Just doing a big line kit won't hurt your truck, anything you can do to make it easier for your lift pump to move fuel will help. I would definitely do a big line kit over the drilled out banjo bolt kit, but the banjos aren't gonna hurt your truck either.
I don't know the website for the vulcan big fuel line kits, but this one is similar only from Glacier Diesel Performance. http://www.glacierdieselpower.com/product.asp?pf_id=9852MAX
The nice thing about these kits is that if you want a different lift pump down the road or an auxillary lift pump mounted on the frame rail, you can just splice one into the fuel line.
I think so. I don't know a whole lot of specs on the walbro. But from what I hear it is a really great system. My one complaint about their complete fuel system is that it is a bunch of seperate peices. Other than that I think it is most likely a great system and I'm sure you could make a bracket to tidy things up a bit.
