Hi. I have the retrofit pump and I keep having a fuel leak coming from the threads on the pump. I’m using a 1/4 NPT fitting and I’m afraid to over tighten it. At first I didn’t use any thread sealer, but even when I used a sealer it worked for a few minutes, but started leaking again. I’m gonna try again using a gasoline rated Teflon tape when it comes in. Is there anything I’m missing? Also, if there a torque spec I can get for the fitting. Thanks!
