Aaron do you know any place that makes a silicon vac line kit for us I seen them once but cant find them anymore forgot where it was. I am in dire need of swapping mine out the stock ones are so hard and brittle the snap like pretzels and I think it is the cause of the poor idle (hunting idle) the sudden leaning out in third and fourth and the gas smell. I think a vac line somewhere after the injectors is cracked and or missing and when boost is held at steady pressure like in third and fourth boost is escaping and along with it some fuel there for running lean and gas smell. I know what you are thinking secondary fuel rail pulse damperner and no its not that. Checked and rechecked it like a million times. I carry a fire extingisher just in case rather be safe than sorry.

Also I know you have a fuel pump already but what kind if you say walbro 255lph do like I am going to and ditch that hunker and get a holley or bbk. I heard some pretty bad stuff happening to guys because of that pump.
