So I have really enjoyed the Bakflip MX4 on my 2018 Raptor, over the G2 installed on my 16 Lariat. The one issue I have is the drain tubes.
Most of the Gen2 Raptors have factory holes in the upper sidewalls of the bed for drainage. The supplied drain tube lines were a very tight fit, very long for upper sidewall fitment, and crimped badly.
For my setup, I chose to cut them significantly, but that left a pretty bad bend. Here's the before picture:

Here is everything I needed for the install.
The 90 elbows were bought at Lowes, 1/2" PEX and worked great.
1/2" TotalPond Vinyl Tubing at Amazon:

I ended up only using the black duct tape, did not need the pipe sealer tape.
Here's the "after" install pics. Need to wait for a rainy day to test, but pretty sure this is a much better solution.
