Why do you have to do inj?
What are your HP goals, and what do you do with your truck...tow, play, DD, work?

My fuel dilution went from 1.5% to 5%. Mostly all work/DD and some play. I would like some increase but nothing to big.

180's are good, I agree.
Fuel dilution doesn't mean your injectors are bad. Did you change your driving habits during that oil change cycle...alot of idling time, stop and go traffic...Could just be bad o-rings or bad copper. But if you want to use that as an excuse to do inj., then by all means go ahead. LOL

20mm of fuel is noticeable.. they were rated @ 200 in 99 and 235 or 245 in 00` right? Dont quote me because its been a long time since I drove a 7.3.

Thanks for the compliment Josh. . .your check is in the mail for that pitch LOL .

Actually, the intensifier pistion on the AD's is 29.1mm long while the intensifier piston on the AB's is 29.7 long. Since the plungers and intensifier pistons on both sets of injectors is the same diameter (6mm plunger od and 16mm intensifier piston od), the length of the intensifier piston is the driving force to determine the maximum displacement of the injector. With mild tuning they may perform the same, but when you empty the injectors, the AB's will always fall short of the AD's. Too bad the P&B's are different and it's not that easy to upgrad AB's to AD's. . .guess someone can thank Navistar for that one!

Power rating didn't change between inj changes. They bumped up the power rating in the 03's with programming changes

My 01 was factory rated at 250hp. The difference is noticeable with good programing between AB and AD codes, but it doesn't matter cause you wouldn't want to go back with split-shots if you are going to put in new injectors.

I wouldn't bother with Remans. You can get stock new AC's code injectors for around 185-200 a piece fairly easily so it's really not worth buying remans. For a bit more money you could get some 180cc injectors or do small hybrids.

When I get new injectors, do I need one injector to be longer?

I did change my driving habbit it is all highway miles and only 100, the oil level kept going up. The truck has 252,000 on it so it is prolly time, and it is a good excuse.

Are you sure there isnt a O ring leaking? And yes, you can use a long lead injector for number 8. They say it takes the flutter out of the exhaust.And the engine cackle. It injects more fuel on the inital split. They say this is caused by the number 8 injector following the number 6 in the firing order which are right next to one another on the same bank and the number 8 can a have a underfueling condition from its neighbor just firing. I have heard that the long lead injector can cause a false weak cylinder on a contribution test? But either way.. they will both work..
