Blazer tank install questions. Please help

[roughedup72]

Hey everybody, Its been a while since I've posted but I am in need of some advice. I have my truck torn to pieces and its in the paint shop. So hopefully some new pics will be added to this thread before long. My question though is. When you blazer tank users installed your tank what kind of lines or tubing did you use to feed the engine and did you run a return line. My in cab tank has a return and the blazer tank dont. So what should I do? My engine is nothing special at the moment but when I get done rebuilding the 5.7 vortec thats in my garage I hope to be around the 400 hp mark. (Key word hope) Which by then I will need an electric pump but for now the stocker should work fine. My main concern is should I run a return line or not? and where can I get fuel line tubing? I'd rather not run rubber hose but may have to as a last result. Thanks for your help.
