When I first started with fuel injection I used an external pump and regulator in the front with a return line. But I keep having problems with the pumps getting hot and then the fuel would boil in the lines. I was picking up a lot of under hood heat and bringing it back the the fuel tank. I tried 3 different external pumps. I was also using a weld on sump which would uncover the pickup if the fuel got too low. I solved these problems by putting a fuel basket from a 99 to 02 F body. I got myself a new tank, then an adapter plate from Corvette Works. A little cutting and welding and the tank was ready for the fuel basket. This basket has a regulator built into it, so I only run a single fuel line to the front.
