why don't you mount the guage with remote hose at the pump? the
regulator stops pressure down to the preset level - if your regulator is
working correctly. the pump is what supplies the pressure. you might
have a bad pump, a fuel pickup that's blocked or ??. anyhow, start with
the pump. that's where it all originates. the "demand" for fuel at high
speed is nothtat big a demand with your set up. also, some fuel pumps
are designed to push and some are designed to pull. seee what you have.
