Hi everyone,

I need a little help. I’m exchanging my old Coolant pressure and extension tanks on my Pantera from 1974. Bought new shining tanks from Hall Pantera.

Now removing the old tanks, I suddenly find a small extra hose on the pressure tank, approx on the middle of it. Just between the big inlet/outlet tubes. The small hose is on a small tube coming from the pressure tank. The small hose is not a wire, it a hose. Ive attached a picture of the old pressure tank. 

Now to the question, my new pressure tank from Hall Pantera doesn’t have a small tube to attached the small hose. 

So the questions are:

1) What is the hose doing there?

2) And what to do with the open small

A big thanks in advance.

Cheers
Chris

The new tank doesn't have any bung, only the two big in/outlets and of course the overflow bung in the top. See attached picture. 

Aha, so the small hose goes to the radiator in the front of the car? - I'll have to follow it and find out if there's a banjo fitting that I can close a you suggest. 

Perhaps I can take a picture and attached in a post in few minutes. Working on the car as we speak. :-)

Here’s a picture of my radiator - and it looks like there’s a small hose in the exact same size and looks as the one I removed from the old pressure tank. Here connected to the radiator via a banjo. 
Is this the same way it was done on yours?

(NB: I haven’t followed the hose from the engine room to see if it’s going to the front/radiator)

On my early car (s/n 1744) the small hose on the radiator goes to a fitting on the main radiator connection hose.  It has a small 'T' connection which I have always assumed was for bleeding / filling purposes.  The main pressure tank on my car had a temperature sensor in the middle port - doing what god knows.  I have since plugged that and chucked the sensor.
