Fuelpro fuel controller was removed due to a circuit board failure so I just hardwired the primary Walbro 450lph pump. Change all rubber hoses, which will eventually expand and crack, to Flex tech reinforced heater hoses. I had a small leak with the turbo return line that I used 90 degree -10 an fittings, steel braided hose, and the Tigwerks -10AN male to o-ringed fitting into the block so I bought a 45 degree -10AN to barb for the return from a flange fitting with a gasket to the chra and a 90 degree -10AN to barb to the Tigwerks fitting and Flex tech silicone hose with some ss worm gear clamps.

To move the K&N filter away from direct heat soak from the turbo I added a 45 degree elbow and I cut up the stock air intake duct to get air to the filter. Also covered the ic piping with some aluminum 2.5" sleeves. I also had to get a new 4 port boost solenoid due to the original one failing.
I also extended the fuel pressure sensor to keep it away from heat soak and engine vibration.

Still using the Radium catch cans which I have to empty after doing any wot pulls on the freeway onramps. I still don't trust air oil separators. This also keeps my regiment of checking the oil levels frequently.
