96 850 throwing P0442 code (small leak)

Post by joe_pinehill »

My 96 850 tripped the P0442 code. I have time to trouble shoot this week. I couple weeks ago I tried removing the carbon canister, but it wasn't obvious how to do it. If the single 10mm bolt is removed, does the canister drop from the bracket from beneath the car? Is there enough slack in the hoses to remove the canister and replace J hoses? Are the J hoses still available or do most people replace with common hose from the autoparts store? thanks for any help.

It is a vacuum related code.
There are several locations of this leak, search MVS for notorious P0442.
One discreet place is 4" hose connection to valve, no obvious, just above the fuel filter.
