Low ICP after Injector removal/replacement
I had the lowest O-Ring (the white one) on my #4 injector to blow. After replacing the O-rings/Copper on the injector and cleaning the injector and bore hole, we replaced the injector and now she wont start.
I'm only getting 299 psi on my ICP with my livewire.
We replaced the standpipe oil tube (crankcase to head) when we reinstalled the HPOP rail but we didn't replace the dummy tube because we didn't remove it.
She would crank before this happened, even with the injector blowing fuel into the cylinder.
Question: Does anyone know if it is possible to screw up the installation of this standpipe tube? i.e. can the plastic back-up ring not compress properly? The whole standpipe was dipped in a gallon jug of T6 Rotella before we installed her. If not, what could be the problem with my low HPOP?
Also, Is it necessary to replace the internal o-ring at the top of the injector (where the HPOP Rail nipple slides into the injector) when removing/reinstalling the oil rail? We didn't but the injectors are fresh off a rebuild from Warren Diesel so I didn't think that was necessary.
