Coolant overflow tank hose leaking??

I pressure tested my cooling system yesterday, and found out the upper radiator hose has a leak so I replaced it. topped off radiator and burped the system. After cool down I checked the pressure again, pumped it to 18 lbs and slowly dropped to 16 lbs in 2 mins and held there.. Is this fine??

When I got home last night I found white smoke coming from the radiator.. so this morning I checked the coolant level, it is not low, so I thought it was the coolant on the fan or the hoses burned off which made the white smoke. I then started the jeep, 1 or 2 mins later I found that the overflow tank hose was leaking at where it connects to the radiator cap neck.... I cant seem to find the hose on the online parts store, most of them sell the tank with the hose as an assembly. does anybody have an idea where I can buy just a hose? any part number? do autozone or advance autoparts carry it? I just dont want to wait and want to have this fixed asap..

thanks!

Sounds like you could use a new cap also...

Due to the fact that you stated you lost about 2 psi in 2 minutes...mine had a gurgling issue for a while, no real overheating issues, but a new cap fixed that. If it's not holding pressure, it will allow the system to blow off steam prematurely.

And it's something cheap to rule out...
