Fuel system requirements for TBI

What have any of you done differently to the fuel system to run a fuel injected engine (specifically a TBI 350). I was planning on keeping my existing sending unit that I just put into the new tank and also keep the new anodized aluminum fuel line. I was then going to use an electrical fuel pump. I have heard of people using the sending unit and pump from the OE engine, but I don't know if I can get or make a OE unit work in my oversize gas tank. Any opinons or personal experiences with a TBI swap would help. Thanks.

Re: Fuel system requirements for TBI

the pumps were put in the tank to cut down on noise, it does not have to be in the tank. you can mount a inline pump on the frame as low as possible ( these pumps are not good at pulling fuel uphill ). howell sells a pump for this setup, it is an OEM pump but I don't know the original application, it looks a lot like the mopar MPFI fuel pump.
good luck, jjc

Re: Fuel system requirements for TBI

The GM vehicles with fuel injection have fuel pumps in the gas tank with a couple of plastic baffles. The baffles are to keep fuel near the pump when the vehicle corners or when braking hard. I'm not positive, but Aero tanks (http://www.aerotanks.com) might offer a replacement tank that would include an electric fuel pump for either TPI or TBI, and a sending unit. The Aero tank might include the plastic baffles also, don't really know.
