1976 Scorpion; Gold

- Start date
I was test driving it with no filters at all so I could peek around the carbs to see if there were any leaks from the new fuel hoses.

This would be overkill for the HVAC controls. It is sized for pneumatic wipers and pop-up headlights according to the description. I did a search for "heater control vacuum pump", and got quite a few hits. I think something like this would be more appropriate.
That looks nice but it would have to power the brakes also.

I can see if Denise from high school is still available. She could suck a golf ball through a garden hose.
More research on vacuum pumps. Probably a good idea to even out the brake boost response on the Scorpion. The feedback control loop keeps vacuum constant to ensure even braking feel at all times. They probably should have used this back then but the technology was not developed. Seems most cars these days have them, for example, any that shut the engine off unexpectedly.
The Jegs unit in post #81 is NOT a demand pump, but this one from Leed is. The pump assembly contains the vacuum sensor for the feedback loop and one-way valve to the booster and accessory vacuum chamber. It is a little on the big side, but there is plenty of room in the engine compartment on the driver's side.

Something else I wish I had 30 years ago. Hub stands. With only a single jack point on each side of the car, lifting all 4 wheels has always been a challenge. I already in the 1980s had to pound out the dents in the floor boards from some clown lifting the car from the footwells.
This will let me get all 4 wheels off to go to the wheel restoration shop. I made the mistake on my 308 sending only 2 wheels at a time and they came back slightly different colors.

Going through that effort would do an adjustable bias control.
Monit Brake Bias Adjusters
The New Monit Brake DialDesigned to work with all pedal boxes and balance bars, the new patent pending Monit Brake Bias Dial allows drivers to easily view, and adjust, the position that their brake bias is set too. Reset the display to ‘zero’ at their preferred position and confidently adjust...

Schematic of the brake power booster like on my car. Works a little different from the usual brake booster connected to the master cylinder in most cars. On my car it is connected to only the front brakes and is remote from the brake master cylinder. With equal master cylinder piston sizes, equal caliper piston sizes and equal disk sizes front and rear, the booster on my car gives near perfect braking bias.

I'm planning on putting the vacuum pump in place of the carbon canister. Power is close, there is an 8A circuit for an emission diverter valve that was in the area.
Thing is, the pump I want to use is 12A, so I'll only power the pump's relay from the 8A circuit (relay draws 0.7A) and power the pump itself from the battery connection on the starter solenoid (+).
