Ryobi 990r Primer bulb and fuel lines

[AveryMarkR]

I don't see this model listed on your site, but that's what it says on the case. The fuel lines on this 4-cycle trimmer/brushcutter have exceeded their useful life. I tried replacing with generic lines, but they don't fit correctly and leak. The primer bulb has lost enough flexibility that it is probably not going to survive long. Have you parts available to replace these?

I've added the Ryobi 990r to our site, and the Fuel Line and Primer are available. You can find the breakdown page here:

Ryobi 990r Parts List and Diagram

The primer assembly is part number 791-181538, and you can find it here:
791-181538 Primer and Line Assembly - $13.40

The fuel return line is part number 791-181086 - $3.03. You can also get it in an assembly with a filter - 791-181085 Fuel Line Assembly W/Filter - $8.60

I'd still recommend taking a look at the breakdown page to make sure you're getting exactly what you need, but it sounds like those should get you covered.

Hope this helps!

Wa-Hoo!

I love forums. This was the part I needed!

I hate reviving old threads, but this is exactly the item I am servicing.

I replaced my fuel lines with standard lines a couple of years ago, and (like the original poster said) they leak like mad!

My bulb just broke as well, so I thought this expensive tool was going to have to be junked.

Is there a general "service kit" for this item?

No worries on bringing this old thread back from the dead. The more information we can pack into these things, the better.

The parts I mentioned above should cover everything you need:

Fuel Line Assembly W/Filter [791-181085] - $9.46 at eReplacementParts.com
Primer and Line Assembly [791-181538] - $13.40 at eReplacementParts.com
Fuel Return Line [791-181086] - $3.36 at eReplacementParts.com

The primer bulb assembly includes two fuel lines, but the return line included with it may not be long enough to reach back to your fuel tank. I'd suggest picking up the separate fuel return line just in case.

There's also an OEM Carburetor Repair Kit listed for that tool, which will include things like the internal gaskets, reed valve, diaphragm, needle, filter screen, etc. It won't include the specific items you're asking about, but it's as close as it gets to a general service kit.

By the way, that's a great picture of your trimmer. How would you feel about us featuring it on our 990r breakdown page?

Gotta love these sites and please keep up the good work! Just ordered my lines for my tank after finding they do not sell the tanks any more.

i recently changed the fuel line from the tank to the engine. after doing so the motor ran fine for half an hour then stopped suddenly, noticed a gas leak from the bulb which i need to replace but also oil leaking from under the cover over the bulb/carburator. Any ideas what the connection is and what I may need to replace to fix it?
