We remove the pulsation compensator to replace the fuel rail or the compensator itself
The compensator serves to maintain a constant fuel pressure in the rail when it drops sharply in the fuel line, caused, for example, by a significant increase in fuel consumption during vehicle acceleration
Tools will be required: a wrench for 10 and a tool for disconnecting the fuel line from the fuel rail
The device can be made from a plastic tube of suitable diameter cut along the length
We reduce the pressure in the fuel supply system, as indicated in the article "Checking and reducing the fuel pressure of the 2AZ-FE engine of a Toyota Camry car"
Remove the decorative engine cover
Remove the air filter cover assembly with the air supply sleeve
Remove the plastic safety cover of the fuel line coupling
Insert the tool into the gap between the fuel line coupling and the pipe of the fuel pressure pulsation compensator
After that, disconnect the fuel line from the fuel rail
To disconnect the fuel line, the tool must compress the four spring clips inside the coupling
We unscrew the two bolts of the fuel pressure pulsation compensator
And remove the compensator from the fuel rail
Remove the O-ring from the compensator body.
We replace a heavily compressed, hardened or torn ring
Install the compensator and all parts in reverse order
