I got the flex fuel sensor, but of course I got the wrong one to work with the Motion Raceworks holder...



I was missing one last fitting to complete the intercooler hoses. The inlet to the intercooler needs a 45 degree fitting in order to clear the fuel rail that is below it. I used the fabric heat shrink on top of the Earl's Super Stock hose and it looks remarkably similar to the Earl's Ultra Pro hose.



This hose makes a gentle sweep down and towards the center of the fan shroud...



Where it connects to the water pump. You can see the pump mounted to the fan shroud.



Vic took a couple of fittings and welded them together to make an adapter.



The adapter is used to mount the pressure relief valve.



Carl from VaporWorx told me this was necessary to keep the system from getting vapor locked. He told me to purchase a small Radium Engineering fuel pressure regulator and send me a special 80psi diaphragm for it.

When the car has been running for a while, then it is turned off, pressure in the feed line can build up and lock up the injectors from firing. This valve will burn the feed line once the pressure exceeds 80psi.

I also got a modern Helical exhaust valve that uses a Küster 3 pin motor. This will be controlled by the Holley Dominator ECU. Not sure why the video doesn't show...Just click the link...
