I do not know this specific kit. But you should get longer lines now. 5ft is just not enough.
Edit: oups I know this kit: I got the same, but with 4 taps. Here is what I would have changed if I knew what I was doing
* ask them to have 10ft of tubing per line instead of 5.
* if you are doing a keezer, consider having shorter shanks. Mine are definitely too long and makes the keezer more busy than needed.
Things I changed and am very pleased with:
* the dual body taprite regulator is great. I use one body for the kegs, and the other one at 30psi to seal kegs and make sparkling water.
* upgrade with perlicks faucet: after reading a lot of post here on HBT, everyone was saying to just upgrade now instead of paying more money to do it later. I do not regret it as they work great.
