    The rubber piece that you mentioned. Was this inside the tank?
    The supply tube has a filter cartridge attached inside the tank. You just dump it out, insert the new tube into the tank, fish the end out, and attach the filter. Insert the filter into the tank, and make sure that it will go clear to the bottom. This is necessary so the fuel can be drawn.
    The return tube end just needs to be inserted a short way in the tank.

Yes, you are right. The larger line goes to the primer bulb and only goes into the tank about an inch. The coupling just keeps the line from pulling out of the tank. The smaller line goes to the carb. This line must rest comfortably on the bottom of the tank with the filter attached to the end.

SOURCE: I need to replace to fuel lines on a Craftman 32cc

Depending on the brand of line you use, Tygon line is self sealing but seems to shrink faster then factory supplied because of the ethanol in the gas. The stone gas filter is designed to fall to the lowest part of the tank, not stop the line from falling out.

SOURCE: replace fuel lines,craftsman weedwacker,

Fuel filter in tank with line going directly to the fuel pump side of the carburetor This is the end of the carb with a solid cover. . This line should have length in it inside the tank where it can flop around and stay on the bottom to collect fuel. The other line in the tank should have one of the little connectors on it and can be right up to where the hole in the tank is to hold it there.. This line should connect to purge/primer bulb on the longer outlet nipple. Another fuel line should run from the metering chamber side of the carb (the end with the hole in the cover) to the purge/primer bulb with the shorter outlet nipple.
The purge bulb "pulls" fresh fuel out of the tank via a vacuum created after depressing the bulb and the fresh fuel flows completely thru the carb and any air or old fuel ahead of it are drawn to the purge bulb which then "pushes" this mixture back to the fuel tank.

SOURCE: need to know how fuel line end in fuel tank on a

Your Craftsman trimmer is made my Poulan/Weedeater and uses 2 different sized lines. The smaller diameter line is the fule supply line and runs from the pickup filter in the tank to the supply side of the carb. The supply side is usually the lower of the fuel nipples on the carb. Make sure to put enough line in the tank so the filter can drop to the lowest point of the tank while you are trimming. The larger diameter line is the return line, and will connect to the nipple on the carb that is closest to the primer bulb. From the factory, the return line went into the tank and had a small clear plasted connector on the end to prevent it from slipping back out of the tank. This fitting does not connect to anything in the tank, it is merely a return line. If the return line fitting is missing, just make sure to leave a couple of inches of line in the tank. If the filter is missing, you MUST replace it...it will save you from having to clean the carb out every 10 minutes of run time.
Good luck!

Gas leak at grommet on gas tank where gas lines enter and leave tank


Yes you should be able to replace the rubber tank seal that the fuel line goes through. Be sure to replace the fuel line(s) when you do.

How do you replace the fuel filter on a Weedeater PE 550 lawn edger?


You can find replacement fuel filters at a nearby hardware store. Once you have one, fish out the line from inside the tank and fit new filter onto line and place it all back into the tank. You will probably have to back out the tube a little after re-installation.

My 32cc craftsman trimmer won't start. i looked in the gas tank and there was a small tube floating around along with a black piece that was attached to the cap.


The leash to hold the cap is a common item to break and really doesn't need to be repair unless it bothers you or leaks. The tube that is loose is probably the cause of not starting. It is likely that the fuel line(s) have broken and are not allowing fuel to the carb. Your trimmer should have 2 line. The smaller diameter line will connect to the fuel pickup filter in the tank. The larger line is a return line and has a small plastic fitting on the inside of the tank that keeps it from slipping out. The replacement lines are available from you local mower repair guy or from www.searspartsdirect.com . If you choose not to tackle this yourself, the local shop will probably charge $25 to $45 for this repair.
Good luck!

The filter sounds like the weighted type. If so, it keeps the pickup line on the bottom. The piece that keeps the tube in the tank can just be a piece of a little larger tube pressed over the pickup tube. Yoi will have to thread new tubing in and pull it out the fill hole. Place the keeper on the tube and press the filter into the pickup tube. Once you are ready, pull the pickup tube inti the tank until the keeper touches the tank side. Hook up to the primer and try it. Good luck...Lee

Best Poulan Engine Match (probably real manufacturer):
http://www.ordertree.com/modelinfo/PWE/BC2400-Gas-Trimmer-Type-6/75.BC2400-Gas-Trimmer-Type-6.1.59.1.html

My decisions are being driven by my experience with Poulan chainsaws. Small hose in tank (long enough to reach all corners), filter on bottom, connects to lowest connection on carburetor. Small hose on upper carburetor connection to small fitting on primer. Large hose from large connection on primer through largest tank hole, roughly mid tank long. nothing on bottom. I suggest you leave the 2 connections on the carburetor long enough they can be swapped (just in case) then try it. if no go swap them.

