Why not ..

During this whole ordeal and figuring out what I wanted I decided that I didn't want to crawl under the truck to let the air out of the tank and what's one more solenoid and button ??!!... It's just one of those things .. simple and works great

Must have add on to ANY kit!

I purchased this Electric Drain Valve Kit when i ordered my 2485 Nightmare Edition Horn Kit with Dual tank Spare Tire Delete and i am happy i did. This keeps me from having to get under the truck every week to drain my tanks. I have Dual tanks so i have this drain valve connected to both tanks via T connection. (Order kit WITH ELBOW and order an extra Elbow and T connection if using Dual tanks, Makes it much easier to connect) Let me tell you. Just hitting the "PURGE" button i wired up in the cab to drain the tanks turns some heads too! Sounds Awesome. I ran the drain line straight out the back and when the rock lights are on at night the "Purge spray" (Moisture) looks pretty sick. This is a MUST HAVE add on for your Tanks. Highly Recommend.
