Hi best thing to do is to remove the tank first drain all the gas out into a safe gas can then remove the petcock and clean it making sure the tube and or internal filter are free of sedement the tube and passage ways are unblocked thats why no fuel is flowing in the on position.

Replace the petcock. The rubber diaphragm is ruptured. I'd also bet your fuel mileage dropped cause the ruptured diaphragm is allowing raw fuel to be sucked into the intake manifold.

Is gravity petcock for 03 suzuki Savage ls650 motorcycle better than the vacuum factory petcock? I'm changing to gravity had nothing but problems with factory setup


Hi, Paige vacuum fuel valves were a safety related upgrade from regular fuel valves they eliminate any fuel flow to the carburetor when the engine is not running no matter what position the lever is in for more information about your question and valuable "FREE" downloads that you will need please click on the websites below.

Drain fuel tank


Turn fuel petcock to off. Take off fuel line coming from petcock and use that hose, or one the same size, to run from petcock to gas container. (have paper towels or something ready because fuel left trapped in fuel line will leak out even with petcock off). With hose going in container turn petcock to normal "run" position and drain until dry - lean bike side to side to get it all. *Note - it usually drains faster with fuel cap off. Then turn petcock to "reserve" setting and do the same to get the fuel out of reserve partition in tank. Most tanks are only held on by a few bolts at rear and rubber "slide on" knobs at front, so if you remove seat and the few tank bolts you slide tank backwards and it comes off. Then you can do this draining outside / away from anything.

No fuel getting to carbs


If you have a vacuum operated fuel petcock, it should also have a "prime" position. That should let the fuel flow without vacuum from the engine. If this solves your fuel starvation problem, I would double-check to see whether the the replacement petcock gasket(s) may have shifted just enough to block some little pinhole that's required for vacuum equalization. That has happened to me--the replacement gaskets aren't exactly the same as what was originally in there.
You can also test the vacuum release of the fuel petcock without taking anything apart. Put a mity-vac (a hand-pumped vacuum pump) on the vac line to the fuel petcock and see whether you can get the fuel to flow. Harbor Freight sells a cheap mity-vac type pump for under $20 when it goes on sale (which it does regularly).
Good luck!

Reserve fuel does not work. Rand tank out of gas, switched over to reserve and could not start it. Had to refill gas tank and switch back to normal then it ran. Have to only run by mileage on main tank...


With the age of your machine , you should drain the tank and remove the petcock. If you can take it apart rebuild it. If you have no reserve , either the reserve tube is broken off or the petcock is plugged. It is possible the four hole washer the seals the the lever and diverts the fuel is damaged , worn , or broken. Depending on the over all condition of the petcock replacement of the entire unit may be the best option. At any rate an new fuel petcock would definitely fix this issue. Rebuilding your old petcock is only an option if all the parts you need for it are available.

Lt-f250x fuel vale has on- res-pri what is the pri position for


( PRI ) is the primer position for the petcock ( fuel valve) . This position is used for a couple of reason. this kind of valve works off vacuuum from the carbs, but if you run out of fuel you or remove the tank you can't create vacuum, so putting the valve into the PRI position allows fuel to flow inton the carbs without vacuum so you can start the bike. Once the bike has started you should switch the valve back to the ON position ON= normal position, PRI= primer position, RES= reserve postion. I hope this helps!!!

The motorcycle will run in the on position of the petcock....but will die as if it ran out of gas...gas tank full...I switch the petcock to reserve..n run great ....it started after I change an aftermarket...


problem is probably the fuel petcock try this test disconnect the fuel line and get a good length of clear line enough to reach a container hook it up to the petcock and turn the petcock in the on position and observe the flow of fuel to see if it is flowing freely try this in the on and the reserve position.
if it id restricted remove the petcock and clean the obstruction of rebuild or replace it.

The petcock on the 1980 GS1000G has no markings other than "Pr." To get gas flowing to the engine should the slot in the petcock be vertical or horizonal?


center poistion is on, PR stands for prime (gas always flows) and bypasses the vacuum controlled portion of the valve, the other poistion is Reserve. center is run and onlu delivers gas when the engine is cranking over or running, thias is the normal position u leave the tank selector in..

Bought a 1995 suzuki gsx600f and can't get started. does anyone know which way the petcock needs to face for reserve right,left, or down? thanks


I have a 1990 GSXR1100. If it's the same as mine, which it probably is, then as u r looking at it REServe should b to the left. RUN str8 down and PRIme on the right. The petcock has small writing on it to indicate this.