This is how I would configure it if a chainsaw, doubtful they would do something completely different. In defense of Jerry, he knows how it should be done, clarity of instruction could use some help. Good Luck. HTH

My Rioby trimmer ned fuel hoses change how i do?


Typical fuel line routing is:

One line (the one with the fuel filter in the end of it) comes out of the fuel tank and goes to the bottom fitting on the carburator. The second line comes out of the tank and goes to the bottom fitting on the primer bulb. The third section of line goes from the top fitting on primer bulb to top fitting on the carburator. Hope this helped and best wishes.

Dry rotted tubing on my weedeater blower.


Have it replaced at a lawnmower repair shop.
1.) Have them check the grommet (black round rubber like a thick coin with 2 or 3 holes), replace it if it is crumbly. It holds the fuel line and the fuel vent line - if your trimmer has it. Grommets on the average cost about $6.00. Not all trimmers have fuel grommets, some of them only have holes right on the fuel tank. 2.) Replace the fuel line with Tygon fuel line hose. Tygon can withstand UV light, petroleum, high and low temperatures while retaining its shape. Just make sure the replacement tube is of the the same inside diameter. For a small piece of Tygon hose, ave. cost no greater than $8.00. 3.) Replace the fuel filter. The one inside the tank, connects to the end of the fuel line. Fuel filter, good ones are about $4.00.

Need to know how fuel system and fuel lines are installed fuel lines dryrotted cant determine where to hook each line can i see a diagram


Line from tank with the filter on it is the supply line and goes to the carb inlet fitting. This is typically on the "bottom" of the carb (with the tank being up) and will usually have a fitting with barbs or a bulge on it to ensure a tight fit. The other fitting on the carb is the return line and is usually a straight tube fitting with no barbs. That line goes the suction side of the primer bulb. The third line goes from the outlet of the primer bulb to the return barb fitting in the bottom of the tank. Fittings have to be removed from tank to properly install the new hoses on them. Remove retainer ring on outside of tank and push fittings into tank, then shake out of the fill opening. More details on proper installation follows.

If yours is like all the Ryobi units that I have seen you just need a piece about 12" long of 1/8 ID fuel line. You can usually order that from parts suppliers or get it at some lawn and garden repairs shops. Hardware stores will not likely have it. There is a fitting with a hose barb on it that fits through the tank. On the outside of the tank on the bottom there will be a round plastic ring, assuming the fitting is still in place and just the hose split at the fitting. Use a knife or thin blade of some type to pry off ring. It is actually around the hose that is over the barb. Keep ring, you will need again. Now push fitting up into the tank. You may have to trim off the hose that is outside the tank on the barb to get it to go into the tank. Shake tank around and get fitting out of tank. You will see there is a piece of hose on it yet. Remove that piece of hose. Now take the new hose and slide it onto the barb. It must go all the way to the top of the barb fitting so that the hose actually goes into the tank through the hole drilled in the tank. The OD of the hose acts as the seal to keep gas from leaking out of the tank. You may need to put some oil of some type (vegetable oil works well) on the barb and inside of hose to help slip it on and use some pliers with smooth or rounded jaws ( no serrations, will damage hose) to get hose on. Thread other end of hose into the fill hole of the tank and out the hole in the bottom of the tank. Hint: Straighten out paper clip or use small wire inserted into the hole from the bottom of the tank up towards the fill opening. Slip tube over that and use the wire to guid the tube directly to the opening. Pull hose through the tank. When fitting with barb and hose over it reached the hole in the tank it will resist being pulled through. Carefully pull firmly on hose to stretch it so the hose/fitting "bulge" pulls into the hole in the tank. Look into tank and see when top flange of fitting is tight against the bottom inside of tank. You should see bottom of barb outside of the tank with the hose on it. Once in place put the plastic retainer ring back over hose and push up to bottom of tank. It should fit snuggly when you get to the "bulge" area. Cut hose length as needed to fit onto straight tube fitting on primer bulb. Should be good to go. You may find that the other hoses are getting bad also and may want to change them at the same time, as they will probably be ready to crack also. You can reuse filter from tank if it is not plugged, just add a new hose as described previously. Otherwise you can order a new filter with the line already on it. That line goes directly to the carb inlet barb. That barb is also hard to push hose on. Third line is from the return side of the carb to the suction side of the primer bulb. That is just a straight piece of 1/8" ID hose and pushes onto straight tube fittings, very easy to get hose on compared to barb fittings.
