P0455,evap system leak (large)
#3
Thx for the quick reply - guess I'll have a little work to do this week inspecting the problem-maybe the fumes is coming from a cracked hose?
- I'll be cking out the link you sent. Have to ask around for a LPHV spray paint gun regulator,
But yes, I have air-& soapy water!
Thanks again fixkick , - Regards 98TrackerMan

and it comes back you have an EVAP breach.
it is a large leak
there are only 2 ways, besides, looking for rusted top of tank or hose cracks
that is pressure testing or vacuum testing it, called a leak down test.
one way is use a LPHV spray paint gun regulator, set to 1 or 2 psi, lowest possible (got shop air?)
then pressure the system.
then listen for leaks using a rubber hose to ear.
and or use soapy water to find bobbles, same way the gas man finds gas leaks on furnace leaks.

that smelt fumes is wrong.
