Walbro pump and Stock tank, can it work?

[jiggityjoe87]

Well i've recently begun an lt1 swap into my 70' suburban and I am trying to get the fuel system thought out before hand. I've had a few different ideas that have crossed my mind and i'm looking to the forum for some advice. Keep in mind that I just bought a 95' z28 so I'm going to try and reuse the camaro's fuel lines, etc.

1st idea: keep the stock tank and buy a walbro in tank fuel pump while retaining the stock suburban gas gauge sending unit while having the return line routed into the gas filler neck. My only worry is that the stock tank wasn't designed with any baffling so I wasn't sure if i can run the tank low on gas without worrying about the pump being starved and burning up prematurely

2nd idea: use the 95' camaro gas tank with the stock pump sending unit etc. My only concern with this setup is that the Camaro tank is something like 12.5 gallons and I would like to keep a decent range between fillups (long roadtrips).

3rd idea: keep the stock suburban tank and have a low pressure external electric fuel pump mounted to the frame to supply fuel to the high pressure pump downstream therefore always having a supply of fuel. The only reason this comes to mind is because the previous owner of my burb installed a cheap auto parts store special electric pump between the tank and the current small block. I want to try and avoid this route because I don't want to hear the whine of the fuel pump all the time.



well evrybody mull these over for a minute and if you have a reality check in store for me please let me know because I only want to do this fuel system once and to have it last for 100k miles.
