•Make sure that the fuel line is secured away from the turbine housing when the
turbo is installed. Some bending of the lines is necessary to achieve good
clearance.
•Make sure the lines are properly wrapped twice.
•Make sure to use safety wire to wrap the thermo cloth. Zip ties will melt from the
heat and eventually will come off.
