30R9 fuel injection hose is commonly sold at Autozone, O'Reilly, Pepboys or any other auto parts store. They are NOT to be used inside the gas tank. 30R9's outer lining will literally melt inside your tank. You'll get low or no pressure at the rail, even though you could hear the pump running, this can happen in less than a week.
You'd want 30R10 submersible fuel hose, you can buy it from Napa or Carquest. It is not cheap, but you'd probably not want to do the same job twice.
Buy some fuel hose clamps also, worm clamps can easily destroy a hose.
Below is what happen if you use the wrong fuel hose and clamps, which caused no start, which cause the car to sit for over 4 years, while slowly killed the fuel pump in the process.
