The last time we filled our tank, the nozzle did not kick off, allowing the tank to overflow. Has anyone else had this happen, or have any ideas before we take it into the shop? ('97 LandYacht)

I did have that happen on a much older Airstream Motorhome (1979) .
Once I pulled the Tank, I found unused ports on the top of the tank that were improperly sealed off. It's a very unsafe and dangerous situation und should be looked at immediately.

I had it happen to me once on a passenger car, but never since. It was a defective nozzle on the gas pump.

Before making a trip to the shop for something that might not even be a problem on your end, wait one more fill-up. If it happens again at a different pump, then you know the problem is with your Land Yacht.

The problem is with the filling nozzle, not the vehicle.

Ditto, did you let the station manager know?

Well, we have an appointment at the truck shop to check things out. The overflow came from the tank, not out where the fill nozzle goes, so it appears it is our problem, not the gas station where we usually buy our fuel with no problems.
I will give a report of what is found, hopefully something easy and quick.....

I would say the vent hose is off where it connects to the filler neck.

wheelygoode · 06-17-2015, 05:50 AM

Well, J.Morgan, that was close! It seems where the filler hose meets the tank there should be a clamp, but it was gone. Just what we wanted, quick and easy! Of course there are the other 'while you are here' things, but nothing major, at least for today!
Thank you everyone for your help.

Might be that someone changed the fuel pump and didn't put the clamp back after dropping the tank.

Someone made a mistake or just got lazy.

Glad you got it sorted out!

I had the same happen to me with my diesel. Luckily for me I allways keep a hand on the pump and heard the dripping. A friend also with a classic diesel has had the fuel expand to a point that it drips out of tank.

I have a sticker that states only fill to 95% as diesel/gas can expand quite a bit if the ground tank temp is very different from above ground air temp.

I don't know where exactly what part of the tank it came out of but it must be a safety check valve of some sort that will allow fuel to exit if under pressure from expansion.

Cheers

How do you measure 95% full when pumping fuel?

My Interstate and Honda owner's manuals both say never top off the tank. When the pump handle shuts itself off, you're done.

What Protag said...and all OBDII vehicles have a rather large area at the top of the tank which traps air as the tank gets full. This is an expansion chamber. Many of them are as large as 2 gallons in volume. Don't top off, especially if the vehicle is tilted AWAY from the fill side (ie. that side is higher). That reduces the trapped air chamber by quite a bit, if you top off.
