Your supposed to vacuum the system first, and hten fill it with 134-A, due to the fact that the gas and atmosphere mixing forms a highly combustable gas, however my 92 retro-fitted to accept 134-A was not vacuumed before it was pumped, and it works fine. Depends on who you ask really.

Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well-preserved body, but rather to skid in sideways, scotch in one hand, body thoroughly used up, totally worn out and screaming HOOOOYA !!!!!
