CJ, if this is the return line and not the pressure line, I discussed this in the "Vintage" section titled "handy little tip".
After time, the hose begins to break down and seep out fluid, sort of like a sponge. The return line is not under much pressure, and is likely held on to the metal pipes with hose clamps. The local parts house (AutoZone, Pep Boys etc) should have suitable hose to use as a replacement. DO NOT use heater hose as it is not designed to withstand pertolium products. I used crankcase ventilation hose. It's been several hundred miles since I repaired the hose, and not one bit of fluid has seeped through.
I just re-read the start of your post. This sounds like a low pressure line, since the fluid is being drawn to the pump. In that case the crankcase ventilation hose should work, provided your existing hose is held in place by hose clamps.
