Making Heater Hose for 521 (L16 engine)

[Retired-04]

The heater hoses on my 1970 521 needed to be replaced.  The lower one seemed to be the worse.  I found an easy solution and posted some pictures on  http://s552.photobucket.com/user/seashellsbyshore1/library/521%20Datsun%20Heater%20Hose

 

To make the replacement Hoses I used a Gates 18457 heater hose, two 1/2" brass couplers, clamps, and a piece of 1/2" ID heater hose. 

To make the upper hose I cut two sections from the Gates 1847 and added a piece of 1/2" ID heater hose then coupled them together.

 

The lower hose was easier just cut on section from the Gates 1847.  No brass couplers required. 

 

The replacement hoses installed easily.  I didn't take a picture after the install, just posted photo's of how the sections of the 18457 hose were cut out.

So use hose clamps.

Looks like the heater hoses that I built for my 411. In the "How to" section. Ingenuity has no bounds!
