I searched the HAMB and other online sources but can't quite find the answer to my problem. The right front connection from the brake line through a thru-frame connector and out to the brakes continues to leak. I'm using 3/16" brake lines. A brake line runs across the front cross member (pic1) to a converter fitting (from female flare to male 1/8" NPT) (see pic2) and then into the thru frame connector (pic3 and pic4). In infow side of the thru-frame connector is 1/8" NPT and the outflow side is AN3. It leaks at both connection on the converter fitting. I cleaned up the NPT threads with a die, and have tried it with and without teflon paste. I've replaced the cross member brake line and flare fitting twice, I'm on the third converter fitting and on the third thru-frame connector (a Speedway product). I've loosened and re-tightended all connections multiple times. I've carefully cleaned the fittings. No improvement. My questions: 1. In plumbing this car, I've never had any issues with AN3 connections. Does anyone know if there is a thru-frame connector for a 1-1/2" deep frame that has AN3 connections on each end rather than just one end? All the ones at Summit, JEGS and Speedway are the same as mine. 2. What am I doing wrong or missing? Any help would be appreciated.
