  • Can this be used as a permanent fix and drive with it being hooked up?

    No, this is just a diagnostic tool.

  • I have problems with my Cummins diesel It's a 2000 Ram 2500 it does when it sits up overnight and then try to start the morning it's very hard to start but once it starts it's good all day it starts Up Normally it just does it when it says except for a very lengthy time and I kind of feel that it's losing fuel pressure from the injectors to the fuel pump not sure what it is I replace the lift pump now I got a $300 Faust lift pump we've had the ECM and PCM each computer were reflashed

    That is a leakdown.  What you want to do there is to park the truck nose downhill one night,  then nose uphill one night.  If the truck hard starts with the nose downhill,  we know the leakdown is at the tank,  or lines from the fulcrum back.  If it hard starts with the nose uphill,  we know its closer to the engine.  Traditionally what we find is that the return lines are leaking.  Hard starts can be a nightmare to find.  With a little vacuum diagnosing you will track down your issue.
