Blew a high pressure oil line on a 6.0 yesterday at 4pm

I was finishing up a road call near Springfield when the truck just started missing and died. Found the HPOP line had cracked right at the fitting, dumping oil everywhere. Had to have a buddy bring me a spare line and 4 quarts of oil to get it going again. Anyone else keep a spare HPOP line in their service truck or am I just paranoid now?

Did you check the fitting itself for any galling or damage before you put the new line on? A lot of times that crack happens because the o-ring surface is messed up from an over-torqued fitting. I've seen guys slap a new line on without cleaning that surface and blow another one a week later. Also, were you running a stock HPOP or a modified one?

WAIT hold on, I gotta push back a little on that. Checking the fitting is ALWAYS smart but I think the HPOP is actually the bigger player here. I was running a stock HPOP on my 7.3 and cracked TWO lines before I realized the stock pump was putting out way higher pulse pressure than it should have at high RPMs. Galling on the fitting can do it too for sure, but in my experience the pumping volume and pressure spikes from a tired or modified HPOP cause more cracks than a dirty o-ring surface.
