I don't know if anyone else has/had this issue, but J took a long time to accept any type of pump pouch, then it took several variations to find what worked for him. Then I gradually moved him toward a more "normal" looking pouch instead of an ace bandage that looked like he had a big belly hanging under his shirt! LOL

Anyway, we have finally ended up with a wonderful conclusion to all the pumping craziness and pouch craziness.
J couldn't stand velcro, but I finally gave him no choice and told him I would pay him $5 or so to try it. Now he wears a simple fleece band around his belly. It velcros closed in the back and has two patches of velcro on the front, one over each hip.
The Dex receiver and his Ping both have velcro superglued to their backs (with a hole cut out so we can download his Ping for endo visits). He loves it! And so do I, no more playing find the Dexcom. :)

So just an idea to put out there hoping it might help someone else.

Oh, for the tubing, we wrap it around the pump and secure it with a touch of electrical tape at the left side of the front screen of the Ping. Works great, doesn't show up badly since it's black, and lasts for days at a time. And it's cheap :)

I discovered that for J, rounding off the edges of the velcro is essential - no sharp corners. He has two of the 2" wide pieces in the back of each belly band, seperated by a small space so the area is more flexible. And each piece that holds his Ping and Dex is also rounded.
Hope that helps someone :)
