This is such a simple question it's almost embarrassing to ask... Anyone know what size cap wrench fits on the 90915-30002 filters for the 1HD and 1KZ engines? I've had two instances now where the filter was so tight it could not be removed by hand. On my 1KZ engine, the filter can't be accessed easily except from the top, so only a cap wrench style will work to get a good grip on the filter. It's definitely 15 flutes... I thought it was a 100mm x 15, but that's too big. The next size down I can find is a 93mm or a 90mm, both of which seem like they might be too small since the 100 mm was close. Since I didn't have the right sized cap wrench, I debated just punching a screw driver through the side to remove the filter, but instead opted for the safer route of removing the fuel filter to get more space and it still just barely worked. I want to get the correct sized cap wrench instead in case it happens again.
