Doing 6.0 lq4 swap into a 72 olds. Really close to getting it done, my only sticking point right now is the fuel system. The pump i got has a -6 an outgoing line. What are my options to rig this-6 to the stock lines or maybe new fuel rails and lines? Currently stock rails lines etc. and the truck intake.

 

You can buy an adapter off summit or jegs to adapt to stock fuel lines to whatever size hose if you want to run new lines. If you are using an external pump I would run all new lines.

Something like this: http://www.summitracing.com/parts/RUS-640850/

What year is your lq4? If its 99-02 then its return and there are 2 lines; 5/16 return and 3/8 feed. If its 03+ then there is a single 3/8 feed.

 

Thanks!, that adapter is exactly what I needed. That will be great because it will allow me to use the fuel regulator already on the fuel rail. It is a 2000, has a return.


Also all the lines are only a fuel years old installed -6 a few years ago when i did a 455 olds build. I can see the light at the end of the tunnel finally. One last order from summit and maybe on the road by christmas.
