So i have a Viar 480 compressor to fill my 3 gallon in the mail. My tank is mounted to the underside of my tool box in the bed. My question is: Should i mount the compressor to the bottom of the tool box, like the tank, or in the tool box. My concern of having it in the tool box is, will it have trouble getting clean cool air? and my worry of having it outside of the tool box is the elements.
Thanks a lot.
i think there is no problem with it if you put it inside ur tool box… many people here have it like that…
If you mount it outside the box, relocate the air intake filter in a dry place and it should be fine.
i had no problems at all with my compressor being mounted underneith my truck so under your tool box should be no problem…
Keep in mind … i also remounted my 480 inside my tool box and it vibrated the tool box like crazy…
I mounted my compressor on a piece of 10ga. sheet metal which was then mounted to the bottom of the tool box with a hunk of rubber between them. No vibration issues and I know it will stay cool.
My bed is covered with a diamond deck cover, so it’s also weather protected.
dunno but i love the shovel holder =D
If I have the tank mounted to a carpet covered piece of plywood (trunk install), can the compressor be mounted on the plywood as well and have the line run up? I’m slightly limited for height…
Sorry for the ignorance…I’m rather new to this all, but I’m trying to pick it up!
thats just fine, will work great, the reason they say to have the tank lower is so moistre doesent run bacfk into the compressor, just make sure to use a side port or top port for the compressor
Hmm…good to know. I appreciate the input. Also, one other minor question while I’m planning this all out. The solenoid valve…is there any problem with having that placed up closer to the splitter for the horns rather than back near the tank?
you want the solonoid as close to the horns as possible, i would run the splitter directly out of the solonoid if possible. my solonoid is connected to my k3…
Hmm…so there isn’t any problem keeping that 150psi in say 15ft of air line up to the valve? That’s why I thought it best to keep the valve close to the tank.
most air line should handle 150 PSI without a problem
Always use DOT-rated air line for peace of mind.
Any time you route air line through a hole in metal, remember to sleeve the air line and secure it, to keep it from chafing on the exposed hole that you passed the air line through.
Good to know 
On the subject of air lines…how might I figure out exactly what size line I need to get to replace the current lines that are with my system?
If you’re talking about air line, and are unsure - just cut a section of the line and go to a store that sells DOT airline to match it up. If buying online, you can usually do the same thing locally - just note what you’ve got before you order.
noted Would a place like Adv Auto carry the DOT line? Lowes maybe? I can’t seem to locate air line on either of their websites… 
Any custom shop will have it, namely street rod shops, custom truck shops, HORNBLASTERS, etc.
