Here's the stock air box from the van this motor came from. There was a bellow hanging off the elbow that we removed and will cap. Inner fender will be have some baffling to keep mud from directly hitting the air inlets but allow for outside air to be pulled in.
Fuel cell mount. Nothing fancy. There's a bracket on the other side that captures the center 3 bolts and is welded to the b-pillar cross bar. You can pull the 4 bolts on the flanges and slide the cell out.
