What would I do to BS them? I've put a pile of injection lines on 12 valves.... it's not rocket science :lolly: They have been on the truck for about 12 passes, I snugged them up just like I always do and I even put the hold down bracket's on them. With my 13mm pump the fuel pulsing in the line's is so loud it almost sound's like the valves are rattling. I'm not looking for sympathy or saying that they are bad lines. I'm just trying to get info to see if it's a known problem with the .120 SS line's or something I did. I have never had a problem with their .093 SS line's. So I guess the question that I should have asked is if anyone else has had issue's with Scheid .120 SS injection line's. It's not like I'm going to beat Dan's azz the next time I see him. If there is alot of people having issue's with these particular line's I'll switch to something else. That's it plain and simple, just looking for feedback. This is an all out badazz Pro Street truck that I KNOW is high maintenance, not a daily driver at all. It work's a little over 6 seconds at a time. LMAO......Gary
