Bayliner fueling up issue...anyone run into this before?

[americanmcss]

We own a 1990 Bayliner Capri 2050 which we have just basically restored to perfect working order in the last two years. One problem we have not been able to solve is an issue with fueling the boat up. Whenever we take it to the pump after a day on the lake, or in one case we fueled up on the lake, if you try to fuel up at more than half the pressure you can give it with the nozzle, the fuel starts to back up out of the fill spout and makes a mess. Here's what we know for sure: There are no obstructions in the fill spout and there are no obstructions of any kind in the transom vent tube (we removed both hoses and double checked). Supposedly this is kind of a design flaw and that it was a common issue with the older Bayliners. A family friend has a 1988? Capri and theirs has the exact same issue. I have a feeling it has to to do with the fact that with the way the boat sits on the trailer and then with it being on a taller hitch on my pickup

It has a lot to do with the limited amount of drop between the gas deck plate and the fitting on the top of the gas tank. It also has to do with the fiting on the tank being at the back of the tank. It also has to do with the routing of the fuel line. This is not an issue that is specific to Bayliners. Try lowering the tongue and/or simply fill it slower if you know if this is going to occur.

No easy fix, other than filling the tank slower, I've owned car/trucks that will only allow gas to be filled at slower speeds too. Sometimes adjusting how deep the filling neck is shoved in makes a slight difference, if you stuff it all the way in, sometimes it wont allow for max fueling speed. If backed off an inch or two can make a big difference in fueling rates.

I had an 03 Stingray 180 that did the same thing. Could only fill it at about 1/2 throttle or it would back up on me. I just had to listen to it and back off if gurgled too much.

My 2005 195 did the same thing from the day it was new. Just learned to fill it at half speed and to listen for the gurgle so that you didn't get a bath from the gas coming out the vent.

My '75 Sea Ray does the same thing. The filler neck is pretty much a straight shot into the tank and it is vented but I can only fill up at about half speed. Otherwise I get gas blowing up out of the filler and making a mess. Hard on the wax job. LOL. Doesn't matter if it's on the trailer or if we fill up on the water, same condition. At least on mine, I can look straight down the filler tube and see the gas bubbling up to the top of the neck and I can see gas come up in the neck to tell me when it's full. My '99 Stingray was slow to fill also. The one trick I learned on it was to turn the gas nozzle upside down. Don't ask me why, but it would allow it to fill a little faster. I know it allowed the tube on the nozzle to go maybe an inch or so deeper into the filler neck. That may have had something to do with it. Sounds like you just need to take it slow when fueling up.

....maybe check your fuel vent for restrictions like spider webs, mud daubers, etc.

Mine bubbles up, too. I found that if I make sure the gas pump nozzle is aligned with the fill hose (past the cap and toward the gas tank) I have fewer problems. I also don't put in any additives (if I am using one) until right near the end of the fill up. I also only pump about 1/2 - 3/4 of the pump's max.

This seems to be a pretty common situation.
