Need Help: How to run tonneau drainage tubes when bed is line-x'd.

As you can see in the picture, the little area where you'd run drainage tubes has been line-x'd. What's the best way for me to run drainage tubes in to those little slots?

Drill holes, cut out the line-x with a razor, something else?

 

Interested to know what others have done! I installed a bed rug before the tonneau and the drain tubes don’t go anywhere

 

My Tacoma collects lots of water in the bed-liner if I'm parked downhill and when I start to drive, it floods the street

My Tundra has factory spray or maybe dealer did it. It came with it when I bought new. I didn't know there were holes to drain water. Wonder if the holes were plugged after the spray.

Are the holes near the back where your tube is? I guess you can unplug them if you know the exact spot.

 

On mine, I tried to drill through the oval bed plugs. The liner (applied by Toyota, I assume at port by GST) pulled off of the plastic as soon as the bit took hold. I then just peeled it off the rest of the plastic plug and cleaned up the hole I drilled. Be careful not to go through and hit the back of the cab with the drill bit.

 

I just popped the plastic plugs out of the bed, and used a big enough drill bit to fit the drain tube through....the line x did come off the plastic, but being black to begin with it's really not that noticeable.

 

There are two locations you can drain from (see edited picture). The problem is those are now covered in line-x. If the truck bed hadn't been sprayed, those are just little plastic pieces that can easily be removed for drainage tubes.

So my options (as I see them) are to drill a hole and run the tubes through the hole or to use a razor blade and try to cut out the inserts. Anyone have any experience doing this?

 

This is where the drainage holes are.

 

I updated my post with a pic, I think your last 2 posts were in before my update. Hope the visual helps.

 

Use a "step Drill" that way you can get the desired size hole and not hit the cab

 

I used a piece of scrap wood and an assistant to hold it in place to protect mine.

 

It’s just a rubber coating on a piece of rubber. Not solid whatsoever. Step drill through it.

 

This. The linex will peel off. They're just rubber/plastic inserts. Can buy new ones cheap if you need to.

 

There is a hole on the bedside just to the right of your picture up high. I used a piece of red tubing that came with a harbor freight transfer pump and put it through there. Saw idea online somewhere and it works so far. I have an mx4 bakflip.

 

Would you know by chance what the name of those things are? I am currently looking for the part from Toyota.

 

Why not just run the tube through the already existing hole above your bed cleat, right below the clamp nearest the top of the hose? This is what I did, keeps the hose short and dont have to worry about snagging it on something if you put something in the corner there.

 

This is what I did. Very clean and worked great. I forget what these fittings are called, I *think* it was a 1/2 inch to 3/4 inch fitting. There are threads on the 3/4 inch side, so when I drilled a 3/4 in hole through the rhino liner and plastic cap, the fitting screwed in perfectly and is nice and snug. Looks clean and works great, I just need to paint them black now lol

 

Found it, I think this was the exact one I got, just take in your tube and make sure to find one that fits the barbed end, and use the right sized drill bit for the threaded end, it will screw in nicely

 

No pic of my truck because I rode my bike to work, but I circled the hole I'm talking about and the blue x is where you can cut the excess tubing.

 

I bought two new plugs so I would have fresh ones if I pulled the TC off for some reason.

Drilled holes in the originals. I used risers from sprinkler heads and grey PVC nuts from the electrical department. There is one inside and one outside of the plug. Had to dremel the the hole on the inside one to get it around the bend.

I spray painted everything with rattle can bed liner spray over primer. Like mentioned above, it fell off the plug when I reinstalled.

Edit: You can see little bits of the paint left on the plug (I hadn't noticed until now). Also, I would expect you can cut around the edge of the plug and pop it out with a screwdriver... mine came from the port with no bedliner on the plugs.

 

I chose the route I did instead of those holes as I would have to drill them out to fit the tube. Also I am not sure how the finish is 'inside' the bed and didn't want to dump water in there all winter long. Someone that has gone that route could probably educate both of us on this.

 

I used them without drilling. Just pinch the end of the hose a bit to get the diameter down,and stick it in there, if its the ribbed hose like mine, it should go in no problem. I have 0 issues, water goes right outside. I tested it with a bottle of water. Save yourself the trouble and having a way longer hose that might get pinched if you put stuff down there.

 

Do not use the existing hole in the upper side wall of the bed as MadMax suggests - as it is not clear where the water could possibly collect in the frame/body. See figures 11a/11b provided in the link below. The aforementioned figures provide a depiction of the proper way to install drainage tubes in the Tundra beds, without or with the Toyota plastic Bed-liner (respectively), as instructed by Toyota (of Canada) in their installation instructions. Good luck.

The fact that you think this could possibly drain into the frame makes me doubt your advice..... A lot.

 

@GODZILLA Well alrighty then.

I used the words, “could possibly collect in the frame/body.”

I assume that you are a mechanical engineer that not only understands corrosion and its affects on materials, but as how to protect them or avoid water and other particle intrusion altogether.

So then it can be assumed you know exactly where the moisture could go and thus not result in damage (I don’t)? It can therefore also be assumed that you also have seen the Toyota drawings for the bed and know how it was designed to drain (I haven’t), and furthermore you know the materials and coatings that were used to protect the area (I don’t)? You must also know that the hole in the bed side wall was put there to serve as the drain, and not for manufacturing purposes (I don't)? Since you are so smart (Lol) in these areas, you doubt the integrity of the actual Toyota installation procedure link that I provided too, right? Actually, I doubt your ability to think critically….…”a lot”. Arrogant twit.

 

Well, a chemical engineer would probably know more about corrosion than a structural. Perhaps you should consult one?

You didn't quote Toyota... you quoted Toyot-eh of Canad-eh.

Jokes aside, it's an exposed hole on the exterior of the truck. Common sense would point toward the fact that if water intrusion could be detrimental here, then it's a design flaw from day one and we are all boned.

I don't need technical drawings to know that a hole in the sheet metal on the side of the bed doesn't drain into the frame. I stand by my previous assessment that you entertaining that possibility draws into question your sense; common or otherwise.

 

An engineer who knows everything... while also stating they don't know... color me surprised.

 

You obviously know nothing about engineering. Chemical engineers are concerned mainly with chemical processes for maximizing product output, and perhaps chemical plant design. Mechanical engineers, like myself are responsible mechanical design, including corrosion concerns. You know nothing. And if you don’t trust Toyotas proven instruction, I doubt your ability to think critically……..a lot. Cretin.

 

5 whole posts before you had to tell everyone you're an engineer. That's gotta be a record.

 

You don’t get it, engineers are problem solvers. We do not guess we are on the side of caution. If Toyota, the people that designed this product, tell you how to do something correctly, why would you do it another way that you are unsure of?

 

Well, you sound like you’re a teenager. What makes you so smart? I think someone here is a teenager and that doesn’t like to be shown that they’re wrong. I would guess you don’t own a tundra nor even have a drivers license either. I doubt your ability to critically think……A lot. Lol
