Flexible lines to engine, and Fuel-filter for high-pressure fuel system?

[Derek69SS]

I'm putting a '95 LT1 in my '69 Chevelle, and I'm new at this whole Fuel Injection thing.

I've bent up 3/8" supply and 1/4" return steel lines to run along the frame rail, but I don't know what to do when I get to the engine. It's pretty high pressure, compared to a carbed car, so I assume I can't just stick a neoprene hose with a clamp on each end... or would that be kosher?

Also, what can I use for a fuel filter if I can't use hoses and clamps?
