If I have the system evaccuated and change the o-rings and other parts in the Kragen kit. then I buy the $33 dollar Walmart kit, add the 134? Will it work?

If this old system has some r12 residue, will the new 134 eventually fail? It it does, can I just change the 134 again. How would I get all the r12 out without cahnging every part?
