FRS, BRZ, GT86 and VA WRX Fuel Starvation Fix

For multiple years the FRS/BRZ/GT86 track community has battled fuel starvation with sweeping left-hand turns; typically when running E85 or when boosted (when fuel demands are a bit higher than OE setup) and running less than 7/8 - 3/4 of a tank.  Earlier this year we purchased multiple pieces of this puzzle to tackle this issue.  What we discovered was an easy fix that greatly reduced fuel starvation in left-hand turns.  Below is a short video describing what is happening and why our fix works.

This was designed as an inexpensive fix for the typical track day goer.  While it has been used in some fairly high g-force producing vehicles with great results, even at under 1/4 tank, it was not meant as a replacement for a properly plumbed and operating surge tank!  So if you are competing with the vehicle, we would suggest leaning towards a fully operating surge tank setup to ensure steady fuel delivery.
