One line out of the tank is the carb, It usually goes through a filter and /or a pump to get there, one line is the overflow drain, and the other is possibly a vent. If you have fuel in the tank, and only one drips, it goes to the carb, if the others drip, then I will need more info, make, model, year, all that. Hope this helps.

I took apart to 510 to clean I have little spring & ball bearing where does it go. It idles on full throttle

Hello Kerry McKinney,

I'm sure "510" means something to you...
(You really need help? Full nomenclature works best).
((I have no IDEA what carburetor YOU have here))...

I know (once upon a time) there was a DATSUN
by that name "510"... You posted a comment on other gardening tools so I suspect that is your area of concern.. To pull
Your fuel like out of your tank you can use forceps our fashion a wire or paper clip into a hook and GENTLY pull up the fuel line...

(even a hemostat might work)...

The "ball & spring" WERE a CHECK VALVE until
you misplaced them... blow into the end of the fuel line and fine where it come out of that carburetor body... that is where the ball goes in first, spring behind... which will keep the gas from flowing freely into the carb... but allow fuel when vacuumed from the engine...

CARB =====//////O>=============== TANK
'.... FUEL-LINE ......'

You SHOULD try to find a REBUILD KIT on-line
because everybody dreads seeing THAT SPRING flying
out of something the open... and the INSTRUCTIONS in the "KIT" will usually help with that...

a drop of red food dye gently put into the tank end of the fuel line... and GENTLY ADVANCED with a syringe should help you find that BALL-SEAT... Use come CARB-CLEANER to get it out before re-assembly. If you must use gasket seal... use only the recommended amount of a big NAME like Permatex..

Sloppy re-assembly with silicone sealant is the biggest
cause of AMATEUR small carburetor "CLEANING"
troubles (well that and looking... isn't cleaning).

CLEANING means using a solution made for the purpose to DISSOLVE dried dirt and petroleum products for the carburetor body (follow manufacturers instructions (not more petroleum)).

I recommend Berryman's Carb & choke cleaner (below)

Finally as to "idle" at "FULL THROTTLE"
(nah... Can't be connected )

Re-connect that throttle linkage... properly.

Have 2 gas lines dangling in gas tank, mcculloch 42c, 36cc, older, one line has filer other for primer????? or did it come disconnected

Hi perfecthelme...
Those are broken fuel lines your are seeing and a fuel filter inside of the tank
I will include a fuel routing drawing.
Before you remove any fuel lines, make a drawing or take a picture of how the lines are connected to the tank for later reference.
You will need to remove all the old fuel lines and fuel filter out of the gas tank.
Clean and remove all trash,broken pieces of fuel line,etc. from the fuel tank.
After you have all the fuel lines and filter removed.
You need a piece of wire...smaller diameter than the inside of the fuel line, insert the wire into the fuel line until it exits the fuel line then bend a hook on the end of the wire to hook over the fuel line.
You will lubricate about 1 inch of fuel line with a small amount of vasoline or light machine oil...
Now using your fingers or small needle nose pliers collapse the fuel line around the wire hook and insert it into the hole in the fuel tank.
After you have the fuel line in the tank, extend enough fuel line into the tank to exit the fill spout of the tank and remove the wire from the fuel line.
You will insert the new or cleaned fuel filter into the line and pull the fuel line to pull the filter just back into the tank.
Please take time to rate me

I'm trying to replace the primer bulb (no problem), the fuel and carberator lines. I can't figure out how to get the old lines out of the tank and how to get the new ones into the tank. I'm...

Hi ghutch...
I will also include a picture of the routing of the fuel lines.

Make a wire with a small hook in the end and reach into the fuel tank and grab the wire with the hook and pull the line and filter out of the tank.
Now is a good time to clean or replace the fuel filter.
After you have the fuel filter and fuel line removed from the fuel tank you will insert a wire into the fuel line and bend a small hook at the end over the new fuel line that your going to insert into the fuel tank,lubricate the outside of the fuel line (about an inch) with vasoline.
Now you will push the fuel line into the tank using your fingers to start the line in the hole and also pushing a the same time on the fuel line.
Once you have the fuel line in the tank move it to the fill hole and remove the wire from the inside of the fuel line and attach the filter and drop it back in the fuel tank.
Please take time to rate me thumbs up.

I have a craftsman chainsaw 2.2 cubic and there are 3 fuel lines two comming from the primer bulb and one going from carb into the motor or crank. The return is connected to a nipple on the crab and the...

This is a common problem. The fuel lines can become brittle and fracture, or sometimes they swell and will not stay on their connections.

The tube that connects between the carburetor and motor is likely used to pulse the fuel pump that is internal to the carburetor.

The primer pulls the fuel through the carburetor drawing the air out. As the primer is stroked first air than fuel is pumped out of the carburetor. The output of the primer returns to the fuel tank. That fuel line appears to have failed or become disconnected in your craftsman. Either the hose has broken at or near the fuel tank, or has pulled out of the tank. There is a small hole in the tank for many machines. The hole is smaller(providing a seal) than the tube diameter requiring a minor force to squeeze the tube back in place.

Look for the fuel feed tube that also connects from the fuel tank to the carberator. Any loose connections will allow air into the carberator and it will not beable to run.

Important is that the fuel feed tube can not be switched with the return tube from the primer. Connected inside the tank is a fuel filter that protects the carberator from contamination.

Hope this helps?

I just cleaned the carberator and new sparkplug it sounds like it not getting fuel when i put alittle gas in the carberator it starts and obviously stops? on my craftmen weedeater

if it is an older one, the gas lines like to rot away. you can usually tell by looking down inside the gas tank. you can also check to see if the primer is moving the fuel through the lines as you prime it

Homelite 10947d set for year cleaned good clean gas and oil pulled plug looks good cleaned got it running got some rpm but does'nt have power is there a gas filter I can clean

The filter is dangling inside the fuel tank on a length of fuel line toward the back of the tank--use a hooked wire to catch and pull the filter out of the tank. Check the line end for decay while there and replace the line if in trouble. The far end of the line is attached right at the carburetor body. Use original line type, not plastic. Check the muffler for plugging and repair or replace it if damaged. Hope this helps!

1987 jeep wrangle will not start or run

Uncouple the fuel line coming from the pump at the carburetor, place a clean can under the line, and have someone operate the starter--you should have fuel shoot from the line in spurts as the engine turns. If it does, then the entry port on the carburetor is plugged. Remove the float assembly and pull out the float needle valve. Hook the fuel line back to the carburetor and try the starter again, there should be fuel pumping into the float bowl. If not, check to see if there is a filter on the fuel inlet path that may be plugged. If no filter, remove the float needle seat to see if something is blocking the fuel passage. If all else fails, use compressed air to blow backwards through the needle seat (remove the fuel line again). Hope some of this helps!

Took tank off weed eater and not sure how the lines go back on

The line with the fuel filter in the end comes out of the tank and it goes to the bottom fitting on the carburator. The other line comes out of the tank and goes to the bottom fitting on the primer bulb, and the third section goes from the top fitting on primer bulb to top fitting on carburator. Got it? lol Hope this helped and best wishes.

Getting new gas lines in holes in gas tank

I had the same problem. I ended up cutting the fuel line off at a sharp angle. This allowed me to fit enough through to reach with a pair of skinny needle nose pliers. I would also like a diagram of the lines to make sure I hooked them up correctly.
