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

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?

You DON'T want to use hose clamps with high pressure fuel injection. It's not that it can't be done, but if they ever leak, or the hose gets brittle and cracks...major meltdown. You will have to flare the tube ends and use the proper fittings. You can get a threaded fuel filter at any auto parts store. Just get one for a late model factory fuel injected vehicle.

Can I run a solid line to the engine? or do I need something flexible? It will be a few feet of lines with several bends from the frame to the fuel-rail, so I think it will flex enough, but I'd like to do it right if there's a better way.

There should be enough flex in the line as long as it not secured too close together. It goes without saying your motor mounts have to be in good shape too.

Brand new Polyurethane mounts

Thanks for the help, I was afraid I'd have to buy some expensive braided lines, and my budget can't take much more abuse

AN fittings are your friend in this case, just remember that they use a single 37* flare. dont cheap out on the hose either, good steel braid hose is rated at 300psi min, not a problem with your 60 or so psi from the efi pump
