Go ahead and replace the hoses.
And do not use heater hose. I used that initially, but still had to replace them a few years down the road. The fuel vapors will harden the heater hose and cause it to crack, causing leaks.
The only 2 hoses I've ever seen that needed to be replaced are the long 1/2" hose and the 5/8" hose w/ 180 degree bend. The short 1-1/4" hose from the filler neck to the expansion tank typically is fine. (I've looked at over 10 cars in junk yards and on everyone of them this hose was fine.) The 1/2" & 5/8" hose can be bought at any NAPA store for around $1.25 per foot. Not bad, but not cheap. Make sure you get the fuel line grade hose.
I bought 5' of the 5/8" and 8' of the 1/2" hose when I did mine just to be on the safe side. To make the 180 degree bend you'll need a piece if 1/2" OD steel tubing (preferrably stainless) about 6" long. (Do not use copper tubing! The fuel will degrade the copper over time and could ruin your fuel system.) You can probably find a place that sells this (plumbing shop would be a good place to start) and they'll most likely be able to bend it for you. I used a bench mounted vise. Painfull and time consuming, but it worked. Once you have the tubing bent, just slide it in the 5/8" hose and hook it all up. It's pretty easy from there.
While you're at it, you might as well replace the 3/8" hose going to the hard fuel lines and to the carbs if they haven't been changed already.
Good luck and don't forget to drain the gas tank! It's amazing how heavy about 8 gallons of gas feels when it's sitting on your chest! Don't ask....
