Fuel overflow on an Eagle

basil · March 23, 2011, 03:26:44 PM

If my Eagle is hot and I fill the tank it always overflows after 5 to 10 minutes and keeps overflowing for 30 minutes or more.

I know my 2 stroke recirculates fuel for cooling and remaining fuel and tank and structure are all radiating engine heat, so expansion and overflow make sense.

My question is, does anyone have a method for making the station pump automatically cut off earlier, or a trick for capturing overflow?

Does anyone else have this problem? It can be pretty embarrassing.

If you make sure you place the nozzle all the way in the tank it will shut off at a slightly lower level.

Basil, look inside the frame where the tank is on your 15 it is supposed to have a vent and return line going to the hole in the bottom inside the fuel door have you lost your whistle ? if so the line is broke and open both filler caps when fueling

good luck

Luvrbus, does a 1984 Model 10 have a whistle? I have never beard nor seen one on mine.

Basil,

I'm not sure I understand your problem but will offer some advice. If it doesn't fix your problem, maybe it will help someone else.

Under the fuel fill on both sides there is a hose that connects the filler to the tank. I don't remember the exact size but they are about 3". These deteriorate over time and bunch up inside. That causes back splash when refueling and usually it takes a long time to fill because you have to hold the nozzle and slowly pump fuel in. Using the truck pumps is really a bugger.

Replace the rubber hose with a good quality hose rated for fuel and all those problems go away!

I had the same issue with my 68 , I would over flow when I was almost full, I checked it out and found bad hoses and wrnt to NAPA and got good fuel hose and end of proplem

It was easy to do i just unbolted my necks and cleaned them up and fit the new hose and bingo. Took about an hour all said and done

Basil has a late model 15 it has 4 inch fill tubes and the vent is 1-1/4 inch that goes to both sides from the top of the tank if he looks at the top with the fuel door open in the compartment he will see the vents inside the door and he has very little hose those fill tubes are metal with 2 small couplings about 3 inches long each his vents have to be plugged and those are mostly hose and he only has 1 tank

good luck

What Clifford said is my experience also. On my Eagle 15, i've only slightly overfilled once. Fortunately, i met a guy driving an entertainer model about 3 days after i bought me Eagle and he warned me. So when i get close to what i think i need to fill the tank, i slow down to listen, look and let it breathe. Then i pump another 10 gal in unless i see the foam coming up. Some pumps will stop in time, but i never let the pump run fast without being there and knowing that i've got 30 gal or more to go. if i'm at 1/4 tank, i figure about 120 gal to full, so i slow down at 100, fill the last 20 with my finger on the pump trigger, slowly.

You make some good points, when I fuel it is about the same drill. I gave up a long time ago "on spoon feeding" them, once they click off, I am done. I have seen people stand there and freeze too death, trying to get one cup full of fuel in a tank that is already full by most respects, even to the point of "elevating the hose" to get the very last drop ... almost like Folger's Coffee or something (good to the last drop, remember that one?).
