5-6yrs ago I was at a friends house when a huge thunderstorm hit...major flooding. I got in the truck and did a couple deep water crossings. Later that day I pulled in to refuel and was unable to get more a sec or two of fuel. Pump would shut off like it was full. Pulled the handle out and fuel was indeed full to the fuel door. It would slowly trickle down into the tank.
Got the truck home and pulled the inlet tube, verified the check ball was moving and looked around not seeing anything out of the ordinary. Put it all back together and haven't had an issue till today.
Last friday we had another deluge of water. Had a couple deep water crossings. later that day I could not fill the tank like previously. I had enough fuel to get home and parked it. Today I again try to fill the tank and same symptoms.
Get the truck over to a buddy's who has a full lift. This time I pull the vent line from the fill cap to the tank...rubber at fill cap and turns to metal tube. I verify the rubber portion is clear. Connect a hose to the metal tube going to the tank (topside) and blow/suck...nada. Can't get air moving in either direction.
I get my remote visual camera up on top of the tank and see the hard line goes to a connection on top and there is another hose T onto the same connection. Follow it forward and it goes to the EVAP cannisters/purge valve etc in front of the tank. I pull where this hose connects to the EVAP cannister. I go back to the hard line and blow/suck....still no air movement.
At this point I add a little bit of pressurized air to the tube....about 1 oz of water discharges from the EVAP side of the hose. Blow a bit more air to make sure all water is out. Put it all back together and attempt to fill with fuel...no go.
Did some research tonite and found several similar situations with other dodge models. Went thru some of the do this, test this procedures and at the end situations/solutions I found posted determine that the connection point on top the tank is actually a valve. Fix is to replace the tank. It appears that valve is not sold separately. heck, I don't know if its removable.
Only way to get my hands on the valve is to pull the bed or drop the tank. Decided to leave it alone for now. Anyone run into something similar, know of something similar or any suggestions. The water part has me a bit stumped.
Edit: I did speak with a mechanic buddy. he is not dodge specific but he stated that the EVAP system will go through a purge cycle after an initial start up...usually within 10 min. Both times I was in deep water within that time period. The EVAP cannisters do have vent intake but its located above teh cannisters...I know I wasn't in that deep of water. However, there is what I think is a purge valve with an open nipple that hangs pretty low off of the cannisters. Maybe water entered thru there....:dontknow:
Before I get under the truck and start fumbling around trying to figure out what does what and what goes where and dropping the fuel tank thought I'd post this to the collective... THIA
