I put a ls6 intake on my 6.0 this weekend. My truck is a 99 with the dual line fuel rail. I used a single line f-body rail on the ls6 intake. To hook up my fuel lines and still keep the return system, I used a corvette filter/regulator. Its bacically a filter with a built in return,my stock fuel lines just plugged into the back of it and I had to get a hardtube adapter on the outlet side to get it to hook up to the rail. Do you guys think this is ok, would you do any thing different? My tuner said this is why my truck doesnt run right, but I'm convinced it's his tune. Read my other post lq9 in and its a dog. Thanks guys

 

Do you have any pictures of how you hooked up the filter/regulator? Something does not sound right to me.

 

when we did the pinks setup. we used a vette regulator off the tank. car ran fine. that regulator goes by the tank and not at the front...

your tune deff is an issue. 42# are over kill for your setup
and your setup might be but i blame tune

 

Yeah.I put it at the tank on mt 69 camaro,and it works fine. I called Blake at Walker dyno today to set up an app. to let Gomer dyno tune the truck.I'm probably gonna put the filter/reg on the frame rail where mt existing filter is so I will just have 1 line going to the fuel rail.
