Default Dual Fuel Feed

Well, I've got the Airdog II, and it looks pretty simple to setup a dual line feed - just a few more lines and another T fitting. What would be the benefit in me doing this, or would it just be a waste of my time? All opinions welcome.

Really no need for this.....
I had a club member do this with his truck and he gained zero from it on a dyno.

I dual fed my 175 ppump and IMO I think it is worth it. My truck ran much better than it did with just a single feed, the difference was mainly in the upper rpms.

Hammer, I don't have any dyno numbers to back this up but with the dual feed my 175 ppump ran way smoother up top. I think because the cam in the 175's doesnt allow much fill time the more fuel you can get in there the better. Also allowes for cooler fuel flow accorss the pump.

I did this Fuel pick up some years ago and so far it's one of the few mods that has worked without a flaw every since. https://www.dieselbombers.com/dodge-...pply-line.html

Thanks for the replys. If it helped out your pump it oughta do a little bit for my 160 pump. What'd ya just T off the main and remove that plug in the front?

160 and 175 pumps are exactly the same
