Toyota Genuine Parts - Cap Assy, Fuel Tank (77300-06040)

2009 Tacoma.

There’s no replacement for these OeM gas caps. This one is legit. The cheap ones throw codes.

Perfect replacement

Application: 2010 Toyota Tacoma TRD Sport DCSB I want to first point out that while this is an OEM product and arrived in a legitimate Toyota parts packaging, there are some subtle differences to the text on the cap. I’ve included some pictures (old OE cap on right and new on left) so you can see the texts differences. No big deal - doesn’t impact functionality but I’m a stickler for details so it is worthy of pointing out. As for my problem: I noticed about a year ago that my gas cap was not always giving me the “1-click” when I finished at the pump. I’d have to try several times before I felt like the cap was on correctly. A quick search on a Tacoma forum indicated that this is a common problem for owners. As time went on, I would get sporadic check engine lights. The codes were not always consistent with an EVAP leak or something that would point to the gas cap but resetting the ECU (disconnecting the battery to clear codes) and tightening the gas cap would keep the check engine light at bay for a few more weeks. Eventually, I decided to look up the OE gas cap part which brought me here and when I saw how cheap it was, decided to purchase. There are several off brand alternatives here on Amazon when you search the part number. They are cheaper but OE quality is worth an extra $3-4 dollars in my opinion. Install is a breeze. Grab some pliers if your old cap still has the tether in tact and yank it off the fuel door. Press fit the new tether in place and you’re ready to go. I’ve been check engine light free for several weeks now. The “1-click” is back and the difference was noticeable right away. Even comparing the old cap to the new one, it was easy to see how ineffective the rubber gasket had become. TLDR: Quality product that serves a basic function but could also save you a ton of hassle if you’re not mechanically inclined and your Toyota is throwing a check engine light pointing to a leaky gas cap.

I was receiving error codes on my 2010 Toyota Tundra. I purchased one of the generic gas caps off Amazon which didnt resolve the issue, nor did the replacement. I purchased this OEM gas cap and my CEL went away. Highly recommend this product, stay away from the non-OEM gas caps.

I don't think this is a geniuine Toyota part. The cap doesn't click when tightened and the text on the cap is different. The photo shows a gas cap from the Toyota dealership on the right. Notice the lettering is different. The real Toyota cap uses an upper case U in the word Up and a period at the end of the sentence. Not and OEM part. Cap doesn't seal and check engine light is on. Not compatible with my Toyota Tundra.

seems like quality and it fits

Good!! It was a perfect fit for a 2011 Toyota Venza.

Le bouchon est vraiment bien fait et il fonctionne comme il faut.

So happy to find a replacement for my lost gas cap on Amazon. The gas cap came quickly and fit perfectly!

It's a genuine gas cap, what else is there to say?!

Perfect fit—installed with zero issues. Even at -27°C here in Canada, the rubber stayed impressively soft and flexible, which says a lot about the material quality. Clearly a genuine OEM part. Highly recommended.

Fast delivery and the same as the picture.
