Looking for advice preferably from EVTs who have experience with pump testing. I recently went to a new department and nearly all of our brush trucks are failing pump tests and I’m inclined to believe that we are possibly doing something wrong. We can never seem to get our GPM to hit at the correct pressures. Most of these pumps are rated 250 GPM or less.

Just recently graduated lincoln tech for diesel technology and can’t find a job in my field of study to save my life just dead end interviews back to back is it always this hard or is it just me I’m also in the Memphis area if that helps

My truck has started making this noise. Not a mechanic so I wanted to get some feedback. It’s almost a high pitch buzzing noise
