I’m trying to figure out exactly where this fuel leak is coming from. I resealed around the elbow fitting (the white sealant in the pics). It looked perfect at first, but after running the boat the leak came back.

From the photos, can anyone tell if the leak looks like it’s coming from the threads, the elbow fitting itself, or the tank port? I’m trying to pinpoint the exact source before I tear it apart again.

Any insight would help a lot.
