Thanks I was thinking about it last night and maybe one of the clips on the top of the fuel tank that hold the soft line in place was pinching that line. I'll hook it up again and spin the soft fuel line around like you have it and log again.

Here is how I had the line bent. If it’s not the new fuel line I guess I could of been punching the flexible fuel line coming off the fuel tank. But don’t believe that’s it. If you logs come back fine. I’ll dig into it deeper.

You could be 100% right. Because like I said the way I bent the line wasn’t quite like yours. I didn’t realize you spun the line from the tank around 180 degrees. just wanted to let you know. Mine was being pinched or blocked somewhere.

Confirmed at lunch that the line was causing a restriction. I removed it and just plug the fuel lines back into there stock spot and my fuel trims went back to the way it was before. I'm going to go with the DXS fitting that is straight instead. I never had a restriction with the Russell fitting that where straight. So I'm going to go back to something like that.

Have you logged you fuel trims after adding this fuel line. After my Russell fittings failed I decided to use this line. But I didn't from memory remember you flipped the fitting coming from the tank. So my sensor it hanging out over the drive shaft. But it shouldn't flow much different than how you have it set up. I've been dialing in my spark since I already had my MAF and VE fueling dialed in pretty good. After the only thing I did to the truck last night was I added that fuel line. Now under WOT my fuel trims read much leaner. At idol and cruising it's fine but I think it's causing a bottle neck at WOT. My MAF error went from -1 to -2 to 8 to 10 and the wideband confirms it. I'm usually around .86 lambda and before I noticed it was lean I was at .95. Not good for WOT I'm going to go out and take it off a log again and see if it goes back to the way it was be for.

You lucky they only charged you 35. I had the same thing happen to my clamp when I did my headers about 2 months ago. I had too cut my clamp off. The Stealership charged me 56 bucks for the 3.5" clamp for my 6.2!!!!!!!!

You need to remove the Flex Fuel Sensor part. It's just a rear line. Here you go https://www.carid.com/acdelco/gm-original-equipment-front-fuel-supply-hose-mpn-23171534.html

Just wanted to update this thread. Don't use the Russell fittings that I originally used. (the blue colored fitting). They will FAIL, mine did after two years of being on the truck. This weekend I went to unhook my boat for the truck and it would hardly run. When I opened the drivers side door it sounded like a shower under my truck. When I cycled the key to the on position but didn't start it. I was spraying 40 psi of fuel on to the ground. Luckily I wasn't running E85 at the time so I was able to just unhook the sensor and plumb the stock ones back together. Use the DSX fitting or try the fuel line above. I'm going to try that one the bent fuel line. It looks OEM

It's right behind the main muffler, maybe 6" form it. You can't miss it if you just crawl up under there and look.

I have headers with no cats, then magnaflow 12909 3.5 in and 3.5 out. I cut the flapper valve out as soon as I tuned out the AFM years ago. I just cut the rear resonator off myself and left it dumped over the rear axle. I find this is a really good combo with lots of volume at WOT but quiet at cruising speed with no drone. Before I had headers. I had the 12909 muffler, no flapper valve and the rear resonator cut off. This was only slightly louder than stock with this muffler but much deeper. But I knew I was adding headers with a catless Y pipe later. And knew from my last truck that would wake it up alot. The stock Y pipe has three cats in it. This makes it to quiet.

2.5 leveling kit and 1-1/2" body lift. Vision rockers 22x12 with -51 offset. 33" tires. Little man likes to act like he's driving dad's truck.

Just did this last weekend on my 2014 L86 and I left the stock wires. They don't hit anywhere.

Its was Blake at Avid Speed But I have no experience with him.

Well that kinda sucks. He did a good job on my LT/DI Sorry man. He did mention he had a friend that has a big shop the tunes alot of DI stuff. I can look back at my e-mail and see who he suggested. The only reason I know this is because when I went to him for the tune. He basically told me the same thing but he had already answered a bunch of question while I was diagnosing my lifter failure before I ever paid him a dime to tune it. I told him he was so helpful I trusted him the most and still wanted him to tune it.

https://atomicfabandperformance.com/ He is a very respected tuner over on Performancetrucks.net He tuned my L86 have I did cam and heads and knock it out of the park. I never had to wait more than 24 hours for my new tune after I sent him a log. Most of the time it was less than 12 hours. His customer service was so good that after I got the truck together and running on a Friday night. I sent him my first log at 8:00pm Friday night and had the first revision Saturday morning when I woke up.
