Looking for some advise on an aftermarket fuel regulator, looking to run E85 if that matters.

Anything better for the price?

 

Try searching fuel lab's product line.

 

Picked up the Fuel Lab 545 series regulator and 818 series filter.

Filter is quite large and I am having a difficult time finding a location to mount it where the brake lines do not get into the way.

Is there any benefit to running the regulator before or after the fuel rail?

 

...the benefit to running a fuel regulator before the fuel rail is an engine that won't work. As long as it's anywhere in the return line, it doesn't matter where, it won't make a difference.

You might try installing the filter near the gas tank instead, or using flexible fuel lines to mount it elsewhere.

 

Hmmm...

Kinda funny that all current honda's are made this way them.
