Question about 1988 Yamaha XV 535 Virago DX

1 Answer

I think someone hooked up fuel lines wrong. The bike runs out of fuel when the fuel switch is on. Both lines out of tank go to secondary tank and bottom line on secondary tank has fuel filter and goes to inlet of fuel pump. Trying to find a better diagram than the one i have. Please help. Also on the top of carbs there are two hoses that look like they might be part of vacuum system that are not hooked up to anything they are on back side on diaphram part of carb. Please help. This is a 1984 yamaha virago xv 1000 that has been made into rat bike. I didnt do work just bought it and trying to fix it.

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.

My bike bike runs on main tank even on low fuel..it somtimes shows some missing. I think my reserve tank doesn't work.Any suggestions?


Check the reserve fuel line and the main fuel line to make sure they haven't been switched. I purchased a Suzuki Intruder and was riding all the way to reserve to check the mileage and when I ran out I couldn't start it even though I switched to reserve. Turns out that someone had the tank off to service the air cleaner and had reversed the two fuel lines so the fuel valve was running the bike on the reserve tank tube. so when I switched to the reserve position it was hooked to the taller brass tube in the tank and the gas level was already below it. The tanks just have two brass tubes, one taller than another so gas cannot be sucked below the taller tube when on main and then when switched to reserve it sucks from the shorter tube allowing the remaining gas to be used.

Working on a friends 81 yamaha 650xs. I removed and cleaned the carbs and put them back on but can t remember how the T hose from the petcock to the carbs hook up. Can someone help me


The petcock on these bikes is vacuum operated, which means that there are two hoses that go to it. The thicker hose is the fuel line and it runs from the thick port on the petcock to the fuel input on the carburetor rack. The fuel input on the carburetors is located between the number two and number three carburetor bodies. If you aren't sure which is the fuel connection, just turn the petcock switch to prime for a second and you will see gas come out of the fuel connection.

The thinner hose on the petcock is a vacuum line. It runs from the vacuum port on the #3 cylinder (between the carburetor body and the engine) up to the smaller connection on your petcock. When the engine is turning vacuum is applied to this thinner line and allows fuel to run from the tank into the carburetors.

There are the only two lines that should run to your petcock, and the fuel line should not be split anywhere between the petcock and the carburetors.

Good Luck,

I am trying to help a friend out and get his 08 nightster 1200 running for him. this bike has been sitting for almost a year. took tank off and cleaned it out and installed new battery for this unit. ...


Make sure the fuel line from the tank to the injector is seated fully. The fittings must be secure for fuel to flow from the pump. Make sure the pump is plugged in to the harness, and the fuse is good. There is a way to check the fuel pressure, but you will need the proper fitting to hook to the tank along with a pressure guage. It is possible that the fuel line from the pump inside the tank is cracked or not hooked to the pump or tank outlet. Hope this helps.

My dirt bike fires up and only runs for like 20 seconds what is wrong with it


There could be a few things to look for when this happens. I found on my KLR 650 i had a bit of rust or dirt in the tank that had clogged my fuel line by the shut off. If the bike has been sitting, the fuel may have gone bad or started to "gel" in the bottom of your carb bowl causing the float to hang up or flood the bike out. Hope this helps.

Replaced the fuel pump fuel filter , no start in my 95 S10 Blazer. add gas will run, untill the gas stops pouring in by hand . new part on top of the throtle body as well, i think it controls th O2 and...


1. Does the pump actually run (key on engine off) pump should run for 2 seconds and go off and can be heard if you listen at the filler neck with the gas cap removed)
pump not running - Check relay (replace if bad) check wiring/fusese

Pump runs... go on to #2...

2. check the gas guage. is the gauge reading in the normal area it would read in or is it way way off like WAY above full or way below empty? This is a sign the electrical connection at the pump is plugged in backwards and the pump is spinning the wrong way and not picking up the fuel... (This is easy to get plugged in backwards inside the tank when installing the new pump)

3. Check for feed, return and vent lines being installed wrong where they attach to the tank... they can easily be hooked up wrong and fuel is either pumped up in to the return line or pumped in to the fuel tank vent line..

4. check for kinked or crushed fuel lines from tank to engine.

5. check fuel pressure regulator to be sure its not stuck open.

Fuel pump on 64 Impala is pumping but no gas from tank.


Ground wire in the tank won't do you any good,You can hook a low pressure air line to the fuel line under the hood and blow the clog back into the tank and then run an inline filter as close to the tank as possible.That way the filter will catch the clog and you can just replace the filter when that happens.
