Hi Svein,
For any threaded fuel joints I recommend that you use Hylomar sealant
which is a non-hardening product developed by Rolls Royce many years
ago. It is used widely in many high performance applications. You can
find information and suppliers with a Google search for "Hylomar" or
"Permatex Hylomar". You need the 'Universal Blue' product. For clean up,
you can use methylene chloride.
I do not recommend that you use Teflon tape. This product is forbidden
in the petro-chemical industry after catastrophic plant failures have
been traced back to small pieces of tape which have blocked critical
control instrumentation orifices.
Cheers, John

Subject: Europa-List: NPT threads
Should I use any kind of sealing on NPT threads in the fuel system
(e.g.Locktite)
or do these threads seal just by using the recommended torque? Regards, Svein
