2015 bass buggy 18dlx fuel tank

[Steveo2122]

I recently purchased this pontoon boat and when i took it out for the first time i notice that the engine would kind of Bog down when i gave it full throttle. it would hesistate a little and then gradually pick up speed. went back in and then changed out all the fuel filters to see if maybe one of those was gummed up and they were. but still had the issue. finally unscrewed the gas cap and it went away. alot of pressure hisses out when i unscrew the cap so i figured it needs a vent. bought the stuff i figured woudl be used for the vent line and am super confused as to which line i splice into for the vent line. any help identifying each line would be awesome.

Welcome
The one small line should be connected to the motor with primer bulb

The link below should be close to how yours is put together
Vent System

thats what i would assume it looks like but the actual line to from the tank to the motor comes from the oppisite end of the tank. its weird lol and the large lines and small line run to that other end also. i was debating cuttin the larger line at the top of the fill neck and splicing in the vent hose there

One of the hoses should go to a vent fitting mounted on the outside. Probably small and have a drip loop. Find that line a trace, could even remove the hose end and blow out. Around hear we can get mud dobbers fill the opening with mud

i will look again. i havent been able to find the vent fitting anywhere on the boat. i know (from research) that they have something that the dealership was doing for the later models 2018 plus. i ordered a borescope so i can hopefully see better towards the middle of the boat and hopefully see if and where the vent is.
