My overflow tank had rusted out so I bought the pair of new tanks for Hall.
Just swapping them in now and I noticed that my current setup used the sensor fitting on the swirl tank to attach to a bleed hose that goes underneath and up to the radiator (not a stock radiator).
The new tank doesn't have the fitting as you can see so I'm about to revert to stock it seems. Am I in for purge hell ? My radiator has a bleed valve on it but I will have to block off the other fitting that went to my current tank.
