The small diameter fuel line that has the fuel filter in the tank on it goes directly to the carburetor (with the built-in primer or externally mounted primer). IF the carb has the external primer, the small line goes to the nipple on the carburetor opposite the end with the hole in the cover. If it has the built-in primer on it, it goes to the carb body on the nipple furthest from the bulb. The large diameter line is the fuel return line and if the carb has the bulb on it, this line connects on the nipple closest to primer bulb.. With the externally mounted primer, this line connects on the longest nipple coming out of the primer and goes to the fuel tank (not the filter though). There is a nylon connector inside the tank that holds this larger line in place. The shorter nipple on primer bulb has a smaller diameter fuel line connected to it and connects to the nipple on the carb closest to the end with the hole in the cover. Built in primer has 2 fuel lines...externally mounted has 3.

    You Are The Man. My 15yr old son pulled the lines out, trying to help Dad, and I was having difficulty getting my weed eater fuel lines correct and it running. Your explanation is simple and precise. You explain this issue with great expertise. It is great to have people like you out there. Thanks a Bunch.

Cut the end of the line at a sharp angle. Spray WD-40 on the line and fuel tank hole. Slowly screw the line in the tank far enough so you can connect the fuel filter if you are replacing that line. If not just push the line into the tank if you have a two line system. Remember on the fuel primer, the long tip has the line going to the tank, and the short tip has the fuel line going to the carb.

SOURCE: Ryobi 725R fuel filter; How is it re-mounted?

after you insert the fuel line through the tank and install the filter. take some WD-40 and spray the hose. now from the bottom of tank the pull on the hose. and just keep pulling on it till it comes through all the way. then slide the little white washer back over the hose and seat in place. this should do it for you. they are a royal pain in the **** to work on. numerous brands of string trimmers have these top mount tanks. a new tank with hoses already assembled is about 45 bucks with shipping. much cheaper to fix it yourself.

SOURCE: Craftsman 32cc Weedeater -- need fuel line diagram

The smaller diameter line (fuel supply) goes from the fuel tank (w/filter) to the carb body. Another larger line (purge line) goes from carb body to the right nipple on the primer bulb. Another large line (return line) goes from the left nipple of the primer bulb into the fuel tank. co0mpleting the purge circuit. This info pertains to my 2006 Craftsman 32cc with Zama carb.

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.

Cant find fuel filter

The fuel filter is under the car near the fuel tank (see diagram below). It's a canister with a fuel line threaded into both ends of it. You will need a 20 mm wrench to hold the filter and a 16mm line wrench to loosen the line fittings. You may also be having an ignition problem. All ignition components are under the aluminum top engine cover.

@aol.comMy Son has a 1996 FireBird 6 cyl, and had to replace the fuel filter in the gas tank. When he finally had enough time to finish it he had forgotten where all the fuel lines went. Is there somewhere...

The fuel line comes from the tank to the fuel filter, goes tru the fuel filter to the fuel line going to the engine injector fuel lines which deliver a mist of fuel to the engine cylinders to make the vehicle run.

Need to know how gas lines go on a RGB3100 they rotted off need to see a diagram

I don't have a diagram, but I can explain to you the fuel line routing.
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.
