hi guys ,re blocked au 4L fuel pressure regulator , my falcon au ute was burning 1 litre of fuel every 4.4kms so when i had removed the FPR from the rail i blew 100psi into the fuel filter pipe connection that connects to the fuel rail and cleared out a lot of black rusty sooty material ,then blew back into the FPR body and cleared the return fuel tank line, after fitting a new fuel filter and a new FPR valve to the rail body i am getting 10-12kms per litre. saves taking of fuel rail etc and can be fixed in an hour.
