Speaking of fuel lines...i just recently added a return and ran it over the top of the crossmember on the pass side in the engine bay. Well when I dropped the engine back in and bolted the headers up, well guess what? The #2 header pipe sat pretty much right on top of the return line. Let me tell you there wasn't a whole lot of wiggle room after eveything was installed. I was able to bend it out of the way some but I would've run it much closer along to the frame horns that hold the upper control arms if I had known there was going to be an issue. Just by way of information in the event anyone else is planning to install the same.
