I would caution against using soft solder in this particular application. I had a soft soldered joint at the crankcase end of the oil gauge pipe come adrift during a long fast run in very hot weather in France some years ago resulting in the wife's feet being annointed with very hot engine oil. I re-soft soldered the joint only to have it fail again a couple of years later. Lead alloy solder has a melting point between 166° and 188°C depending on the alloy mix of Tin, Lead, and silver. I concluded that the engine oil temperature was reaching close enough to this point to weaken the joint.
As already suggested I bought all new components from Paul Beck and silver soldered the pipe to fitting joints at both ends of the pipe - never had a problem since in the last seven years.
