I can't stand that way the heater hoses just lay across the engine. I thought I'd seen a few before but does anyone have some pictures of a home made hard line conversion. I thought I saw one that followed the outline of the aprons.

Don't remember exact years, but a lot of the late 80s, early 90s 5.0 Fords have a hard line setup that runs straight back between valve cover and intake.

You could fabricate them using copper pipe and elbows from your hardware store. My heater core uses 1/2" copper pipe, and standard fittings will fit. In fact, I had to cut one nipple off and glue on an elbow and a short straight section so I could attach my hose.

I shifted the engine rearward 1/2" which prevented me from hooking a hose to the nipple. So I cut it off and glued on a 90' elbow with JB Weld. Off that I ran a 6" piece of pipe to get where I could easily access it and install a hose clamp.

I originally tried soldering the elbow on, but that was a dismal failure. I have not figured out how to properly solder, and working close to the firewall in cramped quarters complicated matters. I read where JB will sustain something like 300', so I figured it should work in a cooling system that won't see more than maybe 220.

So far, so good.

You could completely fab a setup using 90's and 45's and have a decent setup. You could cover it with nylon split loom for a neat appearance. Anything but nylon will melt, so be particular!

Of course, somewhere you must have a rubber section to absorb engine movement...

Thanks for the input, I like the 5.0 hard lines. I might just need to fab something from scratch. I'd love to hide them somehow. May be run them under the headers...?...
Not sure about the clearance or (temp issues?).

Steve, how did you bubble flare the ends of the SS tubing? so the rubber would stay on when clamped? is there a tool for this or is it a DIY tool you made?

I always heard that JB weld had a problem with antifreeze. I take it you have experienced no issues.
I knew it was too good to be true! :)

I haven't gotten any significant time on the system, yet. I've just started it up a few times and let the fans cycle a few times to verify their operation. Through all of that, no problems. Only time will tell if this was a huge mistake.

I repaired a '96 Ranger 4X4 radiator with JB Weld and the last I saw it, it had been going for 4 years. That was a plastic tanked, aluminum radiator with repairs on both materials. It was a roll over that I was just playing with until I was offered a good price.

This is what I used on my car and it worked nicely. I went to the auto parts shop and they let me look through their formed small diameter hoses and I was able to find something that worked for the 90 degree bends at the firewall. Hope to use them again on the new engine.
