2018 Yaris SE 5MT - T-Sport w/Valvematic! - Toyota Yaris Forums

For reference / interest, this is the setup I used to the clean the injectors. Installed a piece of tygon hose onto the injector at one end, sprayed carb cleaner fluid into the tygon, then put an air attachment on the other end. Secured with hose clamps. It uses the air to pressurize the setup to 10-15 psi; fuel pressure is ~50psi or so, so no issue for injector, but I didn't trust the hose clamps to go too high.. lol

To fire the injectors I had a couple of wires attached to my 12V powersports battery from my ATV for power (not shown). While I held the injector assembly, I had my wife hold the negative on one terminal and rapidly tap the positive on the other terminal. Did this until the injector was clear of fluid. Carb cleaner stinks - do this in a well ventilated area!

Spray patterns looked decent when we were doing it; because of the tip installed on the injector there are two distinct injection sprays - one to each intake port.
