The body is correct for my 78 GS1000, but the filter appears to be from a later G model of some sorts. It holds back fuel okay, but as far as seeing at what amount of fuel left in the tank before it will need to be switched onto reserve compared to the original one? I can't. The fuel tank is necked...

Eventually I'll fix it up to stock paint and decals, get a '79 tailpiece painted to match, then wither sell them here or use them for a "non-skunk" change of pace on the '78.GS450E GS650E GS700ES GS1000E GS1000G GS1100G GS1100E

You guys are awesome. Judging from the picks I at least have the correct one on my bike (E not G) . Unfortunately I have not been able to mess with it. My wife went into labor on Tuesday (6/19) and on 6/20 gave birth to Chloe our beautiful baby girl. First child I might add. I will take the info and hopefully at least have tome to take it off and clean it since I'm taking several days off. The PO said he rebuilt it if that's true the parts should be in good shape still and i can clean it out. I'll get back to you later. Thanks again for all the info.

Congratulations! Now you really have your hands full.
In the meantime, I'd just soak your petcock in gasoline and clean it thorougly, blow it out and see if it leaks before you tear it down, dirt, especially that little breather hole getting clogged creates allot of the problems.sigpic

My '79 petcock has that single tier filter, the '78 had the two tier filter,
The single tier filter works well, I was initially concerned that I wouldn't be able to use up all the fuel in the tank should I get low, but since it's never been a problem I just don't care.sigpic

Ok, so I took it off and soaked it in gas for 18 hours or so taking it out and trying to blow it out 4 or 5 times. No change. The vacuum works fine on on and reserve but it still won't stop dripping when its not running. I could buy a rebuild kit and try that. Z1 offers 2 replacements with the same bolt hole distance (44mm, measured it while it was off) but the site says neither of them will fit my bike. I don't understand why. A vacuum petcock is a vacuum petcock right. I mean it controls gas, this isn't rocket science. What makes a '78 model so unique that no other model will work. Can I not just switch it over to a gravity feed and be done? I played with it off the bike for several minutes and from what I gather its just open or close (with my original thought being it actually controlled how much fuel as to supply 4 carbs) oh yeah and i did figure out it is the check valve not working correctly. If i blow real hard on the hose it will shut off but when i release pressure it runs again. Is there a way to fix the valve and make itwork properly? The kit comes with O rings and diaphragm. What do I do now?

Pit, on some bikes, the airbox gets in the way of the fuel and/or vacuum port.
It also depends on the location of the valve on the tank.
Look carefully as to which type that you can use on yours.

I have k&n pods. That's also an issue. The gas coming from the overflowing carbs takes the oil off my filters and they don't work right.

Been looking around for upgrade options and i believe my best bet is going to be a pingel with an adapter plate. At just over $100 its twice what I was hoping to spend but its still way cheaper than the stock model for 260. But I wanted to ask about it on here before placing the order. Make sure Boone has had any bad experience with pingel, or if there's something I should look out for.

44 mm centerline spacing is what I got (see link below); both outlets face towards rear (as in pic). hangs down 1.7 inches from tank bottom on back vac portion. Maybe it would work , but I don't know. The reserve pickup "spot" is likely different
