Hi, new to this forum, I have a 2000 GMC SIERAA Z71 4X4 WITH A 5.3 MOTOR, yesterday i had a dead battery so when I replaced it and fired it up i noticed a strong suction sound, the sound was coming from a broken plastic elbow that the other end of the fuel pressure regulator vacuum hose plugs into, my dilemma is that i cant find any parts/info on the broken plastic piece. please help fellas this truck is my money maker so i cant afford for it to be down.
also when i removed the hose from the fuel pressure regulator raw gas came out so i already replaced the regulator. thanks again!!
