Better yet, is there a thread here that shows how to replace the seals from a to z? If i Fck it up, i guess ill just end up spending a grand for a new one. So might as well try.

Complete factory instructions on disassembly, testing etc.

Just make sure to keep things clean on reassembly. Might be a good idea to use diesel or some light weight oil(engine oil might work) and assemble it under a "bath" of oil to keep dust out.

I've never done that, but I end up doing things wrong a lot...

 

Here's to doing things wrong a lot and I mean a lot

 

Thanks for the link. Good time to learn something new.

 

$400 core. might do this. with SnH maybe $700 total. Is this a good company?

 

Buy it from R&D IDI Performance - Home if you buy a new pump. Same price(approximately) and I trust him more than a random company.

 

Thanks for the link. Thats exactly what im looking for. Sold at "R&D IDI Performance is dedicated to bringing the Navistar/IH 6.9 and 7.3 diesel into the modern world "

 

Looks like i need to call them and tell them what i have here and what i need. lots of options.

Injection Pumps

 

what a badass site... i know where all my money is going in for the next 6months

 

I second R&D. I got my pump from there. Worth every penny.

 

I might be in luck. It looks like the leak is coming from either the injector, fuel line or the piece in between.

I doubt it's the fuel line. I've never had a bad fuel line NOT gush out diesel. It's definitely leaking from there. Do injectors leak? Or do they just go bad and not work and get glossed?

 

Replaced the 2 O rings. Still leaking. Very little and not enough to drip and hit the floor, but enough to get the engine wet with diesel.

What else could it be? The injector itself? That plastic cap?

 

Problem solved Replaced the black plastic part that covers the o rings

 

^^^^^ Return cap. Usually replaced as part of a complete return line kit R&R.

Good catch; must be a relief it's not the IP.

 

Damn it. It's not leaking from the injector/fuel line. But it's leaking from somewhere. It's gonna be the injector pump after all.
