Plus it will drop right on the pickup when the tank gets low, letting air back under the pickup foot.
QUOTE]
if an air bubble did drop down and not float and get to the pickup you would already be out of fuel and it wouldn't matter anyway
Not to argue, but look how far water carries air down a bucket of water. If you shoot the fuel straight down, you'll be making foam by aerating the fuel in the tank, and pointing it right at the pickup foot. None of that is productive to keeping air out of the system. Best idea is to gently return it to the bottom of the tank where it has the least opportunity to make bubbles out away from the pickup foot and the float. Don't know why this is such a point of contention -- as soon as you have a stream of fuel shooting through the air, it makes foam & bubbles, right??

Sounds spot on to me. I will be extending the return similar to Dan's.

Sort of a transition from chunky to smooth.

I'm pleased with the results. Well worth the cost and effort.

No, not really. Just evens out the pressure between the heads. Does nothing to increase volume.

For the average guy like me just making smaller Hp gains and just smoothing out the motor, a CCkit works fine. Th reg. return kit above is $549, My CC kit was $119 with the rubber HXP line. If youplan on upgrading to real high HPs go with the return kit, I was happy with the CC kit. I think I explained that right, if not chime in somebody.

EDIT: I think the full RR includes all new lines & fuel bowl delete option, where the CCK uses the stock lines & bowl. In practice, it's not a whole lot of difference. If you're building a high HP truck, the solution is obvious -- the "rest" of us can use the CCK and gain the same benefits.
