Alturnative Fuel pick up

I have also seen this approach, plumbing into a curved aftermarket fuel neck, utilized to serve as a fuel return point for EFI applications.

I have been using this approach for the fuel pickup for quite some time. I am using a 1/2" pickup line. The only downside is that filling goes a bit slower.

Good point, EH. A stock size pickup line all the way to the carb limits horsepower to about 400-450 continuous flywheel bhp, no matter how much potential is there. The stock OD is simply too small to flow enough fuel (with a carburetor. EFI with 8X the fuel pressure may give slightly more max BHP.) Note this is not 'momentary' horsepower as in passing, etc.

That's a 1/2 inch o.d. 3/8 i.d., I can not tell any difference when filling the tank.The sock is the first filer, then a before pump and after pump filters total of three, that's on -6 lines.but it could step up to -8, I have run this set up on my car for (and I can't remember exactly) for about 18 years.( I know I was still married to my first nightmare)
