External Electronic Fuel Pump for LS3 So I guess I need to get an external electronic pump and sending unit (the shop was suggesting this a few weeks back before) because CA laws state I need to use an OE style fuel tank for my 1978 Trans Am. So all tanks with internal fuel pumps are no-no. I need an electronic pump because I purchased an E-ROD connect & cruise LS3 engine and transmission.
Here is what Jeg's states on the product page:
"All that's needed to get a vehicle running with the engine controller are power and ground sources, a high-pressure fuel pump and an electric cooling fan. Chevrolet Performance recommends a 58-psi (400 kPa) fuel pump for the 5.3L and LS3 engines; and a 65-psi (450 kPa) fuel pump for the LSA."

On another forum I was suggest to use this:

Any other suggestions for external fuel pumps? I don't plan to do any drag racing.
