I looked at the schematic on the Hilborn site.

If you eliminate the float bowl and just plumb the feed directly into the surge tank, convert the vent tube into the return line to the main tank and run a line from the vent to the main tank; it will work like mine does.

All other surge tank feed and return lines remain unchanged.

This will leave your surge tank full of fuel at near 0 psi and the main feed and returns on you Hilborn system unchanged.

The benefit is that your system won't be reliant on a needle and seat controlling the fuel level in your surge tank. It's one less thing to need adjustment or get hung up with a spec of dirt etc.
