  • Fuel Fill very slow

    Curious what I can do to help a fuel fill problem. I have a 260 and unless I put fuel in slowly, it gurgles, bubbles, and fuel spits up and out, shutting off the nozzle. The vent is working. I fill until she starts to spit fuel out the vent. Gas station pumps have 3 stops I can lock the handle to the ON position. I can't even use the first of three.

    Thanks,

    Partial obstruction in your vent line most likely.

      In addition to a blockage in the vent, you could have an obstruction in the fill line. Things like the cap seal from a bottle of additive are common. You could have a degraded fuel hose also where the inner lining has degraded or collapsed.

          Try turning the handle of the pump 45 degrees, to the left...and then to the right...sometimes you can get a cleaner flow of fuel by doing this...

            How old is your fill line? Mine was almost impossible to get gas in. Pulled my tank and looked in the fill line and the inner liner is almost completely collapsed and my vent was full of evaporated ethanol dust. Line was from 2004

                Changing the pump handle angle does help, but not quite enough. The fill and vent lines were replaced by the previous owner less than 5 years ago. I have the coffin lid off, and lines visually look good. Next is to remove the rod holder panel and see what's behind it. I'll remove both and make sure they are clear.

                    Can try one of these. No idea if they work but always wanted to get one for my buddy's Hewes that had similar issues.

                    Does your fuel line have a dip in it? This will cut off air flowing in the fill line, and while it will still work with a working vent, it means you're more likely to get periodic burps back at you.

                      Interesting. My fishing buddy just experienced the same problem on his 2 year new boat. It was intermittent. Sometimes it filled easily and sometimes it was slooooow.

                      He brought it back to the dealer last October and they couldnt find the problem. A few weeks ago he noticed wasps flying around and crawling into the overflow vent fitting. The mud dobber wasps were crawling into the vent fitting and starting a nest. Hence, the vent hole was blocked by the mud.

                      This may or may not be your problem. But its something for everyone reading this to be aware of.
