I have the same problem with my RedMax 7500.
It will fix itself. Mine is stored in an unheated shed in the winter. In it's first use, It seems like the fuel line shrinks a little due to the cold. Dry off the area and use it as you normally do.
The fuel line will expand and the leak will stop. It will no longer leak for the entire season.

Thanks Itzbinnice for the reply. Well I will give it a try and see what happens. Mine is leaking where the grommet seal itself to the tank. We have gotten another cold snap so it will be a few day before I get back outside to use it. ( I hope) I don't know about you but it seemed like an awful long winter.

Thanks Again

Yes it was a long winter for me also.
Mine war primarily leaking around the fuel feeder hose that went through the grommet. This year it didn't leak as bad as previous years and stopped leaking in about 5 minutes after use. The rubber shrinks so when things warm up it expands and a good seal is made.

Why don't you try bringing the blower inside overnight and see if that does the trick.

I will see what I can do about that. My wife gets upset when I bring anything associated with gas into the house. Thanks for the help and suggestions.
