Thanks FFDP

I haven't seen the dsxtuning kit, I knew about the CJtunes E85 kit. Seems like they are all 300 bucks. But for the gains I guess that really isn't to bad.

Another option is to go with all factory fuel lines from a flex fuel truck. The parts below cost me $155. It takes a couple hrs to install since you are basically replacing all the fuel lines from the tank to the fuel rail. The hard fuel line that connects to the fuel rail (2317153) takes the most time.

Here are the pns from my 2016 6.2 8 spd. The 6 and 8 spd trans use a different hard fuel line (23171537 fit my 2016 8 spd) that goes from the flex fuel sensor to the fuel rail.

Sensor 13577429
Sensor Clip 20967866
fuel line 23171537
fuel line 23171538
fuel line 20967834
fuel line 23158923

I'd suggest checking with a dealer to verify pns for your year truck.

I'd imagine these are different for each cab style and bed length though, yes?

I would suspect a couple of the pns for the hard lines could be different based on the truck configuration. The pns I listed were for a 2016 crew cab, short bed, 6.2 w/ 8 spd trans and 4x4.

Better and cheaper to buy the GM parts. And it is a easy install.

Do i need any special tools to disconnect the factory fuel lines. I've never done anything like this before with fuel lines. So I"m not sure what I'm getting into.

It will be for a 2014 6.2 with the 6l80. So I guess I need to figure out what fuel line goes around that trans.

Jonblarc7

and is there any reason I can't do it this way on my 6.2 instead of replacing all the fuel lines
