All About Brakes.

I have a 56 F100/460/c6/9in. The hole route. I just finished putting on rear disk to have 4 wheel disks brakes. My question is can I run a electric vacuum pump with a reserve vacuum tank or should I stay with the engine vacuum witch is about 15 lbs. Nothing is hooked up yet. Gary

15 INCHES is a good measurement, I'd think it would be fine but there are a lot of variables so give it a go.

It's not lbs, it's inches of mercury. 15 is better than 14, but not as good as 18-20, which is what the factory would have put together.
