BAK MX4 Drain Tube Re-Route

I didn't like the track drain tubes hanging all the way down to the bed drain holes AND using up 2 of the 4 drain holes. Drilled a simple new exit. *Leave the tubes long and the water goes right out the bottom not running on any frame or body work. * I also enlarged the 4 existing drain holes along the front. I will be tying the ends of the tubes down with some tie down buttons and tie wraps so they aren’t flying around.

Nice. Is that the drain hose that came with your order? looks cleaner than what I got. Do you know what sice reducer and hose you used if you got it after the fact?

 

I was wondering the same thing as mine came with larger (accordian style) hoses.

These are reminiscent of what came when I had the “Toyota” cover on my 22

 

That was the supplied hose (July ‘23).
I’d swap for smooth hose. That accordion ‘wire loom’ style hose has a lot of flow resistance in the same diameter BUT it was larger? Might do better actually.

 

Was thinking today how a larger accordion style hose is supposed to fit thru those tiny bed drain holes? Did they use some sort of snap in adapter at the end to stick through the bed hole?

 

Took a drill bit and made it slightly bigger then squeezed it through
