can't add fuel without nozzle clicking off constantly
 

I used these forums several months ago when I owned a '98 Jimmy...now I have an 01 Bravada, and I'm hoping I can still post about it here since it is pretty much the same platform.

When I got the vehicle originally, adding fuel was a nightmare. I couldn't do more than 10-15 cents at a time without it clicking off. After doing some searching, I decided to replace the purge canister vent solenoid...upon inspection of the hoses underneath (they all look like they are in excellent shape) I discovered that one going to the fuel tank was disconnected. Reconnected, go to fill up...condition is much better, I can go almost 1-2 dollars before it tries to click off. Would still look to remedy it completely. What else should I start looking for? For what it's worth, I did check all the lines and did not see any breaks/cracks/points of leakage.

Let my clarify, you did replace the vent and purge or you didn't? Every time i have seen this problem its due to those, so if you were saying it looked alright and didn't replace them, i still would

crazy question
have you tried pulling the nozzle about half way back towards you ?

What about that anti siphon ball in there, I'm thanking it could be stuck... Just my .02..

Yup, anti siphon ball is stuck. Remove the upper fill neck and free it up or remove it. The ball is plastic, about the size of a ping pong ball.

Didnt think of that one.. I didnt even know it was possible to get them stuck from the way they sit in there lol. Nothing surprises me tho
