Anyone made their own a/c hoses?

Good service....
Can you remind me if there are rubber portions to the lines that run inside the car to and from the evaporator?

Yes, there are rubber lines inside the car between the expansion valve and the firewall.

I've been thinking of buying this kit.

From website
A "cool" way to plumb your ride for A/C--Vintage Air E-Z Clip refrigerant hose kits are easy and universal! The complete process from fabricating to crimping can be done by yourself in your own garage. This rugged, lightweight hose has a unique smaller diameter that allows tighter radius bends and a cleaner looking install. And, assembly of the hose and nickel-plated O-ring fittings is easy with the included E-Z cages and clips. Finally, a simpler, better way to route your air conditioning: Vintage Air E-Z Clip universal refrigerant hose kits.

I cleaned out the metal hoses and took them too a local hydraulic hose shop and they replaced the rubber with barrier hose and crimped the ends for me. Cost me $85 and about 45 minutes of my time. I expected to drop them off and have to come back but they did it right then and there!

I did a full R134a conversion on my 89 325i last summer including compressor, expansion valve, drier, switch and condenser. I replaced only one hose I believe on account of the others were over a hundred dollars each, only available as BMW authentic parts. The system leaks out over a week or so and the dye/sniffer didn't help. I'll be pulling the motor soon and this will be the time to replace more lines.

Always game to tool up, I see very nice Mastercool crimpers being sold for the price of one of the three hoses I need to make. Has anyone gone this route?

Can the hard portions or the lines be re-used, with the appropriate crimps?
