What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[07Burb]

Hooked up the tech2 and inflated the shocks to 18psi I will let it sit a while and see if it changes, I sprayed soap/water all over don't see any bubbles so far

***edit only been 10 minutes lost 4psi already but can't find the leak

Pst pst....it’s leaking where you hear the or making a hissing sound

It might be the pump, I have a spare T connector and so I looped it back to it's self and it still looses air but even faster and nothing on the T connector is blowing bubbles, I sprayed the whole pump and no bubbles there either i don't know where the exhaust port is on this thing

Must be the pump I guess the intake filter is also the relief port or it's just bad

I replaced mine with the Dorman pump and so far no issues.

Also, sorry I haven't checked my shocks for you yet... it's been a busy week for me, with no signs of any relief until next week sometime... lol

no problem I figured there must be a leak because I remember them holding air before but wasn't 100% sure if it was normal or not, me and my friend stood on the bumper this afternoon adding about 500lbs and it kicked on and pumped the shocks up nice and firm but then after we got off it released the air a bit and by the time I got home I could squeeze them by hand pretty easy. I also noticed it seeming to be kind of sloppy when driving sometimes.

Yeah, and now y'all gotta wear sunglasses inside at night when you open the doors or need to find something! LOL

Yeah my wife wasn't a fan of the LEDS in the vanity mirror...(I still haven't changed them back)

Installed the Vapor Canister Vent Valve hopefully the fix for my P0455, I think so since the old (I think OEM, but likely not) piping that went from valve to canister was rubber and pretty cracked(likely leaking), the new style uses a rigid pipe.
Went a lot easier than I thought it would.

Also ran a can of Seafoam in the tank today, and SeaFoamed the upper...

Still dragging my feet on the driver side motor mount...lacking commitment at this point.

I’ve had my Arnott pump for 4 years so far. No issues.
