G day all,i have recently purchased a 1983 XJ900 in pieces, i am trying to get it back together but cant work out the fuel lines, i know where the main line goes in and the vacuum to the manifold but there are 2 more outlet/inlets between the outside 2 carbies, i dont know if they are breethers(i have got the 4 breethers coming out the bottom) or inlets or what if any one can help that would be great thanks Damien.
Thanks gpmoto, by saying they are vent hoses should i just put a bit fuel line out under the motor the same as the overflow pipes.Thanks for your help Damien.

the vent hoses usually arent quite as long as the overflow hoses, its not critical just route them away from hot exhaust. the vent hoses usually arent quite as long as the overflow hoses, its not critical just route them away from hot exhaust.

I could not find a parts diagram for a 93 XJ900 but I found one for a 750. All I could see was 2 hoses going to the fuel petcock. Not sure if the petcock is vacuum controlled, but the second hose might go to one of intake manifolds. This feature stops fuel from flowing when the engine is off. On California bikes it may also have a hose going to some charcoal canister(s) for capturing fuel vapor. On some tank designs their is also a hose that allows excess fuel at the filler cap to spill to the ground instead of spilling all over your tank.
i recently worked on a chainsaw that i was putting back together and got the primer bulb lines crossed, it was backwards to the way it should have been, i recommend that you reverse the lines, it is an easy mistake to make when it can be counter intuitive like it was in my case
This is a common problem for home owner machines rated for 50-75 hours of use. Is this Homelite "brand new" never used or is it brand new -only run a few hours? most machines will develop a problem after 30-60 days when sitting with fuel in them. This is because the 10% Ethanol in most cities leeches polymer strands out of the fuel system and combines them with the moisture of the air and oil in the fuel. This makes for a sticky white substance that blocks passage ways and sticks one way valves open.
My fix is to purchase a $20 jewelry cleaner at a local tool shop and clean the carburetor (located behind the air filter) make sure your fuel lines have not been affected or damaged by the Ethanol and put the machine back together.
Using a high quality oil such as Stihl Ultra Oil can help prevent problems. You can also purchase fuel premix with no Ethanol through shops like www.arcolawn.com.
Good luck
check air mass flow sensor, with this unit going bad it will make the car runs horrible. also make sure you getting proper fuel pressure with good working fuel regulator. If it has a tubo, check if the turbo charger still working and hook up especially down at the wast gate control vacuum line still hook up to the wast gate control.
is your fuel cap missing the hold down that keeps it from falling out of the tank.if the keeper is missing from fuel cap, the valve goes in the cap.if the cap is together then it just sticks in the fuel tank hole in the top...... hope this helps,let me know.................
