I was wondering if I can use my carburated stainless tank to feed an LS1 in my 69 camaro.I will be running a carb for now but when I convert to fuel injection will I have to replace my tank????

you will need to have it modified with internal baffles and preforably an in-tank fuel pump

even if I will only use the car as a street car I still need to baffle the tank?? It just wont work with a standard tank and external pump??

it will work great when the tank is full... (external fuel pumps are a bit more noisy.. but with a nice exhause, who cares) but when you are down to the last 3 gallons it will cut out in long corners.. fuel will slosh away from the pickup and you will loose fuel pressure and the engine will cut out immediately.. then when you are outr of the corner it will spring back to life...

so yes it will work.. but not well when not full

So what your saying is that for street cruising and you dont let the fuel go below 1/4 tank I should be good to go?? Also do I have to install a return line for a 99 LS1?
thanks

return depends if you are running a referenced fuel pressure regulator.. if not then you could run a single feed and keep the pump and reg in the tank.. and im by no means saying its a good solution... but if you keep the tank atleast half full... or more it shouldny be a big issue...

but i dont get why you are so set on not doing it right.... its always cheaper to do it right the first time.. you are going to end up changing it anyway when it bugs you enough ....
