Leak

[02Steve15]

I had this problem a couple years ago because the rubber tube cracked. It's on the driver's side under the bed, right near the fuel tank. Is this tube going into the fuel filter?

i think that is part of the EVAP emissions crap. Someone can say better. But by the looks its going into the charcoal canister.

Last time I had this issue I threw a CEL and it was a small evap leak like you mentioned. No CEL yet, but I will switch the tube out tomorrow most likely.

Make sure you use hose rated for Oil / Fuel not heater hose.

Yeah I picked up some hose designed for fuel

Also, it was leaking a yellow fluid..

Could have been just old fuel that settled in that line as vapor, they are right its for your EVAP.

Alright so since it's for the evap system, is heater hose going to be alright? The tube I just pulled off the truck was PCV hose and that was what I used to replace this when I had my first leak there.

The heater hose was the only one with a big enough diameter that would fit so I just picked that up...
