brought up in the Megathread. Rodents love nesting on top of the tank, and chewing up lines.

    I believe one of those lines is discontinued. But if you need help hunting other part numbers (for EVAP) LMK.
