Way better than flex fuel kits. Made my own flex fuel kit for under 250 total for a 2019 bmw 330i and works perfect

Cheaper than buying a whole flex fuel kit and worked perfectly with my KPro V4 to add flex fuel capability to my K24 swapped EG

Used for a E85 conversion on my 2010 Camaro, has been holding up so far and worked well on the dyno, great for aftermarket use or OEM
