Unless I am mistaken, Dean had some reproductions of those metal coolant pipes
made up. They were on his web site the last time that I checked.
Dean,
Do you still have those in stock?

Subject: Under carb coolant pipe: Repair or replace?
Listers,
Having finally replaced the starter motor on my
1600 '68 by dismantling it in place and feeding the
parts through the gap between frame and body
(Mike Young's idea), the roadster started up great.
The next day I drove it to get the oil changed and
drove to and from work. My wife was going to use
it the next day, so early that morning I checked
the fluids and started her up to warm the engine.
Soon I had liquid pouring on the garage floor...
It seemed to be coming from the hose than connects
the under carb pipe to the heater core. That figures,
because it got manhandled while working the tools
to remove the starter. That hose is NLA, so the
next weekend I got some generic 1/2" and
5/8" heater hose and a 1/2" inline connector.
The local Kragen didn't have a reducing coupler, so
I got the 1/2" inline from Orchard Supply Hardware.
Having replaced the hose, I flushed the radiator,
started her up again, but still it was leaking. I tried
putting an extra hose clip on, but that didn't help.
I tried to inspect the underside of the pipe where the
leak was with a mirror, but I couldn't get enough light
down there.
I started removing the connections for the under carb
pipe, got totally exhausted, and finally finished that today.
As expected, the pipe had developed a crack that
wasn't inside the hose.

I can't find this part on Rallye's site, is it available,
or should I have this one welded? (or simply JB
weld the hole?)
The heat shield that attaches to this pipe is
rather spotty with rust, does it get so hot that
a high temp paint is required, or will regular spray
paint do the trick to clean it up?
This makes two problems in a row, I think I'd better
change the tires to make sure the obligitory third
one isn't dangerous...
Regards to all,
