One cautionary note. Before you increase the size of your fuel intake
tubing to 1/2 inch, be sure that your fuel pumps are up to the job. I
had an issue several years ago with recurring fuel pump failures on my
generator. It turned out that the dealer had used 3/8 fuel hose to
the genset instead of the recommended 1/4 inch and that was enough
extra load to cause premature failure (it was pumping from a 320
gallon tank).

If the fuel pump is a positive displacement (which AFAIK they all are)
and the fuel flow is regulated (which it will be, by the injector pump),
then increasing the size of the piping will *reduce* the load on the pump.

I wonder if your problem was with the pressure regulator?
