What fuel tanks for the Stihl 066/660.

[Bill G]

I have either a later 066 or 660 that got dropped and broke the rear handle. I am not sure if the tanks are the same on the late 066 and the 660. Does anyone know?

An easy way to tell Bill is if the saw has the black plastic filter base. Those bases were used on the later 066 with rounded covers and 660 and those saws use the same tanks.

If it's an earlier saw with the orange metal filter base - those tanks are different. The tanks won't interchange without changing a lot of other parts.

I will take a look when I get home tonight. I know it is a "round top" so I am thinking late 066 or 660.

Is the tank also wider at the fuel tank to go along with the wide recoil?

Yessir. The black plastic filter bases won't interchange with the orange metal ones because the tanks and airboxes are wider.

If they had made the filter base for the newer tanks out of an alloy, it would have been a winner, same with the 661.

So now are any of the aftermarket tanks any good?

I have a Farmertec on my milling saw maybe 4 years now no complaints. Not used everyday though.

I'd get a new OEM if it was me.

I am not sure how much I want to sink into it

If you get an aftermarket tank, you'll need to upgrade the tank vent and fuel cap. Also make sure the airbox is mounted on the tank correctly and snugly. I would salvage the OEM trigger, trigger/interlock parts, throttle rod, wiring, and on/off switch from your old tank.

 

[Bill G]

I wonder how much an OEM one is. Now that we have no Stihl dealer anywhere in the area I cannot just stop in and find out. Stihl has ran away all the dealers here now that they have crawled in bed with John Deere and the chain box store Farm and Fleet.

Looking around online I'm guessing a new OEM is gonna be about $160 and a new farmertec is going to be about $40 bucks shipped from somewhere in the US.

My vote is to buy OEM. I went through 3 of the FarmerTec fuel tanks on my MS 460 before I finally bought an OEM one. All 3 leaked at the seam - 2 of them nearly right away, and one of them took a month to show up. OEM has been holding fuel leak-free now for 2 years, as expected. 660’s may be different..

I have one that I took off, put OEM on because the seam looked like it would separate sooner or later. Last place I want it separating is in a back cut.

 

[Bill G]

I do not have a Stihl dealer to get one from. They are just box stores and Deere

This is what Stihl did to dedicated dealers.

 

[PA Dan]

What happened at those dealers?

 

[Bill G]

Stihl crawling in bed with John Deere and box stores

Stihl crawling in bed with John Deere and box stores

That has affected a couple of the original dealers here too, but not on the service side of things. People figured out quick that the John Deere dealers just want to make a quick sale and don’t have the years of experience when it comes to servicing the equipment.

Stihl did not figure that out.
They forced dealers to devote more lineal feet of display space to their product and force the dealers to buy the displays. Most dealers who did great service worked out of small areas and had no physical space to devote more of.
