I replaced the fuel sending unit, ran all new braided lines did a pre and post lift pump, used a walbro frc 10 and did a ffm delete, the pump runs really really loud and I am not even getting fuel to the IP, please help!
Yes those two diamond shapes are the Navistar symbol, near the date code on the passenger side rear looks wierd? like they added material to the block all the GEP's I have seen did not look like this.
so now I am confused,I have square pre cups and had high flow oil pump?? it definately had a spacer between the pump and pick up with a long set of Gears...HHHMMMM????
Not to mention the 7.3 is an International motor!, the 6.5 is a Detroit diesel what do you see more of on the road???? that is why getting a military hummer take out motor or an optimizer is the way to go that is also an International motor!
