Marshfly Posted October 11, 2016 Report Share Posted October 11, 2016 With only about 75 hours on the boat, it's to the point where I can no longer fill ever without very slowly filling and having the pump click off constantly. Has anyone removed/bypassed the charcoal canister to fix this? Is that the real issue? The issue was occasional from when I bought the boat but now is happening every time.

conocean Posted October 11, 2016 Report Share Posted October 11, 2016 I've always had to slowly fill my tank while my trailer is hooked up to my truck. However, I can fill it up very quickly if I disconnect the trailer and make it level OR fill up the boat while its in the water. Link to comment Share on other sites More sharing options...
Marshfly Posted October 11, 2016 Author Report Share Posted October 11, 2016 So it's a fundamental design flaw. The ability to fill the fuel tank at a normal pace on the trailer should be built into the design, don't you think? Do you have the charcoal canister in your boat?

conocean Posted October 12, 2016 Report Share Posted October 12, 2016 The only way to really top off the tank is by filling it while level so I don't think it's a design flaw. I've never seen a charcoal canister in my boat. Link to comment Share on other sites More sharing options...
JnamJnam Posted October 12, 2016 Report Share Posted October 12, 2016 Never once had this issue. I always fill up on the trailer and hitched up. Maybe my truck sits perfectly level with my boat. Link to comment Share on other sites More sharing options...
Marshfly Posted October 12, 2016 Author Report Share Posted October 12, 2016 Mine is pretty darn level too and I am having the problem constantly. With the location of the tank, it would have been simple to have the fill directly over the tank with a straight shot in. My last skiff was this way and I could have filled it with a fire hose. I'm yanking the canister to see if that helps the problem. Taking 30 minutes to either unhook and retook my trailer at the gas station or baby the gas in an 1/8 cup at a time is ridiculous.

The charcoal canisters, check calves, and non-venting tanks are a fairly new regulations, not sure when it went into effect. Brought to you by the same people that managed to ruin gas cans Somebody on here is pretty smart on the entire newer tank setup, don't remember who but maybe they'll chime in. I don't know if simply removing the canister is going to alleviate all your problems. There's much more to it if I remember correctly. Link to comment Share on other sites More sharing options...
Marshfly Posted October 12, 2016 Author Report Share Posted October 12, 2016 From what I've read, you want the fill going as downhill as possible without any upslopes and the vent just the opposite. Get that right without the canister and it should flow well. I'm going to work on this and report back. I'll try to get pics but due to the location of this mess on top of the tank, it might be tough. Link to comment Share on other sites More sharing options...
Marshfly Posted October 12, 2016 Author Report Share Posted October 12, 2016 I got a chance to take a really good look at the hose mess under the front deck this afternoon. In addition to the vent that flows through the canister on it's way to the through hull there is also a separate hose that attaches to a vent in the fuel fill under the cap. So there should be plenty of venting. What I did find that concerned me was that the actual fill hose has to run uphill due to the long run across the boat from the fill to the tank inlet and the inlet sitting so high on the tank. The real fix is to have an inlet adjacent to the fill on the end of the tank to give the hose a short straight shot into the tank. The reason the fill is intermittent is probably due to the slope of the concrete downhill and away from the pump on the outside pumps of most stations. if you are on the inside pumps where the pavement is flat, you'll have problems because the hose has an uphill portion. On the other hand, if the fill side of the boat is a half inch higher than the other side it will all be downhill and should be fine. Regardless, I cut a half inch out of the fill hose to tighten up that sag that is there and give it a better shot. I'll try it this weekend and we have a 2 day tournament next weekend so between scouting and the tournament, I should get a few fills in then.

2shallow Posted October 13, 2016 Report Share Posted October 13, 2016 I placed a small block of starboard under the lowest point in the fill line to eliminate the sag. As a result, I have no issues filling my tank. Link to comment Share on other sites More sharing options...
Marshfly Posted October 13, 2016 Author Report Share Posted October 13, 2016 As I was driving home that exact thought came to my mind. Glad to know I was on the right track. Will probably just zip tie it to the hose so it doesn't move. Link to comment Share on other sites More sharing options...
2shallow Posted October 15, 2016 Report Share Posted October 15, 2016 That is exactly what I did. Been that way for five years. Link to comment Share on other sites More sharing options...
Marshfly Posted October 28, 2016 Author Report Share Posted October 28, 2016 Three fills later and a 3/4" block under the hose at the end of the tank makes it work great. Thise of you you that have been living with this, don't. Link to comment Share on other sites More sharing options...
DaveC Posted November 17, 2016 Report Share Posted November 17, 2016 Guy's this is an issue and will be so we have to get used to it, but... With the current CFR standards there is not much that can be done by the OEM, the tank manufacturer can also do very little to make changes in the system that will still allow the installation to pass the EPA standards. These tanks and the boats have to adhere to mandated tip studies having a "static" position predicated by the OEM, if the boat (when you're filling) isn't in that same "float" position the vents in the tank will prematurely close (these are simple floats), so if you're at level or bow down the tank won't fill. Easily anyway! It's complicated by design I think... Also, it's against ABYC to have the fuel fill inside the gunnel (I know some boats have center tanks but those are typically rolled edge products without electric in a bilge area, or a bilge?) Sorry to be even more confusing... Link to comment Share on other sites More sharing options...
