Its in and running and driving but I have some bugs I need worked out before I can actually drive it.

What are those of you running LS motors in OBS trucks doing with the steam vent line? I need to plumb it somewhere.

Hey Greg, would you happen to have a picture of what you are talking about? For some reason I can't visualize it.

Over on LS1truck.com someone replied with the same thing with a pic.

On the OBS radiators (aftermarket that is) there is a nipple that is just below the cap on the tank that is capped off. I wonder if I can somehow use that. I dont want to pull the water pump off just to drill and tap that steam line if I can do it a different way.

What am I missing for the fuel gauge to read correctly? It is pegged past full and I know I only have about a 1/4 tank in there.

Just taking a stab at it but maybe the sending unit in the tank uses a different voltage range then what the LQ4 PCM is sending to the OBS gauge?
