Help! 2000 Vette - Evap Purge Solenoid - Plastic connector/tubing

[zappac5]

Heard a puffing sound on my vette, and removed the fuel rail cover to find that the plastic hose/connector (the end with the test port) was disconnected from the solenoid. Looking into the end of the hose, it didn't quite look right to me, but I pushed it on anyway, did not appear to make a very secure (leak free) connection (although I don't hear any audible vacuum puffing anymore). Any reason I can just replace this with a rubber vacuum hose instead of plastic - if so what size is that? Also, is there any secret to removing those hose other than just pulling off, appears there is a white ring that may need to be manipulated to make it easy. Any help would be appreciated......see the attachment for a picture of the hose.

zappa, I have been watching this thread go nowhere. I don't think that we are intentionally avoiding you. I just don't know if we (those that have viewed this thread) can answer the question appropriately...I know I can't. I may PM C4C5specialist and get him to respond.

Hi there,

The grey part must be depressed to release from the ends and then the hose slides off.

If this was not connected or was leaking, you would set a check engine light with some type of evaporative emissions code.

As long as your not getting that, I would think you have installed it correctly and your just fine.

That is just it, I am getting a P0449 error code that points to the vent solenoid, but finding this hose disconnected, and even after re-connecting it does not fit as tightly as the other end. Was wondering if this is the root cause of the error, that is why I was just wanting to disconnect the whole thing and replace with a rubber vacuum hose, hence the question on how to get it off and what size hose to use? Once I do that, if the code does not disappear, I would focus on the vent solenoid which is a bigger pain in the "rear", to work on.

HI there,

Your VENT solenoid is not there, it is at the REAR of the car, mounted to the fuel tank assembly.

P0449 is basically telling you that there is an issue with the VENT side of the system, not the purge.

Has anyone had the fuel tanks out of the vehicle ????

I guess you missed the sarcasm in my last sentence when I said pain in the "rear". Appreciate the response, but my question was whether having a vacuum leak in the "system" since it purging & venting make cause an erroneous error code. Since I had a definite vacuum leak and no other error code, was thinking that that may be the real root of the problem. Since the purge solenoid happened to be where the disconnect was, just was wondering whether good connection there may eliminate the code. Since I am not convinced I still don't have a vacuum leak, I wanted to try simply to replace the hose with rubber hose, to see if the code goes away before jacking the car to get at the vent solenoid. To answer your question, no the gas tank has not been removed since I have had the vehicle (i.e. 2 years). Guess I would be interested in seeing a diagram showing the complete vacuum system if there is such a diagram. I have the electrical diagram but that is only half the picture.
