DIY: Coolingmist 2.3G tank mount upgrade
This is what you'll end up with.
![]() ![]() Hardware you'll need for the tank 'holder'/Frame: 2x: 1/4"-20 x 1/4" Bolts (for nuts on back of tank) 2x: 1/4" Lock washers 2x: 1" x 36" x 1/16" thick: Angle Bar - $5.40 each 1x: 1" x 36" x 1/16" thick: Flat Bar - $7.00 each (coulnd't find 1/16" thick) Hardware you'll need for the brackets/mounting: 2x: 3x3in BRACKETS - $9.98 4 pack 4x: U Type Speed Nuts - $.92 2 pack 4x: 1/8" or 1/4" length bolts that match Speed Nuts. Tools You'll Need: Hacksaw, Dremel, cut-off wheel for metal, etc. (a Tool to cut Aluminum & Stainless Steal.). Something to sand rough metal edges smooth. Rivet Gun & Rivets. Drill & bits to match Rivet & Bolt sizes. Racket & sockets to match selected bolts. INSTRUCTIONS: 1. The measuring & cutting: To measure I simply put the tank into an angled aluminum piece and used a pencil to mark the length. You'll need 5 angled pieces. 1x: Front, 2x: bottom, 2x: sides And 1x: Flat piece for the tank to bolt to. Cut the pieces to length & sand any rough edges smooth. 2. Drilling & Applying Rivets: Next drill holes for the rivets. You'll be connecting at 6 spots. Shown in Photo. ![]() 3. Measuring for tank bolt locations: Put the tank in the frame. Mark where you'll need to drill the flat aluminum piece to line up with the nuts in the tank. Drill the holes. ![]() ![]() 4. Measuring for L bracket mounting points: With the tank in the frame, hold it in the trunk above the Amp. Then hold the L brackets on each side. Mark the L brackets and the bottom part of the aluminum frame for where the bolts would go. Drill the holes! Cut the L brackets to length & sand down rough edges. ![]() ![]() Now you can secure the tank to the frame & the L brackets in the car! ![]() So much more room than the way it comes from Coolingmist! ![]() I'm sure there could be a few solutions to help reduce the chances of Methanol dripping onto the AMP should you have a leak at the fitting. I'll leave that part to you. ![]() I'm not an expert. This is a 'Do it at your own risk' DIY. I don't guarantee ANYTHING in this DIY. I'm not responsible for ANY damage caused by following this DIY.

Very nicely done! I am starting to consider adding a meth system to go with my JB4 and this looks like a good way to do the reservoir to minimize the space it occupies.

Great idea
Great idea!!!!! I haven't decided yet how to make a more permanent but easy to remove if needed way of installing my tank...... Until now
Looks great I'll be doing this for sure. I might add a pan underneath to detect leaks And like the idea of your vent to atmosphere instead of trunk/car..... I'm pretty sure meth fumes is the reason I'm getting headliner fixed as we speak Thanks, R
