Want to replace all my fuel lines, what size line do I need to purchase?

Do you want to replace your fuel lines w/ the OEM black rubber lines or something else?

Personally, all it took was one tank removal with all those OEM fuel lines which were cold, cracked, and hard as a rock!! I decided I wanted to get something better.

Goto to Home Depot and you can find 5/16" ID clear, vinyl fuel tubing from Home Depot. It is definitely easier to work with and it is cheap (~$5 for 20 feet). If it gets loose or whatever, just replace it. The only thing I hadn't planned on is the "clear" vinyl does seem to discolor more than I would have thought.

Just my $0.02

Do you have a problem w/ the line kinking on you, as with the reserve line to the back of the fuel selector the OEM line with the "U" bend in it?


I might have to try that because the OEM lines are nearly $6 a piece :guns:

I failed to mention that I removed all of the network of hoses and vacuums and replaced it with a single straight line from my newly installed Pingel tank petcock straight to the carbs w/a fuel filter in between. I also put a quick disconnect in between to make it fast and easy to remove the gas tank.

Quote from: Jace009Do you have a problem w/ the line kinking on you

I used clear poly fuel hose (similar to Scratch), except that I got mine from the bike shop.  They do squish quite a bit more than stock (especially since the stock hoses have that stiff shiny black plastic hose cover).  Mine are a little bit squished where they pass by the frame, but not kinked.  But in the short fuel line up to the carbs, I added a straight inline fuel filter.  Since the filter hangs down, the bottom end of the filter is pointing mostly down.  But from there, the hose runs straight back to the petcock.  So there is a little kink there in the hose, before the filter (it hasn't caused any problems, and I need way more fuel flow than most).  

If I were doing it again, I'd use a fuel filter with a right-angle inlet nozzle.

BTW, I had several problems with the stock hoses: trying to work them off the tank, I poked small holes in them with the screwdriver; I used screw-drive hose clamps, which chewed-up the old black hoses too.  The new hoses slip on and off easily (I can pull them off with just a tug), but still hold well with no leaks with hose clamps.  They don't get chewed-up by hose clamps.
