Another 2 door Tahoe for me

I keep forgetting to update this thread….

This fall I noticed the 1/4” return line from the IP and injectors was cracking. That hose was some diesel-rated hose that I bought from McMaster-Carr that was a good price, but obviously wasn’t great quality.



So I got to drop the tank and replace the hose with some Gates Barricade hose with an SAE 30R14 rating. This stuff should hold up well. This is what I get for trying to save a few bucks.

I thought I had replaced the hoses on the Tahoe at some point in time. Must have confused it with something else again. Seems there was a couple things I thought I'd done to it that must have been one of the Suburbans or trucks

Last winter I did a 100% new fuel system in it..........so you may have changed the hoses, but I ripped everything out that was in there to start fresh.

Wow, that hose only held up for a year?

That is really odd!

Yeah, I was surprised and disappointed for sure.

Maybe you got yours out of a batch that had been sitting on a warehouse shelf since before the pandemic? But still, installed in a location where it wasn't exposed to the weather, extreme heat or sunlight, it sure does look like it was exposed to UV/ozone or something that caused it to harden and crack.

The power steering/hydroboost hoses have started leaking, so I replaced those today. The front has some looseness, too, so I decided to take a look at that…. I found that the rag joint was adding a lot of slop, so I replaced it with the 137,000 mile one out of the red truck - a good improvement over this 319,000 mile one. The steering gear also has some slop, but I wasn’t prepared to deal with that today, so I left it alone for now. It definitely drives better now. Interestingly, it also steers easier now, so either replacing the fluid with newer fluid, or maybe the old hoses had collapsed internally, either way, it’s better now.
