When converting over to the use of AN fittings and adapters, such as Aeroquip or Earls, how tight should one tighten the -6 x M12 Weber adapters to the lift pump for example. Stock ft-lbs torque or less? I notice they sell the AN wrenches so I figured "hand" tight was sufficient if using these wrenchs. I dont need a broken off adapter in the VP44 port. I've never really worked with such small aluminum threads. Dont wanna strip nothing. And do you use the sealing washer on the adapters? Thanks.
