Hi Folks,
Just wanted to share some notes on my recent fuel injector rebuild. This all started out as a starter replacement and somehow spiraled into a full refresh of the top end of the motor. If you need to do this, I would recommend buying the rebuild kits available online for the filter and upper seals, but try to use the Toyota parts where you can. All of the injector end-caps were still good on the originals after 260K, the lower seals were trashed. You could probably get by with only replacing the lower seals if you wanted to do this on a budget. I also found all 8 injectors were completely clean so the time/effort spent cobbling together an injector cleaner probably wasn't worth it, but it does offer peace of mind.
NOTE: I had one injector leak due to a pinched an O-ring after I put everything back together. Luckily it was an easy fix, but you take extra care inserting the injector back into the fuel rail.
Here's the before and after:
