Fuel line connector

If it is a compression type fitting I usually use about a 1/4 turn with a wrench after it's hand tightened. What type connector do you have?

Like Garrett, I just give it a good tight fit.

If you need to put a hard number on it, This should put you in the ball park.

as per the Parts Manual

90 in lbs  s for the banjo bolt

Thank you for reply. I attach a photo of the carburetor. As in the other answers, is tightening torque 90 pounds OK?

Yes, 90 in∙lbs.  Not 90 lbs!

It will not be a lot of torque.  

An Easy, one hand operation.
