I installed the lower tube into the hole in the windage tray, so that the kink in the tube is between the block and the windage tray. Is this correct? In this position, the lower tube is about half-way into the hole in the block, leaving half of the hole for the upper tube.

The expanded part of the upper tube is not the top of the tube where the dipstick rests, but rather, the expanded part of the upper tube is what friction fits into the hole in the block. You insert the smaller end of the upper tube into the block from the inside until the expanded part gets to the hole. It will then wedge into the hole in the block.

You have to make sure that the bend in the upper tube is oriented correctly so as to not interfere with your manifolds or headers. Once the upper tube is installed in the hole in the block, the lower tube will insert into it. I'm not exactly sure how the lower tubes for use with a windage tray mount, as I've only installed the type of lower tube that bolts to the main cap. I've heard that the type used with windage trays can fall out, but I'm not sure about that.

Maybe someone with experience with those will chime in. Also, I thought I read somewhere that the type for use without windage trays can be modified for use with a windage tray so that it can be better secured by mounting it to the main cap. Again, I'm not sure about that. I'm sure that someone will chime in with some experience on that.
