      Server Slowness & Strange behavior   03/15/2018

      I'm aware of the server and the site speed being weird. Might find strange server error messages and other things happening randomly. What I do know is the hard drive is hitting 100% load randomly and driving the server load up high. Then for no reason, the hard drive returns back to normal loads and server load drops. I've got the hosting company watching this and attempting to find a solution. I apologize for the performance issues... Thanks for understanding...

Recommended Posts

Swapping a Cummins from a 97 Dodge dually into my truck.Does this engine have a vacuum pump on it so my power brakes will work?It came equipped with the hydro-boost power steering/brake comglomeration.

Yeah it has a vacuum pump, all 12v's do. The power brakes work off the power steering pump though.

I don't think the vacuum pump has enough capacity to support power brakes. it certainly doesn't have the line size for it. Perhaps with a decent vacuum reservoir, though I'm not sure what application you could steal one from.Much easier to convert your truck over to hydroboost.
