M-chan, FINALLY, somebody gets it. As I look for more power, if I have the mechanical pump, I am more similar to the early PS, and if I have the electric, the later. If I were to go out and look under the doghouse cover, will I be able to see the rectangle or round turbo exhaust inlet ? Can one tell, by engine serial number, build date, or calibration number which one I have ? Thank you ! DF

left is round with a band clamp
right is square with bolts
Knotty, that seems like it should be pretty obvious. Which one of those is which, and does this difference also run true in the Econoline vans ? My 98 is a motorhome, which was built upon an E450 chassis. Has an econoline van snout at the front of it. DF
I am buying a 98 7.3 power stroke from a coworker rn
[QUOTE=dinosaurfan;20862017]Hey All, why are the 7.3 PowerStrokes split up between 94-97 and 99-03 ? Where do those of us with a 1998 7.3 PS fit in ? YES, NINETY EIGHT! Don't even try telling me there aren't any. I've seen three in just the last year. Are the 98s on some kind of pariah status
Mark, you are a transmission guy, correct ? Can you tell me anything about the E4OD trans the vans cam with ? are my shift points like the pickups ? If I am running full throttle, does that ALWAYS make the trans shift down to third ? Does anyone make a shift kit to downshift less often ? Or, is the factory programming best for a van body running @ about 16 K lbs ? DF
I have a 98 E350 manufacture date 04/98 . I have ordered up pipes 3 times and 3 times they were incorrect. First came with a square y pipe, mine is round. Next 2 came with bellowed up pipes that were too long. Each 'expert' was sure they were correct each time. How the heck do i get the right part?

As already mentioned above, there is no 1998 model year F-SERIES (F-250 to F-550) equipped with the 7.3L Powerstroke. As Mark pointed out, production of the 1999 model year F-SERIES Super Duty lineup of trucks began in 01/98, and hence why there are early build 1999 and late build 1999 model year Super Duty trucks.
Since this thread is about 1998 model year E-Series equipped with the 7.3L Powerstroke, maybe I will add a little bit of information exclusive to 1998 model year E-Series. Early 1998 E-Series equipped with the 7.3L Powerstroke will have a mechanical lift pump along with a rectangular shaped turbo exhaust inlet, similar to the version used in the '94 to '97 F-Series. Later build 1998 E-Series equipped with the aforementioned 7.3L Powerstroke will have the frame mounted electric lift pump along with a circular shaped turbo exhaust inlet, similar to the ones used on the '99 to '03 Super Duty trucks.

In other words, you have a late build '98 model year E-Series. Next time you order parts, ask for a late-build '98 model, or better yet a '99 and you will get the correct parts.
The third set I ordered was 'early 99'. The shop said 04/98 is early 99, cant remember when it switched to 99. Anyway it also came with bellowed up pipes that were way too long. If it didnt have the bellows it would have fit. Those were ordered from Puredieselpower.com

The OBS body style (aka areo-nose) terminated in 1997 with the launch of the 10th generation F-150's. The super duty pick up plants weren't up and running until the 1999 model year, for two years or so Ford sold F-250's (non-Super Duties) that were beefed up F-150s with new badges. F-350's got the year off for 1998. However, the e-series (econoline) vans and chassis were in production without interruption and therefore you can find a limited number of 1998 power strokes. The 99+ super duty powerstrokes had some significant differences than the 94.5-97 PSDs, with the arrival of an electrical lift pump, factory intercooler, different turbo, different HPOP, injectors, etc. The 98 PSDs are a bit of any oddity, especially with a lot of part sources skipping 1998 as a searchable option.
The non-super duty F-250s always threw me...
I guess it was the TitanXD without the cluster of an engine that was that Cummins 5.0....

Can you clarify with me then, i have a 1999 f250 with a 7.3 powerstroke. The sticker on door says 3/98. I want to dig in and find a leak, so was looking at a turbo pedestal on riffraff diesel. I am thinking of deleting the EBPV valve. But according to the fitment on their web page, it says " Fits 1999-2003 7.3L with engine manufacture of 12/8/1998 and after". So, this wont fit my engine, correct? And this leads me to wonder, what is the difference between my engine, and one made after december 8th of 1998? What all would you do while tearing apart to replace the pedestal? Once i figure out which pedestal to use, i am also planning on buying a fuel bowl rebuild kit. Anything else? Ive read about replacing seals on HPOP as well? While im playing mechanic, which im not one,how can i make this truck go over 69mph? Its right under 2000rpms. Gets there fine, just wont go over, speed limiter or something? Thanks
there were "early 99" and "late 99" engines. the early version, which you have is based off the 97 engine. the late 99 is the new design.
some parts interchange, some don't.
an easy way to tell early 99 is they usually came with 5 speed manual trans. late 99 got the 6 speed from what i have seen.
