Can the vacuum petcock be bypassed to operate.

[Contndr]

Is it possible to bypass the vacuum operated petcock on my 2002 Venice to make it operational? I thought about doing this and installing an aftermarket inline petcock. Has anybody else tried this? I just bought a Venice and I don't know where to hook up the vacuum line to the engine.

the vac line should hook to the carb. If there is no place for it then you can "tap" it into the intake elbow.

I would save "drilling" the petcock as a last resort. If you do HAVE to, then just remove it, drill it and re-install it. Once you have it removed and in front of your drill, it should be obvious where to drill......

Thank you! I looked all over the carburetor and crankcase and I don't see any fittings to hook the vacuum line to. I wasn't sure if the vacuum made the valve work like a fuel pump or not? I didn't see any fittings on the intake elbow either. Thanks again for the information!

YOu can make it work without vacuum. But then it wouldn't be a valve. You can either install a manual type valve, or just let the fuel sit on the needle.
Some people take the valve apart, and remove the diaphram. I would leave the valve in place, just route the hose around it. Leave the vacuum line attached, and let it "operate" without the flow of fuel.

Any reason you don't want the vacuum valve operating??

be advised the carb may over flow when its parked if you bypass the valve.
someone not too long ago had the same problem couldn't
find the hose locations.. search in the fourm.. i told him in detail what hose was what and where they go.. look for my posts

It will overflow...especially when its hot outside, and the sun is beating on it. Hence the reason for the valve. The valve offers no performance advantage when disconnected, and flow's alot of fuel for 95 % of modders too.
