Racetronix listens and delivers… Many customers have noted that there is a wide variation in quality and fitment when it comes to QD fuel adapters. The first problem is that the mating female QD ends are too small to properly fit current-production GM fuel modules. A second problem is that the male QD ends are too short which does not allow for most common release tools to fit between the adapter and the factory female mate. A third problem is that other manufacturers do not offer every combination of QD to ‘AN’ size they may wish to use. Racetronix has addressed all these issues and more with our new quality line of QDA adapters at a price which is sure to make you smile.
