SOURCE: 1985 Yamaha xj700 Maxim- Carb. fuel lines

yes, the breather line hooks to the petcock on the line facing the back, the fuel line hooks to the larger one. the line from the breather is actually a vacume line that turns on the fuel, without it you will not get fuel out of the petcock unless it is in the prime position.

SOURCE: I think someone hooked up fuel lines wrong. The

not that familiar w/Yamaha,but disconnected vacuum hoses may connect to fuel petcock at tank.I know Honda uses a system that only allows fuel to flow when vacuum is supplied.

SOURCE: Where could I find a fuel line diagram for a 92

For the fuel pump portion you can go here - http://www.bikebandit.com/houseofmotorcycles/1992-yamaha-motorcycle-xj600sd-carburetor/o/m8199sch138373

Two hoses come from the intake area under the carburetors - the small hose on the left side (facing front) which is directly under #1 intake goes to the Fuel Petcock vacuum input. The hose under #2 intake goes to the Fuel Pump - vacuum intake (marked with P). The left side of the fuel pump is the input for fuel - the right side is the output for the fuel pump - the hose goes up to the small T input between carburetor 2 and 3. The input for the fuel pump has an inline fuel filter and that runs up to the Fuel Petcock fuel outlet.

SOURCE: 1985 yamaha maxim 700 wont start no fuel. however

I had the same issue with mine, just recently purchased the bike, previous owner said it ran but has been in storage a year and a half. I filled the fuel filter and everything and it would **** down the fuel but never even attempted to fire. I came to find out that there are two lines that come off the tank, the one without the fuel filter has a vacuum on it. So what we did was pour a little fuel down that line to prime the engine because it dumps fuel straight between the carb and cylinder. Took about 3-4 attempts but it fired and ran, just had to set the idle from there. Hope that helps you.

Where does the fuel Draw line enter into the fuel tank?


I would make sure your line in tank isnt floating and I have heard about the rubber lines forming vaccuum and collapsing temporarily. I would blow out your lines and check fuel filter and I have some diagrams with parts list should show you everything you are wanting to know, good luck!

Its a 1985 Yamaha xj700 maxim that has a problem with the fuel and vacuum line, from the fuel tank to carburetors and drain line diagrams


Hi, Sevensons7 always check fuel flow first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve/petcock not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing*
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn*
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working*
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.
* If equipped or applicable.

if you take and clamp off the hoses and remove them from the tank,then support the fuel tank,remove the fuel tank holding straps then lower the tank,disconnect the wiring and make sure there is nothing else connected to the fuel tank,remove fuel tank transfer any components to the new tank and re-install.

Go under the van, the fuel filter will be in the fuel supply line, the fuel supply line is a 3/8" steel line. I will say that this symptom is not really a fuel filter symptom

I have a 88 F250 flat bed.The old fuel line that goes from gas cap to tank went bad so i replace it. the new line doesnt seem to be working out very well. When i try to put fuel in; it just seems to blow...


What size is the new line in comparison to the old one that went bad?? If the line is too narrow in diameter, it will not allow the air to rush out when you put fuel in it. The intention of that particular line is a 'breather' for the gas tank. Try a larger size line.

if the fuel is getting past/through the filter and to the distributor head ,make sure all lines are on fuel pump inside tank ( access under floor inside trunk ) also see if the is fuel to the injector lines, undo a line and see ,check for fuel at the cold start injector.poor fuel pressure can be a pressure regulator issue ( small gey box attached to fuel dist head attached by 2 screws )
