I recently completed an LS swap and have a few details to work out. First, i cannot fill up the gas tank. I have an aeromotive fuel tank for the fuel injection and have read how to install the rollover valve, but do not know where to mount it. Please comment.

Thanks 6850

 

Fixed your title.

To answer your question, anywhere that's higher than the filler tube.
The trunk opening lip would be the best likely spot.

 

Thanks for the reply. My thought is to mount the valve to the highest point of the undercarriage with a bracket I can fabricate. This point would be directly over the rear axle. I can do that, just don't know what others have done with an LS swap. Also, I do not know what you meant by the "trunk opening lip." I do not want it in the trunk. Please explain further if you wouldn't mind.

Much appreciated

 

Lol, what was I thinking, you don't want a gas vent inside the trunk. I also had high mounted fuel cell on the brain. Trunk opening lip is the part that the weatherstripping is on, but that's a moot point. The remote rollover vent wants to be at least as high as the highest point of the fill tube/gas cap. Are you able to get it that high from below?
