Lynn,
In "A "are you saying a silicone hose with s spring insert or is it just a hose piece joining two metal tubes together. What I'm concerned about is degradation from heat and oil as well as hose collapse.
George (down under)
In the picture, "A" is two  views of the engine end of the new oil pick up. This allows for a hose to be slipped over the tube and clamped in place.
 
Item "B" Is both a front and rear view of the offset pan construction.
 
Item "C" is both a left and right side view of the offset pan.
 
Item "D" is one view of a close fit pick up. Where a tube is laid onto a pickup flange in line with the mounting holes. One mounting hole is still exposed, but the other is covered by the tube. The tube is plugged with a disc of the same material. The covered hole is drilled out so as to puncture the tube in two places. The holes are deburred. A small tube is installed between the holes to prevent the tube collapse when the longer bolt is tightened. A washer is added to the top of the tube to provide a seat for the bolt head.
 
All radius filled with braze and smoothed. The flange is radiused inside the tube.
 
Sorry about the pictures. All I have is MS Paint.
