Upgrading fuel system need recommendations

[sst1226]

Thanks for all your input.

I think for now I will leave the fuel system as is and put the 509 in and go from there. I figure the less I change in between engine swaps, the less amount of variables I will have to deal with should a problem arise. Not to mention the car had the same setup years ago with the exception that we used 2 holley blue pumps from each sump being fed into a "Y" into the #8 supply line running up to the front and the car went 9.80's with an iron headed 454. The only difference now is a have a single black pump.

Ron, the reason for 2 regulators was just as Bill had stated, the small feed holes. Figure it was better to use a regulator for each bowl rather than split that small feed hole 2 ways.

And yes I do have a seperate relay for the fuel pump as well as all the other electronics on the car.

Eventually I was thinking of going to a setup like Bob Gonier's with the regulator on the return side.

Bob Gonier, I was wondering:

What size supply and return lines do you run? I have heard of some guys not being able to reduce the fuel pressure enough with a small return line, although they may have been using a pump that flows crazy numbers.

Where did you route the return line? On my 69' there is a hole in the rear frame for the supply line to go through where it runs over the axle.
