Fuel fill and vent spitting on 4388 and other models too-gctid818049

[Captain_Jack]

Has anyone ever replaced the stock fuel vent hose with a larger hose? I've had and heard of chronic fuel fill problems on various models and am currently experiencing a really hard to manage fuel fill on my 4388. I've had her for a month and have fueled up 4 times.

you can hear the air coming out of the vent. The noise at the fill hose changes when you get close to full but it's always a xpyt show when she is full or even close to full.

I'm thinking about fabricating a 1" hose fitting with a flange to attach to a new hole in the fuel tank and adding it to the existing vent system. I'm fairly confident that I will be able to use a 1" hole saw drilling slowly to not generate much heat to make the hole necessary for this installation without blowing myself up.

Has anyone done this or heard of it being done successfully?

I had the same problem with fuel blasting out the filler opening because air wasn't venting out fast enough. I took off the vent fitting and drilled out the screen that had become some what corroded. The air now flows freely and I can pump fuel full flow and not have it back flow at all!! The screen is called a spark arrester. I can't imagine a spark getting anywhere near that area, but maybe I'm taking a chance without it. A new vent with a clean screen might work just as well.

You want a screen to keep spiders out.

Don't feel like the lone ranger. I think anyone who has owned a boat has had this happen a few times. I would be happy if I could admit it only happened to me 4 times but that would be fake news. : )

I try to figure out about how much fuel I need according to the gas gauges and then watch the pump. I can also hear when the fuel is climbing the fill line and then put the nozzle at its lowest setting for the remainder of the fill.

Plus I have my spray bottle of Dawn to clear the gas slick on the water.

I have seen a few longer gas pump nozzles at various marinas that protrude deeper into fill line then the regular sized nozzles which trip the nozzle long before a mess occurs.

Go on youtube and type in how does a gas pump nozzle work and you'll understand.

If you are browsing some old marine stores you may find a Davis No-Spill.

They are discontinued, why I don't know, so you will not find them online but I have used this for 10 years with never a vent spill.

My fuel guy loves it when he is filling my tanks.

Yes, those are great! Many of the fuel docks here have them.

I installed these 8 or 10 years ago and haven't spilled a drop since.

For about you can install a fuel air separator in the vent line and never spill again. I did it and wish I had done it before. No more climbing down the side of the deck to install those suction cup receivers to the side of the boat. I also noted I get a full tank of fuel with no worrires. Everyone should have these. http://www.westernmarine.com/acro. I shopped around and got mine for less than $50 each. NOS

Your link is no good???

Put these on both the fuel tanks and the water tanks. I had volcanos out of both before the change. https://www.amazon.com/Attwood-Flush.../dp/B003EWWJBY Never could fuel even at half speed. Now I fuel at full speed.
