2003 Sebring with small evap leak
 

I don't remember the exact code number, but we are getting a code for a small evap leak. Changed the gas cap and cleared the code, but it came back. According to people who know more than we do, the issue is usually with the lines coming off of the evap solenoid canister. My husband is able to DIY most things so we started looking for the parts. The canister is easy enough to find and pretty cheap. However, the vacuum harness is no longer produced and is not available anywhere. I know that Dodge/Chrysler basically always had several versions of the same car running around, and that changes from year to year tended to be minor. Has anyone been able to find a vacuum harness from another year or model that will fit? I am left wondering how dealerships fix these when they come in for service. They must be able to find useable parts somewhere, and there are still people like my MIL who take it to the dealer for every little thing.

I know this isn't a major issue but we'd like to fix it because the car is my daughter's daily driver and the check engine light is stressing her out.

I've been around(working on and driving) OLDER vehicles for some time now, the plastic portion of most EVAP tubes do not generally go bad. The RUBBER hose connectors of them do, and lengths of the various ID size replacement rubber hose(cut to length by you) can be found easily at any auto parts store to replace any cracked ends that can cause these EVAP codes(yes there are a few different codes for leaks).
My suggestion is to have a good independent repair shop perform a smoke test of the vehicle to pinpoint where the leak(or leaks) is, to bring about a known and proper fix to the EVAP system. WHOLE LINE replacement is not a very cost effective way to tackle such a problem.
Whatever you do ...GOOD LUCK, and keep that near antique rolling!

have to do a visual on ALL the hoses from engine compartment to fuel tank, if none is found you may need to have the evap system smoked to find the leak
