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 :mad:

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

Ya that's the second arnott pump in under 2yrs that's had to be replaced, shocks seem to be holding up ok, going to go with the dorman pump this time, it will be here tomorrow

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.

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.

How did you get the smoke (from party smoker) into the EVAP port on the motor?


Ok, I meant, how did you get the smoke from the machine into the car, I reckon shaping paper into a cone and tape and then into a hose and on from there.

I had a small plastic funnel that worked. I just used electrical tape to hold it all together.

probably just bad luck on my end, I haven't heard anything bad about them which was why I chose it as well as the price and warranty but the dorman has a lifetime warranty as well, I might just keep the replacement arnott they send me as a spare

I just need heavy duty stuff, I tend to break things, when I went to drop the pump to check for leaks one of the mounting bolts was snapped in half, other than that I don't know how I could break the pump I was suspicious of it when I put it in because it would pump and then seemed like it released a lot air thru the valve instead of just a quick little burst.

Maybe bad from the start then...
