Does anyone know how many feet of heater hose (both sizes) are used in a 1951 Buick Special?
Thanks,Toolman

Here is the real deal

Hello everybody.I have conected the watertubes as the pic in
your forum fo a 54 super convertible.Now i dont have any warm,
not from heater,not from defrost.I wonder if the man have put
the hoses in right places?Before when i did it my way the warm
was not bad.
Tell me if i am wrong. Stubbe in Sweden.
I will try to put my hoses as they were before,whit a tube on
clear plastic,and look at how the water runs the same as i did
for years ago.:shifter::waving:

Stubbie, could it be he didn't burp the lines, and there is an air pocket?:confused:
