Did the whole thing again today. Decided to test the new vent valve solenoid I got from Autozone as well as the old one I removed. Applied voltage. The old one clicked. The new one did nothing. I was able to blow through the old one but not the new one until I applied 90 PSI of air. So the...
What's considered the service port?
Also, is there more than one hose up on the intake?
Which line is the 5/8 vent valve?
If it’s the FLVV/internal 5/8 line how do I fix that?
It also gives me a code P0455 and tells me to tighten the gas cap.
That’s the exact process I’ve done twice now. Is there more than one hose up on the intake? Which one is the 5/8 vent valve? If it’s the FLVV/internal 5/8 line how do I fix that? It also gives me a code P0455 and tells me to tighten the gas cap.
Yes that’s the white cap I was talking about. Do they go bad are they serviceable? Lines on the intake? Is there more than one? The only one I blew out is the one that goes to the purge valve and the one that still produces pellets when hooked up and removed. If left unhooked no pellets.
Combination of oem and oreilly parts. The vent valve on the charcoal canister is from oreillys. The canister I believe is from eBay and is Delco. The fuel tank pressure valve is Delco and the purge valve on the intake is Delco.
post 5 doesn't really resemble the setup. the one below slightly resembles it. the circular valve toward the front of the tank near #5 looks like what i saw, but that's not where it was located on my tank.
I blew out every line I could take apart and I understand why I'm getting fuel throwup, just can't figure out how to stop it. Is there a way to bypass it and do a workaround?
Fuel module/FLVV? What do those parts look like and where are they located? There was an off-white valve that looks...
2005 Yukon Denali recently went to fill up put the hose in as usual tried to fill up and in a short time it cut off and fuel spilled all over the ground. Tried this several times and a different pumps same result.
I can put fuel in but have to do it very slowly. It would likely take 30 mins...
