Yup!
If you have two ports to separate lines.
Your pic shows only one front port.

Re: residual valve 2 front lines

You only need to use one of those front outlets. You can plug off the other and use a single line with a single residual valve followed by a T downstream to the L & R sides. Fewer junctions equal less chance of leaks.

Do you have front disc brakes? If the master cylinder is higher than the brake calipers (ie on the firewall) you don't need a front residual valve at all. Gravity does its job for you.

It has two front ports. One is hidden out of sight on the bottom.

Re: residual valve 2 front lines

If you run two lines from the combination valve you will need two residual valves.

No need to run two. One line will suffice and you don't double your workload.

Re: residual valve 2 front lines

Don’t forget the need for a 10# valve for the back if you’re got drum brakes.

Re: residual valve 2 front lines

Going through the same process now. I am using my line lock for the tee. not going to be a drag car, just there to save the brake shoes while turning the tires into dust
