I still not sure how it was done, I came home one afternoon, and they were using the Jeep to run the milkers. That engine ran sort of rough on two cylinders.

Pulling vacuum?


Worked with an old guy whose side gig was septic pumping.

He had an old Ford cabover with a 390 engine, 1000+ gallon tank on it.

He had a pipe screwed into the intake and plumbed through a valve and a glass
jar into the tank. When he parked to do a tank,he opened the valve and the engine would idle a bit rough. (Two cylinders were pulling air from the tank instead of the carburetor) By the time he had his hoses rigged and the tank lid open he had plenty of vacuum. It kept a 3" line running fast until the tank was empty.


He had to watch the glass jar pretty close though. It was his full tank indicator.
Once the tank filled, it went in the jar, in seconds the jar filled and it was sucking
shìt into the engine.


Fords suck ass.
Smitty's sucked shìt.

Old times.

We had an Allis Chalmers CA tractor that had a petcock on the intake manifold that would adapt to our milker vacuum line with a hose. The vacuum from the intake would run two Surge milkers.
