Anyone know if there is a service port easily accessible on the fuel rail or nearby? Schrader valve?

PIFFF! Service Port!? What the hell do you need one of those for!
Joking aside, Toyota doesn't seem to put service ports on our fuel rails usually; I have no real clue why... BUT, if you need to hook a gauge inline, test fuel pressure, and/or run some injector cleaner through the vehicle the feed and return lines are quick disconnects located near the brake master cylinder, just remember to pull the fuel pump fuse when you have them disconnected and to block off the return if you're trying to run injector cleaner through the vehicle.

Hahaha! Honestly out of pure random curiosity! I have a pretty cool injector cleaning setup I was thinking about trying out but I'm not sure it would even be worth fooling with. What are your thoughts on that service on our toyotas? These things run so damn clean I would be surprised if it would need it but I don't know!?

We do injector cleaning at the dealership, so it shouldn't be an issue.
