Message: [QUOTE="TARM, post: 75726, member: 578"] The fuel fittings are NPT and should need no sealant. Sealant on fuel fittings is a dangerous gamble IMHO. Any gets into the fuel its going directly to your injectors from that point. Pre last filter is a different story or the fittings exiting the heads woudl be less of a risk as well. Now if you or someone else over cranked the fitting as you know that opens them up to the point you need to use tape or tap them out to a larger size and change the fitting. Obviously you can not allow a fuel leak to happen so you need to choose. [/QUOTE]
