Nothing so fancy on my boat. The yard owner speculated that the screens sometimes get plugged with wax from overenthusiastic Karate Kids...

Re: problem with fuel fill

I checked the cockpit end of the vent, it's clear. I decided to follow Bill M's example and disconnect the vent hose at the fuel tank end and use the dinghy foot pump to blow it out. Not surprisingly, it was a lot easier to say it than to do it. I backed both clamps off but I cannot get the vent hose off of the hose barb. Any recommendations for how I could loosen up the end of the hose so I can pull it off? Heat gun or hair dryer maybe?

Re: problem with fuel fill

Small pick
Work it around to break seal
Maybe you can then twist/pull off

You prob need to root the hose out

Re: problem with fuel fill

Heat is always my first thought for stuck hoses, but I’m not so sure around fuel. Diesel will auto ignite around 400 degrees F and a heat gun must get at least that hot. I think I’d avoid.

There is a tool for removing hoses. Looks like a square angled hook. They work great to remove. They often damage the hose.

Here’s a random example.

Re: problem with fuel fill

KB,

How much slack is there in that hose? Seems to me there was plenty. So, if you can't easily get the sucker off, you can just cut the hose off square, then cut the detritus off the inlet fitting, then just slide the fresh end on after you've tested. It's what I did when I replaced our tank.

If you don't have enough slack to cut it off, you can take a large pair of vice-grips and grip the hose at the tank and try to rotate it to break the seal (maybe somebody used a sealant). Don't tighten the vice-grips so much that you might damage the fitting, but just enough to get the teeth of the vice-grip into the rubber. If you damage the rubber, you will only need to cut off as much as the width of the vice-grip jaws. This method has also worked for me in the past. It gives you a lot more leverage than with just your hands.

Dave

There's not much slack but is probably zip-tied to other stuff so if I can cut it loose maybe that would help. I'll give the vice-grips method a try, thanks!

Re: problem with fuel fill

Mud daubers are bad for making nests in vent and discharge lines. They nearly sank a power boat I was on, blocking the bilge discharge. Found the plug just in time.
