Sharkbit Coupling Problems

[djohnson001]

So, I spent the money to use the fancy Sharkbite Couplings to fix my plumbing. I've finally gotten all of the couplings to be secure except for one. I have the coupling on, but with the location that it's at, I cannot physically apply enough force to get it to snap tight.

Are there any tricks to getting these things to snap tight when you can't push them that hard?
