When I input the gas into my tank, it will spit back up similar to if it was completely full. These is a recent problem and only occurred after we had some work done. If you put it in slow enough, it will accept it. But we are talking 1 gallon per 3 minutes. This wouldn’t be a problem if the tank wasn’t 86… Ideas?

A pinched, bent, clogged, or plugged vent hose would be my first guess if it is a recent development. Those dang dirt dauber/ mud wasp critters are great at plugging vents and water outlets.

More, your vent line may do a vertical loop before it gets to the external fitting (I think it is supposed to). If it does, you can get condensation build up over time (or fuel - but that would evaporate) that will cause a little puddle to gather in the bottom of the loop. Even if it does not do a full loop, a low spot will do the same thing. Once that happens, it won’t vent very well. So, check for dirt daubers, like Cracker Larry said. Then, if you can get to where the vent line enters the tank, disconnect it and try to blow it out clean.

Take. Note I had this same problem with a Pioneer it was not clogged or bent the inside of your fuel line might be deteriorated or eat up the gas was non e just a few times and made the inside of my gas line look like wet soggy card board. Have it inspected immediately caused me a whole heap of trouble with all the debris going back in the tank. The line could not be replaced or removed had to run a new fill line up from my tank inside my console. I am almost willing to bet that is what’s going on. The sooner you figure it out the better off you will be it was a nightmare for me and my boat was only 3 years old and pioneer would not warranty it. Good luck and let me know what you find! The description you gave was dead on .

unless gaining access to the sender caused an issue, changing the sender shouldn’t have been an issue
