every time i go to fuel my truck i can only hold the nozzle at about half speed, if i give it anymore it tends to get an air bubble and gas shoots back out. any help on what it is and how to fix it? and is it an easy fix? also had another question. im in a diffrent weather climate then what my truck was used for, constant cold weather. Is it normal to hear a slight knocking noise when i first start and run my truck until it warms up? after that i dont hear it.

 

the fuel sounds like a bad vent somewhere which you'd have to find which one it is first. For the knocking its probably just the cold oil not being able to flow through small passages till it warms up and thins out a bit. Mine has a slight cold knock from time to time but doesn't seem to be causing any issues.

 

I had this happen once on a Hyundai Enatra, it was the "fuel recover venting" as Pearlkid said.
If you were living in a warm climate, like Florida, you might have had 10w30 weight oil. You may now be in much colder climate, like Maine, and your truck will call for 5w20 now. The First number is the weight/viscosity of the oil when cold and the second number for when it's hot. Your change of climate dictates what range the oil should be in. Your owners manual should have this info in it.

Hope this helps.

well i was living in kentucky which extremely humid all year round, i live in quebec canada atm and the average temperature durring the winter months like now can be below 0, so what would you suggest for that extreme of temp? and is there anything i would need to change in the truck ( I.E. parts) since im changing the oil that normally wouldn't be used in it?

 

If its an 01 like your signature says its most likely 5w20 regardless of temp you can change the viscosity without changing anything else but id check the owners manual first to see if it suggests other viscosities based on temp.

 

The fueling issue could be related to a bad canister vent solenoid or a plugged charcoal canister. When fueling up the fuel vapour in your tank gets pushed out by the incoming fuel into the charcoal canister to be stored until the truck does a purge. if the canister or the vent solenoid (normally open) is plugged then the only way for the vapour to escape is out the filler neck which causes your slow fill and blow back.
