2005 Yukon Hard to fuel up

2005 Yukon Denali 6.0 1500 series. Ever since I bought it I had to baby the fuel in when gassing it up. Sucked on cold days. Bought a new vent solenoid/canister and installed it a month ago. Significant improvement but I can still only use the slowest setting on gas pump handles. Wondering if there could be a plugged line somewhere or if there is an additional part that could contribute to the problem?
Thanks for any thoughts or suggestions

I think there are TSB's on this.....

If you replaced the vent solenoid, then I would be looking at the hose between the solenoid and the charcoal canister......also, you have to check for power/ground to the solenoid......

Thanks very much for the info. I did check for power and ground and it was OK. I will check out the hose as I need to relocate it anyway. Just waiting for the mud to go away to tackle that part of it.
thanks,
