Svein,  

   

You have to use a Teflon sealing.  

Normally for instrumentation (industry) we are using Teflon tape, but there is also a Teflon sealing fluid (pasta) on the market.  

Maybe that this is better for “tank” connectors to avoid getting parts of the Teflon tape into the fuel system  

   

Best Regards,

 Betreff: 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

Hi Svein,



Never use teflon tape in the Fuel system.

The reason is that tape shreds and those shreds can get into the

fuel stream and clog your carb, especially if the particular fitting

is downstream from filters.



Use instead PTFE Pipe compound as suggested. it is a paste

available at places like Home Depot or plumbing shops.



Good Luck,



Ira
