Evap Canister Relocation

By zj

This install was done on a 2001 Ram and it only works with a body lift.

First off, remove the four bolts holding the whole assembly to the frame. Rest the cannisters on a piece of wood or something so the lines aren't stretching.

Mark a spot on the frame about 1 1/2" ahead of the line that passes thru the frame. Center puch the spot so your drillbit doesn't wander. Drill the hole with the 17/64" drill bit then tap out the hole. This tap size lets you re-use the stock bolts that held up the cannisters.

Take the 6" piece of steel and drill a 3/8" hole on each end about 1/2" from the end. Drill another 3/8" hole roughly 1" - 1 1/4" up from one of the holes.

Attach the bracket to the front of the cannister assembly with the 5/16" nut and bolt fingertight.Lift up the assembly and put one of the stock bolts thru the bottom hole on the rear mount of the cannister assembly. Tighten slightly. Hold the assembly level and mark where the bottom 2 holes on the front bracket will be on the frame.

Lower down the assembly again and center punch the 2 marks you just made.

Drill and tap these 2 holes the same as the first one you already did before.

Put the assembly back up and loose install all the bolts making sure you don't have any of the lines caught or pinched. Tighten everything up and it should look like this.

On my truck I gained almost 4" of clearance under the cannisters. Now any objects should hit the frame first.
