Installing a vacuum operated pump for slide lube on my 96 vmax4 800. Sled is only used for 1000' radar runs. Where is a good source for full crankcase vacuum? Can I tee off of one of the fuel pump lines? Don't want to starve a fuel pump. Each carb has been modefied with added vacuum ports to sync carbs. One carb does not provide enough vacuum to pump all the way to the slides, only makes it part way. I know I can switch to electric. Sled was previously equipped with a vacuum set up but was removed before I got it.
a buddy who was doing vintage ice ovals just teed into the pulse line for his fuel pump for his lube pump as he was only using the cheap little mikuni universal single out pump.
