I made a video of modifying an lz4/9 fuel rail for what I hope is more flow, and lower injector DC.

It all fits under an lz4 upper no problem. Now there are two test ports.
After pressure testing I cleaned up the routing of the fuel lines and installed hose clamps. No leaks. I used a pair of 1/2 inch tube to 6an fittings.
Any questions feel free to ask.

Re: LZ9 fuel rail modifications
Laid the upper intake back on tonight and it all fits. The fitting on the rail near the tb just barely clears the neck of the upper intake but it does.
I figured this method was easier and cheaper than custom aftermarket fuel rails

Re: LZ9 fuel rail modifications
were you noticing fuel pressure issues in your logs?

I don't log fuel pressure. Unfortunately Don't have a sensor for that
