Injector leak test

Hey I was coming up the road and it sent 2343 and 559. The codes were a few seconds apart. Does this make sense?

This one too.

When is the last time you changed the spin on fuel filter? That 2343 is a plugged filter!!! What brand of filter are you using?

maybe an after-garbage branded filter sheered an o-ring at one point, and its now caught up into the fuel system somewhere?. - Just a wild guess.

This happens with the oil system when people use non-fleet-guard oil filters, and one sheers an o-ring. It works its way around inside the block for several months, eventually ending up in an oil cooling nozzle, destroying the entire engine.

Could your fuel pressure problems be a similar issue, but in the fuel system?.

Are we going to have to start telling people not to use after-garbage brand fuel filters too?.

I just changed the spin on filter less than 2 weeks ago. I use only fleetguard filters on my truck. I just changed the water separator yesterday. I’m at wits end lol never ever had this happen till that biodiesel fill up.

Do you think the regulator could be causing the problem?

Those spin on filters are 4 micron, it only takes a little bit of bad fuel to plug it up. Change it again.
