This might save some aggravation. I recently got my dads xl-850 going again. I am having a little trouble with dirt clogging the screen in the carb so I am planning on flushing and adding a filter in the tank. Anywho... I was going to use it this weekend, wouldn't run, right cleaned screen, still no luck. time to pull the carb and clean again, flush tank. WAIT A MINUTE- the fuel line in the tank rotted off....
hope this saves some grief for someone. Dan

yes. old fuel lines will turn to mush. I rebuilt a pre 1970 xl-12 that had the original lines in it. the line in the tank crumbled in my hand and the filter dropped out.

Ok, it already has a filter. How do I put new line in the tank? Does the tank fitting thread out? Thanls Dan

did you pull the old line through the hole in the tank. sometimes i get long needle nose pliers and reach in tank and pull line out.

The old line is out. How do you reconnect to the fitting in the tank thanks Dan

I redid my XL-903 fuel line and used two different sizes of fuel line. I pulled the smaller line that goes to the carburetor through a larger line that I used as a grommet. Homelite used a couple different arrangement in this family. Does your XL-850 have an elbow that is threaded into the tank? If so, just remove it had add a new line.

Thanks mine has 2 different size lines as well, looks like 3/16 outside the tank and 1/8" inside. It does have an elbow going into the tank but I was sure if it was pressed or somehow welded in. It seemed pretty tight and I didn't want to trash it. I'll get the torch out and heat it! Seriously I'll try the cold shock in a can to loosen it, I have used here and there but I can't say if it really was did the trick. This should tell me thanks Dan

The IPL picture shows that the elbow is threaded so it should screw out. Might have some sealant though on the threads.

ok, time for plan b, I turned the elbow off. Does anyone one have a replacement that threads into a XL-850? GRRR Any ideas what to do next? drill out then try and use an easy out bit? dril out entirely and retap. Are fittings available locally that would work? Thanks Dan

The later saws in this series used a metal tube with a 90 deg bend and the tank had a grommet. In an earlier post I mentioned I used two pieces of fuel line, one as a grommet, to install a line in my 903. The XL-923 used a one piece fuel line that went all the way from the filter to the carburetor. The SXL-925 went back to a metal line with a 90 deg bend and two pieces of fuel line.

mine has (had) a 90 deg. fitting going into the tank, 1/8" inside, 3/16" outside. I'll post what I do next, not sure yet.

The 90 deg tube on the 925 was not threaded, it fit into a grommet that was molded into the fuel line that was inside the tank.

So I finally made my own fitting, using a 1/8" pipe plug, 3/16" hose barb and a 1/8" hose barb. All brass. The 3/16" was easy, I just cut the threads off the barb. I chucked the 1/8" barb in my drill press and filed it down so it would fit into the end of the plug. Then drilled the cross hole in the plug, drilled and tapped the fuel tank and had a friend of mine silver solder the two fittings to the plug. Everything worked perfectly, and the ol' 850 is back to life. img849.imageshack.us/i/fitting.jpg/

In case anyone needs to go through this again, I have those fittings. Sorry, I know I'm late to the party.

Are the fittings that you have the threaded 90degree ones similar to the homebrew fitting the fellow above made? If so, I could sure use one. Could also use a few similar threaded fittings (with nipples for 1/8 ID line on the threaded end and 3/16 ID line on the other end) that are straight (not 90deg) for some non-red saws that take molded lines. Probably will end up making some if I can't find anything suitable...

I believe they are 90 degree threaded. The part number is 63297-A, I'll check it tonight when I get home.
