Looking to buy Fuel Drain Kit so I can drain the fuel from my tank at the fuel rail. I am aware that the newer (2018 and up) fuel rails have a schrader valve that makes this so much easier. However I am a 2016 and not looking to replace the rails.

OST Dyno has this on their website, but not a way to purchase (I’ve called them and emailed):

Hellcat Fuel Tank Drain Kit - $35
This kit allows you to seamlessly tap into the factory Hellcat fuel line at the fuel rails. Jumping the fuel pump relay in the trunk with the supplied jumper will allow you to drain the tank for race fuel tuning or track days. Instructions are included to eliminate any guesswork.

Anyone know parts/part numbers so I could build one myself or where I can get one?
