I am having troubles with my new truck, new to me anyways. 2003 Chevy 1500 4.8L 4x4. The check enginge light came on so I aksed a friend to hook it up to his computer and it was diagnosed as the evap vent solenoid. He said it wasnt to big of a deal and reset the code. It stayed off for about two weeks and now it is back on. The question I have is I looked for the part online and it seems rather expensive, well over 100 dollars. Is there any other aftermarket parts that would fit this truck. I cannot afford to spend that kind of money on it right now. Also how do you get the clips the hose off that piece. It has some type of clip on it. Newbie asking for a little help.. Thanks in advance!

Also check the wire going to evap vent solenoid. Mine broke right before the solenoid.

I found the solenoid, two question how do you get the hoses off without wrecking the clips that hold the hose. Second is there an easy way to access this piece, its seems to be a really tight squeeze in there.

I took the part off and cleaned it out about a month ago or so. Had the code reset and it came back on today. Can somebody tell me the cheapest replacement part I can get and the part number. Mine was a little thin rectangle box. Thanks!!!!

has anybody tried the following parts on a 2003, It says 2004 and newer


Ok everyone, listen up....If you have a 04 and newer silverado, with a failed evap vent solenoid, you have to read this info. Do not pay $100+ for this part(actually $150.00 at the dealer). The following part numbers associated with this part have been gm#19207763,19152349, and AC DELCO #'s 214-2082 costing over $100.00 for the modified part. This is for the modified part, with the relocation of the filterbox, and the added hose that seperates the two. No one at Gm will tell you this, but this same part, that was origionally on your silverado, is also used in the 2006 Suburban. It will be an identical replacement for what is ON YOUR TRUCK, and the cost is $24.04 AT THE DEALER. I know this because I own a 2006 silverado, and a 2006 suburban. Looked at the suburban when the part went bad on the silverado(from overfilling the tank)and bingo, same part. Ask a parts person at GM, and they will tell you otherwise, but they are lying to you. Bought the suburban part today part # 25932571 (GM #) and everything is identical, right down to the numbers stamped on the part itself. Took the part off my silverado, put the replacement on (which gm told me is not the right part), cleared the codes, and bingo no more light after 3 consecutive starts...... Why, is it that GM feels we need to pay the price for something they did wrong???? And moreso, lie to us, telling us the $150.00 part is our only choice to fix the problem. My truck went 40K miles with the origional part, and probably only went bad because of my own stupidity in overfilling the tank, whay would I not just want to spend $24.00 to put on the same part, that will probably go the rest of the life of the truck with no tank overfills???? I say CLASS ACTION LAWSUIT FOR EVERYONE THAT HAS BEEN SCAMMED INTO PAYING THE RIDICULOUS PRICE that GM is trying to suck out of us.....Please pass this on to the world, and every forum you can...Get the word out....Let the parts people at GM know we are on to their BS, and they can't take advantage of us like they have.....
