Ok so I have had a big gas leak in my RX for some time now. It is not the PD and I cannot seem to find the problem. I took off the TB and still cannot see the leak. It leaks from the back of the motor, maybe from the line that goes to the fuel rail. I am not sure. Does anyone have any suggestions??? Thanks a lot.

 

did you check the lines going to the fuel filter and coming out of the fuel filter?
