Zderf,
Correct on the location of plumbing for the Accusump.
Mounting is planned for two flat vertical brackets welded to X frame. To these, two flat brackets at right angle to vertical brackets will mount the Accucump. This will alow Accucump and its mount brackets to be removable for engine pullout without cutting and rewelding any brackets.
I can't bolt through X frame directly as brake lines on the other side.
