soooo everybody is telling him to change the beer lines but nobody explained why.
The beer needs to exit the tap at near atmospheric pressure to minimize foaming. That pressure reduction is *usually* provided by the friction of the interior walls of the beer lines. Bev tubing has a known friction coefficient. PVC tubing is slicker and does not have a published friction coeffecient, so you don't know how much line you need. If its all you have available, you can make it work, you just need an insane amount of tubing. Think 50 feet to start and adjust from there. Your described experience is virtually identical to what I experienced when setting up my kegging operation. 1/4" bev tubing, 1/4" hose barbs and foam city. Changed to 3/16 tubing, ran the calculator mentioned above and added 6 feet to the calculation because you can always cut the lines shorter, its been proven more difficult to cut them longer. As a side bonus, you CAN use 3/16 bev tubing on a 1/4" hose barb. Just dip the end of the tubing in boiling water for a moment and shove it on. Makes a near leak proof seal. The only drawback is it can't be pulled off, you need to cut it. Also added Perlick flow control taps. Don't feel dumb, we've all been there, its part of the charm of home brewing, like growing a beard. If you want a laugh PM me and I'll link you the forum history where I asked these exact same questions.
Oh, and I still have some *extra* 1/4" bev tubing if you need it

I use it for the co2 side of the plumbing.
