    Saving a Santorin Avant

    Fuel system pretty much complete.

    Running Fragola 6000 series ptfe lines, -8 feed up to the rails in parallel, back to an aeromotive a1000 regulator. Mounted a GM flex fuel sensor directly to the return side of the regulator to read ethanol content and fuel temp, and a -6 return line from the sensor back to the tank. Will also have a sensor on the regulator to log fuel pressure. Mounted a Radium 6 micron micro glass fuel filter to the underbody behind the rocker panel. Just need to finish pressure testing my lines and tighten everything back down.



    Will be 3D printing a new access panel cover that is bumped out a bit to clear the lines.







    Cramming ptfe lines under the manifold was an exercise for sure. I’m not a fan of deleting shit without a good reason so I have the n80, n249, and a tfsi n75 all hidden under the manifold as well. Looks nice and clean from the top (or will once I finish cleaning up all that wiring) but space is super tight underneath.


    Twin 450’s are all wired up as well. Wiring runs under the rear seat as it does in the factory setup, but don’t have room for my fused dual relay holder under the seat and I refuse to mount it in the spare tire well. Ran wiring up the drivers side bolster and mounted everything where the CD changer sits. 4 gauge wire from the battery runs to a sealed bus bar then to the relay holder. Grounded everything to the chassis using the mounting bolt for the seat belt. Second pump is triggered off a 15psi Hobbs switch.
