Pressure building in fuel tank

Fuel tank is getting pressurized some how. I thought maybe the line for the primer was switched around so when you push the bulb it pressurized the tank but I switched the lines and it still does it. All you have to do is pull the starter cord and the tank is pressurized. If you pull the line that runs from the tank to the carb the gas just shoots out it. What could be causing this?

Where does the fuel line from tank with filter fit on walbro carb.also where does the primer line go?


The fuel line from the tank fits to the main fuel inlet on the carb ( the inlet nearest to the alloy pump cover secured by a single screw), the other conection on the carb has a pipe that conects to the shortest conection on the back of the primer ( suction side ) a pipe then goes from the longer conection on the primer ( pressure side ) back to the tank, it just pushes into the top of the tank.
So to recap the primer pulls fuel from the carb, and dumps it back into the tank.

I'm trying to get an old weedeater/poulan 22" excalibur hedge trimmer running for my son. In the past someone has cut a fuel line going to primer bulb. I replaced that line and when I use the primer...


There are 2 different set ups for fuel lines on these 2 stroke carburetors. One has a remote primer/purge bulb and the other has the primer/purge bulb on top of the carburetor. Here are instructions on how both kind work and how to service them.

The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so If you have any more questions, please post back. I will see your comment and be glad to help you,

Attempting to replace fuel lines on a Poulan 2550 Chain Saw. I need a detailed explanation of which lines go to which ports. Two different size fuel lines. It appears big one goes to the filter in the...


The size of the fuel line doesn't really matter if either one will fit on either port on the carburetor. When you pump the primer put a finger on one of the ports. If the primer goes flat but does not fill back up, you need to hook the fuel line with the fuel filter on it to this port. If you pump the primer and the unit will not go flat unless you remove your finger, you need to hook up the fuel line that just returns the fuel to the fuel tank. Make sure that no fuel will leak if the fuel tank is pressured up. To check just shake the saw a couple of times. This will build up pressure within the fuel tank, you should be able to tell if the tank will leak quickly. Best of luck.

Chrysler voyager 2.8 crd 2006 wont start without pumping the fuel primer replaced fuel filter and housing . checked in tank no primer pump found ?


Even though your vehicle starts and runs but dies, Your fuel pressure doesnt seem to be pushing enough pressure. It could be a faulty fuel pressure regulator.

When you prime/puge your carburetor, make sure fuel (w/ no air) is moving from the fuel tank towards the body of the carb. Also, make sure that there is fuel/air bubbles leaving the primer bulb and going back towards the fuel tank...and that when you push the bulb down and release it, there is no fuel movement in either line. If fuel does move when letting up on the bulb, you either have the fuel lines reversed or, the check valves in the primer base assembly are not functioning. The primer/puge valve's funcion is to draw fresh fuel into the fuel pump side of the carb and to push old fuel/air from the metering chamber side of the carb back to the fuel tank. Here is proper fuel routing:
This is an ongoing issue for users, and rightfully so. Small diameter line out of fuel tank (has filter in-tank on end) connects to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then pushes any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Years ago on 2-stroke trimmers, primers were not even used,...you choked the carb with a slide lever and gravity let fuel enter the carb from above...a few pulls, a "pop"...slide it off of choke and away you went.
If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank.

Should be two fuel lines coming from fuel tank grommet. One feeds the carb's primer plate and the other returns from the same. Open the fuel tank and observe while pressing the primer. If you see fuel pumped INTO the tank while pushing the primer and pulled FROM the tank when the primer is released, you're OK. If not, the lines are backward. Filtered line is on SUCTION side of primer bulb. Unfiltered line is on PRESSURE side of primer and is simply a return to the tank.
Next, concerning the coil: Air gap should be .010 inch at the magnet. Echo ignition coils are warrantied for life to the original purchaser, so don't tamper too much with it. Check gap and check fire with a spark tester. If no spark with switch in on position, take it to an AUTHORIZED SERVICING dealer, found here.

Hope this helps,

McCulloch Chainsaw carb not getting fuel


This is the same problem I have with a Mac 3200. I have: (1) A line from the primer bulb to the front port on the carburator. (2) line from fuel tank, with attached fuel filter, to the other primer bulb port. (3) Line from port on back of carb. to ????. I thought it must be a pulse line, but not certain, and don't know where to run it to. Please let me know when you find out.

Replaced fuel lines and pressing the primer pump does not feed gasoline to the car.


Sounds like you have the fuel lines switched around. The fuel line closest to the primer bulb will be the shortest line. It only goes 1" or so into the tank. The other line will be the longest line, and sometimes the smallest in diameter of the two depending on the size of your trimmer, and must rest comfortably on the bottom of the tank.
