If your not boosting just leave the port open. My preference is closer to tank and shorter return line.I am just at the process of getting my tank ready for assembly and my bypass regulator also has a vacuum port on it that goes to the manifold. Where would you guys mount this type - Close to the tank with a long vacuum line or in the engine bay with a long fuel line return? Or do I just block off the vacuum port?

Didn't know you can leave the port open. My thoughts initially were to mount it close to the tank for a shorter fuel return - much cleaner plus that much more chance of a vapor lock situation eliminated. Thx guysI'm doing an LSA swap in my 68 and will be using a boost referenced regulator. Mine's going to be under the hood similar to this.
If you're going to be NA, I'd just leave the port open and run it close to your tank.
Jeff, I really like the way you did this, I may do the same. : )I mounted mine on the passengers side rear frame rail up high to clear my rear sway bar. Its a little tight and I had to use a couple 90s but I wanted it on that side so I could run the new hose in the stock location. Might be better a little lower if there is room.
It's the same either way.Didn't pay attention to the forum this was in. Won't be much use on an LS sorry guys.
