The supply line coming from the stone filter goes to the short nipple on the prime bulb and the line out from the long nipple on the priming bulb goes to the fuel nipple on the carb that is the closest to the muffler. The return nipple is the closest to the choke and it goes back to the hole in the tank that is the higest. I hope that helps.

SOURCE: need diagram on fuel lines on a 26 cc craftsman weed eater

The longest, and sometimes smaller in diameter of the two fuel lines, goes from the carburetor to the bottom of the tank. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.

The other fuel line goes from the primer bulb to just inside the tank, (about an inch). make sure that you get the right size fuel lines. The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank.

(HINT): When feeding the lines through the tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.

If you need further assistance, just let me know.

Where do all the gas lines hook up on craftman model 358.791170 on primer it has a long nippel and a short nippel to hook to it is a 2009 32cc model


Take the primer bulb off and use two new fuel lines and dip them both in fuel. Push the primer bulb to see which side returns the fuel, this is the line that will go from the bulb to the tank, the other line goes to the carb.

What else should i try


Sounds like the check valve in the primer base is stuck/clogged/damaged, assuming the fuel lines and fuel filter are intact and not clogged, It will have to be replaced.

I have a Craftsman chainsaw model 358.352160 and had to replace all my fuel hoses and filter. Now I can't get fuel to the carburetor and the primer ball will not pull fuel from the fuel tank.


Sounds like you have the hoses hook up wrong.

The hose from the tank goes to the bottom of the Carb. The line from the top of the Carb goes to the inlet side of the primer bulb (put your finger on one of the ports and push the bulb, if it collapses without returning then thats the inlet side). The outlet side of the bulb should go tank.

Good luck!

The primer pulls fuel through the carbruetor
So take your return line from the carb. and hook it to the inlet side of the primer and the other side
of the primer bulb transtions into the fuel tank.
You know when you have hooked it up right when you press the primer it fills with fuel and dumps back into the tank.

I change fuel lines. when i push the primer bulb, there is no gas coming up. the primer bulb is in good condition


You need to make sure the fuel lines are hooked up properly. This is a common error when replacing fuel lines. Not knowing what model equipment you have I will take a stab at the routing. One line goes into the tank with a filter and the other end hooks to the carb. fitting closest to the fuel pump side of the carburetor. One line goes from the "out" of the primer and is a return line straight to the tank. One line goes from the "in" of the primer and hooks to the other fitting on the carburetor. If any of these lines are interchanged, you will not get the proper prime. Hope this helps.

Troybilt TB90BC fuel line schematic? I have replaced fuel lines that degraded with age and am uncerttain about the correct hook to tank, carburetor and primer. A diagram would help


easiest way to tell you is that the primer is there to pull the fuel through the carb. so fuel filter line goes from tank to carb, then from carb to primer and then back to tank as a return. if you forget which is the in line for the carb just hook with gas in a jar and try sucking it out of the jar. put filte rin a jar. and run line to carb , then line out of carb to primer and line back to jar as a return. if it pulls freely and fills the primer bulb your ready to go. if it pulls hard or not at all something is wrong.

Replaced gas tank and primer bulb on my Poulan Leafblower FL1500 and it appears I'm not getting gas into the carb. Any ideas as to what my be the cause?


I assume the new tank came with new fuel lines and filter in it.
First be sure you have all the lines hooked up correctly. There should be a main line from the tank ( has the fuel line on the end of it in the tank) to the fuel pump side of the carb. Then there should be a line leaving the metering side of the carb to the primer bulb then from the primer bulb returning to the tank. When you press the primer bulb you should see it **** the fuel into the carb then from the carb into the primer bulb then back into the tank.
If the fuel lines are all hooked up correctly then you should rebuild the carb.

Gasline mixup


one line comes directly from the fuel tank (the one with the filter) to the inlet side of the of the carbruetor ( the bottom fitting on the carb.usually)
the other line coming out of the fuel tank is the return fuel line and it hooks up to the outlet side of the two fittings on the primer bulb
the other side of the primer bulb goes to the only fitting left to hook to at the carbruetor.

you have 2 different length fittings on the primer bulb itself
the longer fitting is your return line hook it up to your tank side and the short one goes to carb.fitting
when you get it hooked up press the bulb several times and see if it primes as it should(fuel moving thru lines) from tank thru carb. thru primer back to tank
