Do I need to run the Wix 33737 Fuel pressure regulator and filter. I cant seem to find online if this motor is return-less style or not. I have a take-out motor from spaulding auto and currently there are two fuel lines going up to motor one connects to the rail. The other is left open right by the rail. Thanks. Attached Images
