I have a pretty new tohatsu 6HP outboard
with an impossibly small built-in tank and a fitting for an external tank.
The fitting doesn't appear to be what the marine
shops suggest is a "tohatsu" fitting. Mine looks more like the yamaha fitting, with a separate stud to snap it in place. (See attached photo
for what the tank-side fitting would look like).
I measured the piece on the engine
, the fuel
barrel is 3/8" diameter, the stud for snapping the fitting in place is 1/4" diameter, and they are about a half inch apart center-to-center. I went to the store and bought a fitting that appeared to have the same measurements, but it's a real bear to get it to snap on, and after about 5 uses the o-ring in the fuel
fitting failed. It makes me think I'm using the wrong fitting. Any insights??
