I noticed it's wet inside hose, are these simple to repair?

Simple to replace.
Repairs sometimes work, sometimes not.
You need a new diaphragm. -
Great, that's what I was hoping. are the z1 aftermarkets ok or better to use suzuki part?

cool Thanks!Comment

Are you sure your petcock is not working, did you test it?Comment

Fuel in the hose can only come from one place.Comment

petcock works good (though I haven't "tested it") but must have a small leak internally into vacuum portat petcock and just want to correct everything best I can. Looks like there's about 4 gaskets/seals to refresh but z1 only shows the 1 diaphragm, guess I better look further.
I also would like to know more about checking my float levels with bowls on cause I think I'm on the high side which I believe would set me up for a richer running condition which I want to stay away from somewhat.Comment

You might want to make sure it's not just condensation before spending the cash on a petcock. A clear tube in place of the vacuum tube should help.Ed
To measure is to know.

A bit pricey, but youll never replace it again..AND ..I have tried 2 rebuild kits and each has failed for whatever reason. What you do with this is simply put a tee in the vac line and run one to the tank and one to this inline fuel shut off.
EDIT....This will handle the fuel line...but just how to get around the leak into the vacuum line your gonna ask ?? I think I would simply put the pingle in the fuel line and remove the diaphram all together so the petcock will flow continuously, because now the pingle will shut off the fuel. Put a rubber cap over the vacuum nipple on the petcock. Put a paper gasket in place of the removed diaphgram.

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

wow that's strange that you've tried twice without success? Had you used genuine factory parts on either repair? It just seems so straight-forward. Interesting work arounds at an affordable price too, but I really would rather keep it all stock. Maybe I'll put this one on the back burner until spring arrives! lolComment

Some of the petcock bodies are too corroded, and some of the petcock kits just do not fit, at all. It depends on the petcock.Comment

Had the same problem. Terrible fouling on the #2. Derp. Boss said they never really had luck with rebuilding petcocks and we didn't have a diaphragm kickin around but there was a brand new petcock. Not cheap at all but here are the part numbers:
FUEL COCK O RING $5
44348-31051
COCK ASSY, FUEL $110
44300-45011
We might even have one in stock, I'll have a look.Comment
