hey guys i have a question on how to rig up my fuel lines..

my current hook up is, i have a holley pusher pump back near the tank, with a stock mechanical pump on the motor..
the mech pump has a return line built in so no need for a fuel regulator.. but i don't think the mechanical fuel pump is giving my car enough gas, it acts like it starves for fuel sometimes

so what i want to do is get one of these PUMP

that one says no regulator required, but i had ordered it a while back and it only had a IN line and OUT line on it, don't i need a return line on the mech pump ??

sorry if i'm confusing some of you but i want to get this right
lemme just say what i want
i want to replace my stock mech pump with a performance one, but the performance pumps don't come with a return line on them, so how does that work??

below is a pic of my current pump where you can see 3 lines, in/out/return

 

The stock pump is plenty for at least 400 HP. I know, I have one that was on my 400 with big heads, XR282HR cam, 800 carb, etc. etc.

If your car is actually starving for fuel, it's something else.

What are the symptoms?

 

symptoms

i have a clear fuel filter, and at higher rpms, i see air bubbles (sometimes a lot)

and at high rpms it sometimes smells like burning popcorn
