1980 F600. It's got hydraulic assist brakes. I'm not sure why I need vacuum reservoirs, but it's got a pair what look like thoroughly rusted-out foldgers coffee cans above the battery - with a lot of air leaking into the various vacuum lines that are connected.

Before I go back to the plumbing aisle at Home Depot, does anyone know where I can get a pair of vacuum reservoirs that might hook right up without drilling holes, brazing, silicone, and time time time?

 

Ford cars from the late 60s/early70s often had the "coffee can" vacuum reservoirs in several sizes. try a few junk yards. Also, Fords with hidden headlamps had some nice stout vacuum reservoirs, but they were a different style.

 

Oh boy I hope you have your crying towel your going to need it.

To replace the old hydravac boosters is very expensive it sounds like you have a blown or ripped diaphram in one of them.

Good Luck
