If it still leaks you can use ezturn sealant on threads

Matt you mention no sealant regarding the crush fittings. How about thread sealant on the pipe threads going into the tank fitting? Thank you.

I looked thru 43.13, Cam-18 and the A&P handbooks and cannot find a listed torque for a AN775-5D Bolt, you could always use german torque, which is gootentite, ie tight enough not to leak.

Matt, what is the torque on the fitting? It is an aluminum fitting on an aluminum tank. Thanks.

yes, they are crush gaskets and should be replaced, if everything is correct, they will not leak, no sealing compound needed
