Fuel pressure regulator question

I have a Holley fuel pressure regulator with 2 outputs. Can I block one off and just use the other? I dont see why not but thought Id double check here.
thanks

As far as I know you can plug one, but maybe it's designed for a return line? Maybe the model number will help so I can try to look it up and get some specs.

They are design to use with a return.
You can use it without, but the pressures won't be consistant. That would defeat the purpose.

Any of the above.

U can use it for a return, press gauge or supply another carb. U should retstrict the flow if u plan to run a return line. And don't use the liquid filled peanut gauges for pressure - eng comp heat will ruin any press readings.

Good luck,

I don't plan on running a return and have a pressure gauge to mount by the carb so will just block it off. In the specs it says its a non return type regulator so the pressure should be consistent just using one side.
This engine build has been an experience so far (not sure if its been a good or bad one). One thing Ive learned is that I,m the most disorganized
**** Ive ever seen. Every order I make from Summit or Jegs I forget a ****load of stuff I need.
Thanks for the help guys
