fuel pump

hi guys,
i am interested your opinions on installing a high pressure
fuel pump in the tank and regulating it down to about 6 psi.
think along the lines of a stock pump for an injected motor,
3/8's line from pump to regulators.
as with all fuel systems a power interupt or impact sensing
device should be incorperated into the electrical side.
i'm looking to build a reliable system that doesn't break
the bank and is somewhat stock looking.
thanks longarm
