Injection Pump Problem....
I have a Turboed 7.3 and I don't know if the injection pumps are the same between the turbo and non turbo... Are they? then my next question if they are the same then could I easily put a 6.9 injection pump in there? Any place that I can buy a rebuilt injection pump for cheap? I seem to have diesel fuel all over it. haven't cleaned and checked it out but I am thinking that it can be the injection pump. the truck does have 205k miles on it now. the nozzles seem pretty clean so I don't think that they could be the problem. well considering that I do have a fuel leak I think that 15MPG is pretty impressive. that was my last tank driving 60 miles to and from work one way no traffic driving 55mph other way traffic stopping you to 0-15mph. what do you think?

Was the turbo factory installed......... what is the pump model #
92.5 E injectors and 5013 IP
94 TD G injectors and 5070 IP
Use the right pump your engine is a 92.5 Performance and emmisions engine. Look at the tag on the timing gear cover what date is punched out.

The tag says 4G005AA and 93 1/2. The leak is quite wierd. it is towards the front of the engine. I guess it is spewing fuel down the fron of the valve cover and down the oil pan. also fuel was found on the water pump. I checked the oil no fuel in there so it can't be coming out of the front gear seal? this is mind boggling.

This from an old post I saved........
Ok hear we go. I got in touch with Stanadyne Corp. and asked about our injectors, a topic that turns up often! Hear is the scoop.
"Although this is really a question for Navistar, I will provide you with some information.
There are three different injectors used in 6.9 & 7.3L engines - one for the 1984-1992 6.9's & 7.3's, one for the 1992 1/2 - 1994 engines that Navisatar referred to as the "P&E" (performance & emissions) engines and one for the 1994 turbocharged engines.
In reviewing the drawings I see that in addition to to different nozzle opening pressure for the injectors, there are a number of differences between the nozzles including:
different pintle diameters, pintle bore clearance, valve overlap length,valve extension etc. all which result in different valve lift vs flow characteristics and therefore result in the different injectors for the different engine applications."
Sincerely,
Mark Dionne

I would wipe up the fuel then slide a piece of cardboard under the IP and see if the leak comes from underneath, if the front then internal seals if the middle or rear the exterior entrances or the advance lever.
Go here to see the possible leak points.....snoop around on the gallery for good info too........

Found the problem... It was a bad injection line. Saw it dripping from 1 fitting at the injection pump. it was actually cracked and the fitting was cross-threaded. hopefully I get better fuel mileage. I found out my IP is a 5070 and it's 325 to rebuild from this guy in Indiana. wrote his number down somewhere. I need to find my nozzles. He said for $200 he would rebuild them and ship them back. I have 6 nozzles that are C and 2 that are G Stanadynes. The original 6 that were replaced with C are in a box somewhere. I am going to go crazy if I don't find them cause he said that it would be 240 to ship me some G model nozzles. I am glad that my IP is good. Somewhere along the lines it has been rebuilt because it does have a rebuild plate on in instead of the original Stanadyne plate on it. Thank god for weekends or my truck would be in trouble. I also had a problem with the switch. It went bad and blew out all the bulbs in the corner and taillights. Or it could have been the Bulbs in the taillight that burned out the switch.

If you visit the MWFI page they show the C injectors as only up to 92.5
