I was told by a friend who has driven his ford p/up for 330,000 miles to consider carrying a spare belt and/or vac.pump for my p/up (2006 GMC 6.6 Lt. TD) is this a potential problem I should be concerned about? Plan to tow a good size 5 th wheel tlr. in near future, n would like to be prepared if this is a concern. thanx

your pickup has hydro boost it uses the pressure of hydraulic fluid to assist you in breaking you should not have any problems at all with this system. maybe a few small leaks thats about it i have a 01 duramax 6.6 and have not ever incounter such a issue that your friend speaks of. one time the steering was difficult to move but it was -10 below and i think i had a little moisture in the p/s system i just let the truck warm up a little while before driving and it worked fine.

Your friend has a completely different engine than you do also. Don't know why he would say that, never seen a vacuum problem on a Powerstroke before. I would suggest you tell your friend with the Ford to make sure he has an extra set of fuel injectors, oil rail o-rings, and a cam position sensor in his glove box as well. Because all of these will leave him stranded on the side of the road with the Ford diesels. All diesels have their problems, if it is not giving you any problem, don't worry about it.

In a gasoline car, the throttle controls the amount of air to the cylinders with the throttle plate, so if you're not on the throttle there is less air available to the engine resulting in higher vacuum. There is no air restriction such as a throttle plate on a diesel, air is pulled straight into the cylinders. So there is no vacuum available for any component that may need it without a mechanical or electric pump.

The diesel engine has no air restriction in the manifold and therefor creates no or very little "low air pressure "
I wonder why you don't have a hydro-boost system in the truck (that is hydraulic boosted brake assist) they give much better breaking.
