And then we would have top add a vacuum pump for them.
I had a friend whom did a vew gas to diesel conversions and had to add a vacuum pump.

This is a problem on my car at light load and running around 1 to 2 psi in lean burn. If I let off the gas and coast it takes me a awhile to get back into my lean burn 1psi+ part of the map. So I usually just touch the breaks to slow down for traffic while keeping the same amount of gas pedal input, but after a few times I lose my vacuum in my break booster. So I added a vacuum pump on a switch to instantly get my vacuum back to the break booster.
Sorry the pic is kinda dark?
