Question about my fuel regulator?

[myasylum]

I just got my fuel regulator today. It has one input and two outputs. I believe I only need one output to the carb?! What is the second one for? If I don't need it, would I just cap it?
Thanks!

If you don't use the second one just cap it...some guys use both outlets running fuel line to front and rear fuel bowls..

Hmmm... That is an idea! Is there a performance benefit to running it that way, or is it just cosmetic?

 

[daredevil]

only more performance if your car is built that thirsty.

Here's a thought, how about screwing in a pressure guage to the 2nd output port so you know what you're setting the regulator to.

it's for an EFI setup from the fuel rails
