I have a hand pump that fits the Mobil175w90 bottle but it is too small of a diameter cap to screw onto the WS ATF bottle that has a wider mouth. Anybody know where I can get a pump to fit the Toyota WS bottles???
I had the same issue and just transferred it into a standard size bottle. There maybe one out there that will fit those bottles but just transferring it to a regular bottle while being slightly annoying is an easy way to get the project going.
