Before you start modifying the size of the vent hole in you tank, try filling the tank with  the fuel line from the tank removed at the at the filter.  This should double your venting capacity.

If this works then you will know if inadequate venting is really the problem.

I assume that there is a filter on the end of the pickup and you would remove tube and filter  before you tried my idea.

Sorry Jim,  I deleted my comment. After I wrote it, it just sounded bad.

No Problem CS, I should have been more explicit in my idea.

I have owned two Arima's and never had the need to remove the main plastic tank,  I have pulled many metal tanks and they have all has filters and line that were removable, leaving the vent above the fuel level when removed.

I just hate to make mortifications that are not reversible when trouble shooting a problem.

Can anyone confirm if the 27 gallon plastic tanks have a filter or screen on the fuel pickup tubing in the tank?

Had a look at the vent on my 2013 tank today. Took the hose off the vent, vent is 3/8” inside diameter. I can easily blow through the hose and feel the air exiting the vent fitting in the splash well.

Im pretty sure that’s my problem. Mine is only 1/4 inch ID. Your the third member that has measured 3/8 on theirs. By the way, do you have any problems filling up?

No issues filling tank. It doesn’t take it really fast but I can easily fill it in less than 5 minutes.

I was able to hand drill out that vent hole to 3/8 ID. I used a sharp drill bit and a vice grip to turn it. Took a while, but it worked. I put some thick grease on the drill bit and it did a very good job at keeping all the plastic shavings on the bit and out of the tank. Won’t know till I fill up again.

   Glad to see you managed to get that opened.  I'd be willing to bet you'll see quite a difference in venting.  If I get ambitious, I'll pull my vent hose and check the hole size.  I don't seem to remember it being as small as 1/4".  About the pickup screen:  Stupid me.........I never paid any attention to that pickup tube when I had the tank out.  :doh:

Excellent glad you were able to fix it. I agree with Yat that you will see a difference in venting.

My boat has the opposite problem as you .
When my tank is full gas starts shooting out the vent into the splash well before it clicks off .
Oh well I just learn to live with it.

Do you have an open style vent or p-trap type?

I tried filling gas today with the vent hole enlarged to 3/8, not much help. I can only pump gas at maybe 1/4 flow of the pump. Gas spills out the filler and the p-trap vent now. I know we pretty much covered almost everything in this 7 page thread but if you guys can think of anything else I could try I’m all ears. I know the USCG specs say 7/16 minimum vent hole diameter and I’m now at 3/8, or 6/16. I wonder if another 1/16 would really make a difference? Appreciate any other advice. I’m really not liking cleaning up all the gas that spills in my splash well. Hopefully gas will not eat my gel coat. :shrug9:

Sorry I don't understand why that is happening. The only problem I've had is when I push the nozzle too far into the filler neck. I have the same setup as you, as you know.

As John said the nozzle needs to have room areound it for airflow. Also I know you shortened your vent hose to make it more vertical, is it now installed without any low spots to inhibit air flow?  My vent pipe hole is definitely no bigger than 3/8” so I don’t see any larger making a difference.

I know mine has a screen filter on the end of the pick up line that lays on the bottom of the tank. I think they all do.

I had this happen the first time I filled my boat, now I take the take the back panel off and watch the fuel level and stop just before the fuel filler neck.

I’ve tried pulling back the boot on the pump nozzle and holding it up with air space and no help. The vent hose has no low spots. Maybe the thickness of the filler neck on the tank is catching the gas and restricting the flow? But then why would it come out the vent too? I had 10 gallons in the tank and added 5 more gallons so 15 gallons. The tank is far from full.

John, are you able to pump at full flow, or close to it?
