2-stroke fuel tank rubber parts

[JHZR2]

I have an echo blower and a husquvarna trimmer. Both are leaking fuel out of the grommet where the fuel lines go into the tank. Very annoying.

I assume they can be easily replaced? Any recommendations for parts sources? Should I do anything else when doing this (like fuel lines)?

Both run perfect and efficiently, start first pull even after sitting for the winter.

Thanks!

Just had to re-do mine last fall.

The little hoses going from tank to carb get hard and brittle after a few years and need replaced along with ony other associated rubber parts (grommets etc.). Your local small engine shop should have a selection of them. Some long surgical stats really come in handy in pulling them into the tank. You'll want to replace the primer bulb along with the hoses too. If you can get non-ethanol premium fuel for your mix, it will prolong the life of the hoses as ethanol makes all the rubber parts get brittle quicker.

I'd go ahead and replace the fuel lines while you have them out. If the grommet is showing signs of aging, the fuel lines will be right behind it. Non-metal fuel system parts except for the gas tank are pretty much wear items on a 2 stroke engine, at least with ethanol in the gas.

Both companies make parts manuals available on their consumer websites. ereplacementparts.com and partstree.com stock parts for both brands.

If that grommet is bad, it's quite likely the flex tube, internal to the tank is bad too.

Blame it on Ethanol.

Is the flex tube replaceable?


Thanks all for the information. Will hit my local shop and see what they have.

Yes. It's actually the fuel line that's in the tank. There is a weighted fuel filter on the end of it. You'll want to replace that too. Pulling that line in is where a real thin needle nose pliers comes in handy or better the surgical stats.

I haven't had problems with fuel lines or other rubber fuel components on my Stihl equipment, which makes be believe that ethanol resistant materials are available. Most of mine is 5 to 10 years old.

Tygon fuel line can be ethanol resistant to varying degrees and newer equipment is designed to handle up to about 10% ethanol, but it can do a lot of damage in equipment not designed for it over a long period of time.

I purchased the entire fuel line assembly from e-bay. Comes with grommet, vent,filter, and all hoses. Replaced them on all my lawn equipment. Ebay was much cheaper than local shops.
