Reply to "Brake question."

The brake hoses were original and still in good condition as is all the rubber on this car. Go figure. Yes I replaced them with stainless for safety. No black partials and the fluid even looked good.
I had to completely tear down the calipers. Everything ! It took me days to free the pistons. Heat, mouse milk and low air pressure. Why they were frozen escapes me as there was only a minor amount of corrosion at the piston bases and the square o ring type seals looked good but I replaced them. Piston dust boots were like new once cleaned. They made better rubber back then.
I purchased a rebuilt $31.00 Dorman master cyl. on line that I knew had the same internals but chose not to use the parts. Made in China on the box and my aluminum master seals looked fine and bench tested good. I am not a fan of anything from Chinese junk peddlers.
I know how to bleed brake systems and chased air bubbles for days and failed until I used the pressure bleeder. Again, high volume beyond what my foot or squirt oil can can provide. Master to caliper and caliper to master failed.
This car with 16,000 miles of use sat covered in a golf course maintenance shed for 18 years. No rust or mice just inactivity.
The interior leather has been the biggest issue as it dried out. Took some time but it's now looking good. Pure and warm neatsfoot oil with elbo grease.
I'm taking my time with this car doing system by system and learning along the way as I know next to nothing about Panters.
Lucky for me is this forum and that the car is all original and unmolested aside from the stereo hacks who had a go at it. Kids with electrical tape I suspect.
Next is the fuel system. I need the rubber hose coupling that goes from the fuel filler neck to the tank. Any ideas would help.
Also confused by the lack of any idle stop solenoid at the Holley carb for the A/C.
Doesn't appear there ever was one.
Thanks guys.
