I'm a little confused here.
Where is the gas coming out from? Is it coming out from the vent or filler cap when your filling up?
Your set up looks exactly like mine, but I have the old gas lid that lifts up and I can put a stick all the way in and down to the bottom of the tank with nothing stopping it.
Maybe try poking a long clean wooden dowel down the filler fuel hose to make sure there's obstruction down there.
Or another option might be removing the fuel filler hose or other hoses to see what's happening.
Once I had a similar issue with gas pouring out when I was filling up.
It was a stupid weird problem, it was the angle of the fuel pumps metal nozzle. If the nozzle was at an angle and the nozzle was not inserted all the way in, the fast flowing gas would spray fuel out of the fuel hose and back out into my splash well. To correct it I pull the safety boot on the pump nozzle all the way back and push that metal nozzle all the way in, while holding it in place while filling up, also not letting the nozzle rest against the fuel hose.
The funny thing is, I only have this issue at Chevron's, go figure :shrug9
 Just my :twocents:

AJ, the gas comes out the filler while pumping. I tried the pump nozzle all the way in, pulled back no help. It was a Chevron station too. Took a  :arms: amount of time just to pump 10 gallons! Kind of embarrassing with all the people at the gas station watching all that gas spill out my splash well drain hole :doh:

Funny I just read that article while the wife was shopping. I dug a little deeper and it seems quite a few Arima owners had the same problem. Do I need to shove a funnel through the fill hose straight through into the tank? :hoboy: :doh: :shrug9:

Can  you blow freely thru the vent line with the filler cap off? Also check the vent to make sure it is free from any obstructions, some of them have a check valve to prevent any fuel from leaking out.

Jim

Have you tried this, blowing in the vent hose?  Maybe take the bottom part of your vent hose off of the tank and blow in the hose and see if air is coming out??

The 90 degree vent part, looks like it has a slot for a screwdriver to be inserted. If so can that be turned to maybe "open up" the vent to allow it to breathe?

I took that whole vent cap off while fueling, no help. I disconnected vent hose from tank end and yes, I can blow through it freely

That vent hole coming off of the tank seems awfully small. Click on the picture to make it straight I don’t know why they always come out sideways

Can you blow into the tank vent ? (With the fill cap off)

CS has a good idea.

That does look awfully small.. I'll have to take a look at mine in the morning.
Hope you can get fixed.

The 48 gallon tank on my 21 can be hard to fill.  I’ve learned to go really slaw filling at first then increase flow and can usually get to full throttle.

I think part of the problem is the filler neck on the tank itself is thick, so when the fuel is running down the hose it gets caught up on the thickness of the tank neck :shrug9:

   I have the exact same rig as you.  I have to fill my tank slowly as well.  That said, if your estimate of being able to pump only 10 gallons in 10 minutes is correct, then it could be that the vent fixture is restricted in some way.  Just so you know, I can probably pump fuel about twice as fast as you.  And yes, pumping "full throttle" will cause fuel to blow back out of my filler as well.  Sometimes I think these vents are either a bit too small or are inherently restrictive for a reason.  Remember, they do have to keep water "out" of the tank, right?    Still.....seems you should be able to fill at least as fast as I can.  :shrug9:

I took some pictures of mine, for your reference, which looks exactly like your set up. I also did a couple measurements of the neck the vent hose goes into.




Here's looking down through my gas filler hose to the filler neck of the tank.

Wow, thanks for that AJ! Ya ours look exactly the same, looks like the vent from the tank is only about 3/8. I’m heading out again today for some afternoon fishing so I’ll see what I can do as far as the pump nozzle goes. May try to hold it in different positions/angles and see if that helps. If not it’s going to be a sloooooowwwww process. :doh: :gone_fishing:

Are you filling your tank at a station that has the vapor recovery system on the pump handle?

Also you problem maybe cause due to  the short distance from the filler and tank.  The end of the pump fill may not be aligned with the tank opening and is sitting on the ledge and causing a restriction.  Might try not sticking the pump nozzle so deep in the filler.

Yes, it’s a Chevron station with vapor recovery. The filler hose does have a bit of a curve to it so it’s not a straight shot into the tank. I also think the gas gets caught on that lip

Try going to a Shell or 76 and see if you get the same issues. I go to 76 and have no issues now, knock on wood. But some Chevron stations can be a PITA when filling up the boat.

Enjoy fishing :gone_fishing:

Newer fuel tanks (2016 and later) are designed to be pressurized to 1 psi to reduce emissions, and the vent lines typically run through a charcoal canister of some kind.  Maybe quiz Arima and see if the vent fitting they used is one of the newer designs that only vents under pressure.

My other though to check and make sure you do not have any kind of low point in the vent line.  If liquid fuel splashes up into that low point and can't exit, it will cause a vapor lock that prevents venting.  With that style vent/P-Trap you really don't want more than a few inches of slack in the vent line when it is attached.

Filler tank vent hole is plenty big, I'd think.  You are venting air, not liquid.  That cover that screws off the vent is for inspecting/cleaning it, or testing it with backpressure from an air tank.  The actual guts of the trap are inside the main plastic housing.

Sounds like those larger tanks have this issue, maybe too much tank area to vent quickly........looks like you will need patience at the pumps.

May not help much but you could chamfer the ID of the filler on your tank, it may cut the splash some when filling :shrug9:
