Different nozzle sizes

Some diesel pumps have the smaller nozzle that fits fine in our inlet while other service stations only have the larger nozzle. In order to use the larger nozzle I have to hold the nozzle partway out and slow down the fill rate in order to keep fuel from spitting" back during a fill.
Is there a remedy I am missing? Replace the fill neck with the larger size if possible? Or just live with it?

What vehicle are yu having the issue with ?  Surely not the coach, however on my service truck with the service bed, the fuel hose is a long S shape and if you try to pump too fast, it can not handle it at full blast, other pumps are very slow and never have an issue.  So for me I learn to live with it.

Sounds like Nitehawk is talking about my VW tdi at a truck pump.  Can't believe they put a small inlet on you take.  My U225 has no problem with the large fues pump nozzles.  Don't know what to  tell you except I can see problems if you try to make the inlet bigger.  Chance of shavings getting into tank and that kind of stuff.

Norm,

I have similar issues filling from a truck pump with a large nozzle. I prefer to fill from a small nozzle. I figure it's an annoyance that I'll continue to tolerate.

I have difficulty using the large nozzles to fill the U295. The limited clearance above the filler neck makes it difficult to seat the nozzle in the filler neck. Also, it seems that the big nozzle restricts air flowing out of the tank so that the nozzle will shut off or spit if the flow rate is high.

Yup JD,
Same problem. I wondered if it was just certain year coaches, like our '89, certain engine sizes, or just random choice. Would FOT know why?
The first time I encountered the large nozzle I inserted it all the way into the inlet. Back spray was excessive in that I got a bath.
The one thing I do like about the large nozzles is that I can put in 50-75 gallons real quick. What I don't like is that I have to hold the nozzle partway out the entire time I am filling.
This leaves very little free time for watching the dollars roll up on the pump. There were times I thought I saw smoke coming off the dials they were going so fast.

If blowback is a problem when using large nozzles, why not just remove both filler caps when fueling?

I considered doing that, but I prefer not to have an open cap on the other side of the coach while I am putting fuel into "this" side. I've been a bit more attentive to filling since a significant quantity of fuel ran down the side of the tank when the nozzle didn't shut off. The pumps were very slow, the temperature was about 15F, and I was watching the pump from inside the coach. I think the nozzle didn't shut off properly because the fuel was not being pumped at an appropriate pressure.

The nozzles with the lip at the tip cause the most problems. It expect they are good for holding the nozzle in a big truck tank filler, but they barely fit into the fill tube on the FT.

The annoyance is one of the little prices to pay in exchange for the fun of Foretraveling.

On your ored if you look under the coach you will see a long pipe coming from the fill opening that then enters about half way up on the side of the tank, so there is no way to make it fill real fast due to 2 factors the first the diameter and length of the pipe and then the fact that it is having to push up the fuel after reaching the half way point.

Wow I get to remember old fixes.

Drop the air suspension all the way and manually raise the front end to the end of the travel. 

I used to also pull into fueling stations and have the tank fill uphill.  The jacks were the way to get the last twenty gallons in the tank for sure....

I don't remember an air dump on my '89 ORED?  Didn't have it long so maybe I just never noticed it.

Most probably aren't that intimate with the ORED.  There's not a large tank in a bay like we have on the U chassis's, nor is there two fill spots.

In the leveling panel with hwh auto level.  Have to think about flipping the levers.  The first step was to flip the jacks down.  Then the bags were dumped.  Then stop the system by turning it off.  Then back on and manually raise the front two jacks.  Engine off. 

Then lower the fronts.  And restart the engine.  When back to ride height retract the jacks.

Ahh yes, think I remember.  Only used the jacks once.

I sometimes think I am asking for advice on the 1932 Ford Model B sedan when I see some of the answers I get. Air suspension? Air dump valves? Duel fill openings? Levers/switches next to the HWH leveling system? Tilt the coach? Filler neck halfway up the tank?
Nope. Nope. Nope. Nope. Nope. Nope (near the bottom of the tank).
Our coach is the basic no frills model. Kinda one step up from the covered wagon compared to most of the coaches on the road today (and we love it--less things to go wrong or worry about) but thanks for all the ideas.
One thing--would it be feasible to increase the vent line so the higher delivery rate that displaces the air could go out the vent and not back up the delivery inlet?

I don't think that would help all that much, but mean dropping the tank to access the vent

Red T, Thanks.

Guess that is one more thing to try to modify if and when I finally drop the tank to repair/replace the sender unit.
