Question about Leaf Blowers

1 Answer

Fuel Leak I have a RGBV 3100 Mulching Blower Bacuum. It leaks profusely from one of the two fuel tube connections to the fuel tank. The leak occurs at the connection of the tube from the thumb press used for starting the device. The fuel tube to the motor from the fuel tank has a plastic gland. The leaking tube has no such gland. How do I seal this leaking tube going into the fuel tank?

    I have a model BL30, the gas cap has leaked repeatedly. Has there been a recall on this or replacement parts available. Either the cap or the tank are the issue.

Recommend replacing the fuel lines. They only last a couple of years before they get brittle. The fuel line if very inexpensive and can be found just about anywhere.

Fuel leak from carb when sitting

the return tube is blocked
the tank sends fuel to the carb
spare fuel is returned
also the cap usually has a bleader on it
perhaps its blocked up and needs the internal diaphram and filter block renued
if the carb leeks this also needs attention

Will not prime-new bulb-new primer base have rebuilt carb

Maybe a problem with the 'connector' (item 4) as its the only way for fuel to pass in and out the fuel tank. Obviously assuming none of the pipes are leaking. Also check the fuel tank vent (item 2), these have valves in and can often perrish and leak to atmosphire. 3_2_2013_11_33_39_pm.jpg

I have a Craftsman Leaf Blower (made by McCullough) and the fuel tank is leaking - need a new tank. Model #316-794990, Part #MC 9228-334506. Thank you!

Before you spring for a new tank, check that the leak is not coming from around the fuel lines. If the fuel lines are not soft and plyable then they can not seal with the tank and may be the cause of the leak. They are replaceable and if that is the case you can get fixed up for a few dollars in parts.

On my homelite leaf blower, gas is leaking out at the cap when i hold the blower pointing down...there appears to be a breather hole in the middle of the cap where the leak is occuring...should that hole...

No, the hole shold be open. There is a check valve in the cap which, when working properly, allows the tank to vent (lets air in so fuel will flow to the carburetor) but prevents fuel from pouring out. I'd first give the cap a good cleaning to see if that stops the leak. If not, you'll need a replacement.

More info, let me know.

Sears blower Mod. 358.797550, 2 cycle. problem with leaking gas after use on control / carberator side of blower

This is probably caused by a cracked fuel line, or loose fit of fuel line where it enters the tank. Try loosening the fuel cap after use just a bit, to let pressure escape, then tighten the cap. As the fuel cools, it will create a bit of a vacuum in the tank. Should cut down on the leak a fair amount, if not totally.

I have the Echo PB 265L leaf blower. When it runs it leaks fuel down my back. Seems to be coming out of a tub that is connected to the fuel button pump (which you push to prime when starting) I checked on...

I had the exact same problem with gas soaking my back and found out the yellow fuel discharge tube that comes out of the carberator was not inserted into the rubber gasket on top the fuel tank. The gasket has 3 holes in it for 3 tubes and the yellow tube fits into one of the holes. Hope this helps. It is a bit difficult to get the tube in the hole, but at least if you know what you are looking for you can get it to work

Fuel leak after I shut off the blower and set it down.

Well, if gas is running through your engine and out the muffler, there's a lot of fuel inside the crankcase and I doubt that you would be able to start it. My thought is that there is a cracked fuel line or fuel tank, with emphasis on the fuel line. You may want to take some housing parts off to see if you can see a drop of fuel hanging on the fuel line where it may be dripping and running over to the muffler area.

Husqvarna 145BT gas blower with a gas leak. this is at random some times it leaks from the bottom right down my lower back. Some times it doesn't leak at all. Not to sure where leak is coming from.

I own the 145BT.

Mine will leak when one of the two tubes (one black and one yellow in the picture) that come out of the gas tank pull out. I find this is usually when someone hits them when priming the carburetor, just before starting it. I just push either the black or yellow tube back into the black rubber gasket on top of the fuel tank. The gasket is pretty tight so it sometimes takes a bit of effort.

More than once I had quite a bit of gas on my clothes by not making sure they were pushed in completely, before putting it on my back to start blowing.

The tubes should probably be a bit longer -or may have shrank a bit over time.
