The 2 spigots between the 1st & 2nd carbs are for the 2 vent hoses.the 4 skinny hoses on the bottom of each carb. are for carb. bowl overflow.

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

XJ900 1983 tank removed and there are 4 hoses to connect. Where?

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.

What is the best way replace the fuel lines. and what kind of lines can i use

I take it that you replaced the fuel filter as it is probably blocked now.. Fuel continually flows through the lines and it would take a big piece to block them unless it is the fine filter at the end of the pickup pipe in the tank

Fuel lines rotted. Replaced but cannot prime. Primer pushes back into tank causing fuel to leak at cap vent. Would like to obtain parts manual

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

I have recently purchased a line trimmer split shaft(hbc26sjsnb) and it will not start>Only way I can get it to fire is to dip spark plug in fuel ,but then it fires up but will not run - do I take...

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
Good luck

I have a 1983 Mitsubishi Starion. I recently purchased it from a neighbor who has let the car been sitting. The fuel hose that connects to the Throttle body has a pin size leak in it and squirts fuel out....

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.

Where does the duck valve go in a Poulan 2150 chainsaw? Iam trying to replace the fuel lines . Does it go in the fuel tank? I need a diagram of the fuel lines.

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.................
