The fuel hose from the tank with the filter on the end goes to the fuel inlet on the carb ( conection nearest to the pump cover held with a single screw ) then take a pipe from the other carb conection to the short conection on the back of the primer ( suction side ) now take a pipe from the longer conection on the primer ( pressure side ) back to the tank, the primer pulls fuel from the carb and dumps it back to the tank

It does not start

During maintenance or replacement of the hoses it is easy to swap the hose connections at the primer. The center connection from the primer connects to the return hose that connects into the tank. The feed from the carburetor connects to the side connection of the primer bulb.

If the tank is full it can fool you as you prime because the return line to the tank that is full can be a pickup of unfiltered fuel and bring debris and air into the carburetor.

The primer pulls the fuel through the carburetor purging the air out. Usually seven strokes are recommended. You can observe through the primer bulb the air as it is purged resulting in no air left in the primer or carburetor..

I replaced my well pump and put everything back where it was. I prime it and plug in and pump runs but I got no pressure and no water comes through. I even put hide in line from the well Any ideas

it still needs priming all the way down to the foot valve
try putting a hose fitting in the primer hole and with a good water supply ( tank, garden hose ) turned on run the pump until you get a good supply the turn of the primer hose
if you have an air leak the pump will stop pumping after a few seconds as it sucks in the air and the prime is lost
could indicate that there is no water at the foot valve

Try swapping the hoses at the primer bulb. You may have put the return hose on the purge side of the primer bulb.

Air in fuel line?

get a container with fuel(about 4 liters will do). put a hose from the Primer to the fuel container and another hose from the injection pump return line to the container. if it works fine then the air leak is between the tank and the primer.

I have a broken primer bulb for an Echo CS-3400 chainsaw. I need to replace it but am not sure how to remove the old bulb. I can access it but am not sure if it will be necessary to remove all the guts of...

You should be able to get to it if you just take off the cover that surrounds it. If you do not yet have a bulb purchased, I would reccomend trying the site I have below. I have also put the part number you will need to enter in the 'Search' box on the site to get the right bulb.

Replacing a fuel line for a Poulan 2175 type 2 chainsaw

Take top cover off(3 screws). Take off the 2 nuts holding the carb on. Pull carb part way out to access the hoses. Remove the 3 old hoses after making a diagram of where they connect. Buy new hoses. Cut one end of the small hose on a bevel, pierce both sides 1/8 th inch from the end with a needle. Thread a thin wire through both holes. Thread both wire ends into the gas tank. Use a hemostat or long needle nose plyers to pull the wires and then hose down into the tank. Attach the weighted fuel filter. The other end of this smaller diameter fuel line goes on the upper nipple on the carb. Take the side cover off (4 screws) to access the primer bulb. Take 2 screws out to remove the bulb which has 2 nipples. The longer nipple connects to the larger diameter hose which goes to the fuel tank. The larger diameter tube has a coupler on the end which is inside the gas tank. It took me an hour to change all 3 hoses.
