That's pretty much what the GM/LS factory setup is. The pump, regulator, filter and return are all located back at the tank. Just a single line running forwards.

I figured I'd do something similar with mine but on steroids i.e single 1/2" line running forward and Bosch 044 pump. I reckon I'll loose out on a bit of fuel cooling but I think my tank is about 80L+ and with no exhaust system anywhere near it so it'll take some heating up. Plenty of airflow around the aluminum hard line running forward and probably only the heat soak to the injector rails to worry about.

e-clip, like Craig says, that reg is in a vulnerable spot. Might pay to make some sort of protective shield to go over it.

Cheers
