I think the banks instructions should include a paragraph suggesting an upgrade to an electric pump. I made the mistake of not following the instructions exactly in order when I installed my banks kit and ended up installing the lift pump after the exhaust manifold. That was bad enough.
Now that my engine's out of the truck, it's getting a nice low maintenance block-off plate instead of a mechanical lift pump.
