Fuel leak I can not solve

Hi,
My name is Will and I'm new to the forum. I have a 94 w/ the 3.0 and it has a bad fuel leak. I have replaced the injectors with all new o-rings and seals. New o-rings in the injector cups. The fuel leak continues. Here's the funny part, the leak only happens when the truck is running. The fuel pours off the back of the engine on the passenger side. It started slowly and has progressively gotten worse. I stopped driving the truck and am at a loss as to where this leak can be coming from. Any help is greatly appreciated.
Peace

 

The only way you are going to find it is to either trace the fuel or and use a strong flashlight and inspection mirror. Good luck.

 

Look at the fuel pulsation damper, it screws into the back of the right side fuel rail. You can see it with a flashlight and mirror. Search the Google and there are pictures and videos of the damper.

 

I agree with above post I don't have the 3.slow. I have the slower 22RE but it also has a fuel pulsation damper and it grew a leak. Get OEM.

 

The problem was the fuel pressure pulsation regulator. The diaphragm had split and was the source of the leak. The truck runs great with the new 4-hole injectors and the check engine light is gone after replacing the bi-metal valve and finding a vaccine line on the back of the power steering pump unplugged. A shout-out to Greg and Tyler at Toyota West in Columbus Ohio for helping assure we ordered the correct parts. It's so nice to have my truck back.
