Looking really good there Buc (-:
About the vent tube. Was there a tube in the old tank? If so did you copy the arrangement? I’m can’t remember how I did mine. But thinking about it now I have an idea as to how it should / could be .
The way you have it now, if you tip the motor forward gas will leak from the tube. Now if you were to extend the tube to the back far corner of the tank, no matter which way the tank was tipped it wouldn’t leak.
Yep’ , I just checked mine, as near that I can feel in side the tank , I did run the tube back to the corner. Now if you need 1/8 ” copper tube… auto parts store ask for an oil pressure gage kit.Joe
Joe, I’ll have to admit, I did not think about gas coming out the vent tube,
other than when it was running, hence I made it stick up about 3/4″
above the tank, figuring those old single bangers do a whole lot of shaking!
The original vent tube on the inside of the tank was bent toward the back
of the tank, maybe 5/8″, pretty much like what I did.
After the fact, I’m thinking the vent tube sticking up 1/8″ above the top of
the tank was per factory. My 3/4″ tall tube “may” work, but it has to be
up inside of the flywheel to clear, and it’s “close”.
The motor does not “tilt up” very far like a modern outboard while mounted
on the stern, so the inside of the vent positioned like mine would not
mater much. However, if one lays the motor on the floor on the back of
the gas tank brackets, it might help to have the vent on the inside go
to the upper front corner of the tank.
For my use, guess I won’t worry about it…… it would almost
be sacrilegious to lay the motor on the floor after all that work anyway!
Prepare to be boarded!
