Add fuel door release?

[co425]

Has anyone added the fuel door release button and actuator to a truck that did not come with it?

I don't know why that the hybrid comes with the remote door but the others do not....

Not yet. I have been researching the relevant cabin switch and the aux switch thread provides info on this. However, I have not yet found information about the fuel door actuator. Maybe someone here has some info?

I thought about it as well but then decided to not do it because in the 30 years I've been driving, I've never had fuel siphoned from any of my vehicles, the labor involved isn't worth my time, and if you mess it up wiring I'm not sure if there's a way to manually open the door without breaking it.

I’m willing to put forth the effort if the harness is pre wired like most everything else. The hope was that it’s pre wired and basically everything else required just bolts in. Minus maybe painting a fuel door.

I too would not mind doing some work just as long as the wiring is already in place. Kind of like the bed scene lights was not that bad.
I'll keep an eye on this thread.

There are some good online parts diagrams posted here:

https://toyotaparts.lakelandtoyota.com/v-2024-toyota-tacoma--trd-off-road--2-4l-l4-gas

This is for a gas TRDOR, but clicking on the page tree at the top takes you up a level and you can select any model Tacoma you desire, making comparisons between gas and hybrid parts relatively easy. Click on “Browse Categories” and then find what you’re looking for. The fuel door etc. is listed under Air & Fuel Delivery then Fuel Storage. I also checked electrical and other areas.

It seems like the fuel door and the fuel filler assembly are the same between gas and hybrid, though different for 5’ and 6’ beds. This is encouraging. The two items that will be required, assuming the harness is already pre-wired in the truck, are the dashboard switch and the fuel door actuator, which have part numbers:

Switch 84841-0A030 $77.22
Lock actuator 77030-AK010 $184.08

This still needs checking with a dealer, and I have not investigated the wiring yet.

Wow. Good info. Thank you.

I’d love to add the fuel door actuator!
hopefully everything is prewired as others have stated. Can’t be that difficult as long as we have all the parts

Did anybody follow through with this? Only reason I want to do it is to prevent the door from popping open in the car wash. Heck, I'd be happy if somebody even offered a stronger spring...

From a design perspective, I would have likened Toyota to use a door without a finger lift, that worked on contact. Press-in and release to unlatch. Press closed to latch. The finger lift detracts from the body lines and looks clunky.

If the desire for a locking door is to mitigate against theft or siphoning, I'm not sure that is an issue?

Times past filler necks were simple, straight pipes. Now, there are flaps, screens and restrictions, to prevent fuel from escaping in the event of a rollover and to control vapors for emissions.

I've watched people attempt to siphon fuel from other late model vehicles; it's difficult, time-consuming and if it does work, it takes forever to remove the fuel (small hoses to combat the restrictions). While the thief won't mind, the Owner/Operator risks damaging any of the filler neck and tank assemblies during the attempt.

My understanding is that the button on the hybrids does more than just opening the fuel door. The hybrid fuel system is pressurized and when you hit the button it depressurizes it then opens the door so there has to be some kind of interface with the ECU.

I'm guessing that the non-hybrids either aren't wired for it or, if they are, it isn't as simple as adding the button and actuator.

Here's a reddit thread about someone with a hybrid where the door refuses to unlock:

Not just that, but with fuel tanks going from metal to plastics, fuel thieves just punch a hole in the tank. Way faster and less-noticeable to passers by.

A quick update. I have bought a few parts in the recent sale, learned a lot about the published parts lists but now have most of what is needed to add an electric locking fuel door. A few more items to clear up, but a full write up coming soon.

So there IS hope for us non locking fuel door meer mortals!
Looking forward to your enlightenment.
