I have a couple of new hosetails that I need to seal into the top of my diesel tank and was about to buy some fancy thread sealant when I came across a thread on here that recommended using CT1 to seal pipe threads. The CT1 website says it's recommended for diesel. My question is, I have a tube of OB1 and was wondering if that will work for diesel pipe fittings as well. Anybody used it?
