I used a hippo pump, had to cut the tank a bit but that doesn't matter.
Sealed it up with silicone, if rain gets in, well that's fine, rain is only about 20ppm.
Use a stanley knife to cut thru and you won't have bits. I use atlantic 2001 40mm hose from designation desihose.co.uk. lasts for years, I move my water about 100feet to my van
