I ran mine near the firewall spot the main fuel to the engine goes. I then ran the line back to the fuel selector and using fitting from Summit racing I tied it all together. The picture of the fittings consists of a AN6 "T", AN6 Female to AN4 Male reducer and an AN6 swivel elbow, this will go to the left tank. The thing then is attached to the left tank part of the fuel selector. I don't know if this is the best solution but his is what I am trying.
