My take on the oiling system crossover tube for the small block

prochargedmopar said

Just got my new 18650 pickup tube and was surprised to see it only has a 3/8" npt fitting on the inlet.
I re-read this post and now see that you modified yours for the 1/2" fitting and it does not come that way.
I will do the same after drilling out the pump.

You have to cut off about 2 inches of the tube in order to remove all of the screw in insert.
I used a black iron 1/2 inch npt pipe nipple from HomeDepot.
I inserted the tube into the pipe nipple then took a center punch and flaired the end of the tube inside the outside tube for a tighter fit before welding it together.
