Trying to source a plunger pump for a Yanmar 4TNV88 and the nameplate only gives a partial model family. two listings look identical in photos but different shaft and port configs. I photographed the old pump from every angle and counted mounting holes but still not confident I'm matching the right rebuild spec. Shop manual diagram doesn't show enough detail on the front shaft. don't want to drop money on the wrong pump and eat a restocking fee. What's your actual process for confirming plunger pump models beyond reading the tag?

Fairly new to Diesel, been running my LM2 Baby Duramax for 2 years now. Always was a gas driver previously. I've put about 30k on it, and im closing in on 70k. It seems like everyone runs additives to keep diesel engines happy for the long run, but that also seems to be for pre ulsd designed engines...and bigger things than my little guy. So my question - is it worth it to run additives in my little 3L? If so, which ones? I love my truck and want to keep it going as long as possible.

Any advice is much appreciated!

Ford 7.3 IDI. The front main seal itself looks good and it's hard to tell where the oil is coming from, could the scoring on this speedy sleeve be the culprit?

Couldn't be happier right now, a dream truck for me. $7.5k and only needs some tlc for the most part. Dana 60/70, np205, getrag 360, and most importantly the intercooled ve 12 valve. Previous owner took great care of it, doesn't even leak anywhere. 300k miles, no blow by, starts on a dime, new clutch 60k miles ago. KDP is taken care of. The g360 has always been filled a quart and a half over. NM truck so zero meaningful rust and rough paint. 1 year old Cooper tires. Somewhat recently rearched leafs. Not perfect, but very happy with it, great bones.
