QuestionI have a 32cc sears blower/vac and all of the fuel lines have crumbled. I have 2 ports on the carb the primer bulb and 2 lines holes in the fuel tank. I have replacement lines but cant quite figure out the proper routing with exception that the small line goes from the carb to the tank with the filter on the end. The rest is a mystery.
Answer To be more exact, I would need to know the sears model number off of the small serial number tag, but in general, the routing of
the lines is the same.
These are actually not primers, but "purge" the air out of the fuel system, by pulling fresh fuel through the carb, and chasing the air out.
The carb has 2 nipples, one is closest to the cover on the carb
held on with one big screw, that is the fuel inlet nipple, and it is
attached to the line that goes to the bottom of the tank and attaches to the filter.
Now thye other side, the primer bulb only goes one way, so you need to find out which side "sucks" the fuel, which is easy enough.
So, the other nipple on the carb has a line that goes to the nipple
that sucks the fuel, and the other line, on the other nipple, then to
the other hole in the tank, just far enough into the tank to not easily pull out, so the fuel returns to the tank.
