The electric vacuum pump for my brake booster I ordered just arrived but I am not sure where to install it. I have a 68 charger. Has anyone ever used one and if so, where have you installed it? Anyone ever ran it all the way to the trunk. I don't see why that would not work? The pump is rather large, around 7 X 7 X 4 so space is tight under the hood. I could possibly mount it between the radiator and grill.
