Fuel system thread sealant

Hello

I am replacing my Yamaha fuel flow transducer.

What sealant is recommended for the threads where the nipple threads into the sender unit.

I'm not going to used teflon tape.

Use the teflon pipe sealant, paste type.

I use gel seal or Loctite 518 as well, depends on whats handy.
