Re: Rochester carb, what's this hose barb for?
The clear hose is a visual telltale, if your fuel pump develops a leak...big marine safety thing.
The line, and the barb, need to be cleared!
^^^^What he said.....
..... AND more importantly....
It needs to be reconnected to the fuel pump....
Marine fuel pumps have a double diaphragm, when they start to fail they will leak gas from where the other end of that hose belongs,
leaking gas directly into the bilge creating a potential for explosion....
The purpose of the hose is to dump the gas into carb, instead of the bilge, & will make your engine run poorly, forcing you to investigate the cause.....
If you see fuel in that line, you need a new fuel pump....
VERY dangerous condition there & it needs to be
corrected/re connected IMMEDIATELY...
It is also a Coast Guard violation that you will be ticketed for if you are stopped for inspection.....
Be glad you asked this question.....
