I have noticed the last few days that there was a little oil on the driveway. I parked it last night and checked on it this morning. I went out and low and behold, a metal fitting completely rusted off of my stainless steel braided hose that goes to my FS2500 bypass oil filter. There was no sleeve or nut. My engine was bleeding out oil. I tried to do a quick fix, but had no luck. I took the hose off and went and got a new hose made up at Genalco and I am back in business. The hose is a little overkill, 6500 PSI and very thick rubber with beefy hose ends, definitely better than the stainless steel braided that I had on there that came with the FS2500 kit.

I will be changing the inlet hose before it goes on my own time. ;) It didn't look very good either.

I contacted Filtration Solutions tech support and they were very receptive to what I had to say regarding upgrading the hose ends to something of a better quality to avoid any issues like blown motors, etc. He stated that they had a few issues just like mine from a few customers in the colder climates. He is looking into making some changes to the hose ends. The manufacturer of the hoses stated they had a 15 year life. :lmao: I only got 5 years out of mine. Go figure. Must be due to the road chemicals and salt in the winter months.

The bad news is I had to miss a day of work. :(

That's crazy! Was that an AN-style fitting? I'd assume that as they're aluminum, they *shouldn't* rust...
 
I am not sure on that. I was told it was steel, but it was paper thin. The braided hose was perfectly fine, but the hose end is gone.
 
Damn that's nasty Jeff! :eek: Do you have a splash guard in front of it? BTW, SS fittings are prone to fatigue and snap from vibration. Plated steel is probably best.
 
Good thing you caught it in the driveway, that could have been much worse.

Also a good thing you knew to go to a hydraulic hose house to get another one made. Ed, that's just a typical 37* female swivel used pretty much everywhere in industrial hydraulics.
 
I am going to change the other one ASAP. I will take a photo of the new hose and the ends. Funny how the manufacturer states that they have a 15 year life, and I and apparently a few others didn't even get 5 out of it. I paid extra for the SS lines, but I think I would have been better if I just got the regular hose and had SS hose clamps on it. I'd only be changing the SS clamp instead of a completely new hose. I am kind of pissed at that. It could have been catastrophic, but I am kind of glad that it happened in my driveway so I could fix it. I just came back from NH last week on a camping trip. I'd hate to think what could have happened if it happened on the highway.
 
I changed the other inlet hose today and snapped a few photos. I feel a lot better now that there are new hoses on there. The actual SS braided hose is in great shape, it was just the hose ends that corroded away. I should be good for another few years I guess. :D

New hose end. Bad, corroded Inlet end

Hose end next to OEM oil filter. This is tucked away under the truck in the side of the motor and is not to bad. Shows what the hose end looked like prior to the corrosion.

I'll tell you what makes a huge difference is going through the Superwash with undercarriage flush once a week and it must be a real advantage parking in a heated shop (above freezing) every night because I've driven through 7 salted road winters with that routine and the truck still looks great compared to most every other with that level of use.
<<<There is the proof. I took that picture 2 days ago. 227k+
 
Mike, might I be right in assuming that 90% of the time, 90% of your route is clear of snow by the time you hit it? And you guys don't get the extent of stuff we get... Not saying you don't get hit bad, but being a couple hundred miles south has its benefits, lol. Stuff also doesn't last nearly as long....
 
Ed, I run 35 miles of rural roads to get to I80 and then 22 miles. So in snowy conditions I see mostly snowcover and then heavy salt. Probably about what you would see with a similar distance but not quite as often and for about 1 month shorter season. I've rusted out plenty of trucks and cars over the years until I started this routine with the last 4 GMT800s. 2000, '03, '05, & this '06 but this is the only long miler of the 4. 228k this morning. Couldn't be more satisfied with it.
 
Gotcha. Our D-max is getting some surface rust on the frame, but none visible on the body. I'm afraid to pull off the fender flares to see behind them though...
